Difference titanium, aluminum

different , but sometimes they are just like some of the products , it is not difficult to identify them carefully observed , particularly titanium magnesium alloy doors and aluminum doors , details about the specific distinction below :
    1, the titanium added to the titanium- based aerospace investment castings alloy other alloying elements called titanium . Titanium has a low density , high strength , corrosion resistance , good process performance , etc., is an ideal aerospace engineering structural materials. Titanium and titanium alloy structure can be divided into heat titanium, titanium alloy , or α , β , and α + β type titanium alloy titanium alloy . Study also include forming technology of titanium alloys , powder metallurgy technology, rapid solidification technology , titanium military and civilian fields.
    2 , aluminum is aluminum made by adding some alloying elements such as aluminum - manganese alloys, aluminum - copper alloys, aluminum - copper - magnesium-based hard alloy, Al - Zn - Mg - Cu based hard alloys. Aluminum has a better than aluminum physical and mechanical properties : easy processing , high durability , wide application , good decorative effect , rich color . Rust-proof titanium bicycle frames aluminum into aluminum, hard aluminum , hard aluminum and other types of various types have their own range , and have their own code , in order for users to choose.
    3 , remains a lightweight aluminum features, but significantly improved mechanical properties . Application of aluminum alloy has the following three aspects : First, as the force components ; Second, as doors, windows , pipes, covers, shells and other materials ; Third, as a decorative and insulating material . After the use of aluminum anodized characteristics can be colored , made of various decorations. Aluminum alloy sheet, the surface profile can be corrosion, ginning , painting, printing and other secondary processing to produce a variety of decorative plates, profiles, as a decorative material.

‍Marine titanium welding process

In recent years, many new ships began extensive use of titanium alloy . With the increase in the amount of titanium alloy materials , shipyard welding to Titanium Welded Tubes enhance efficiency , product quality and stability , the need to develop some efficient titanium welding process. TA5 two kinds of titanium Shanghai Jiangnan Shipbuilding in thickness of 4mm Ti70 and 16 mm for welding object, plasma arc welding , laser welding and laser - arc hybrid welding titanium welding three high energy density of the process carried out explore, get the excellent performance of welded joints
A plasma arc welding
Plasma arc welding is the use of plasma arc welding method as a heat source . Gas heated by the arc generated from the solution , a nozzle at high speed compressed by water , and increasing the energy density of the solution from forming a plasma arc. Its stability , heat and temperature are higher than the arc , and thus has a greater penetration power and welding speed . For marine titanium welding tests show that plasma arc with concentrated energy , penetration , side welding good shape , no tungsten inclusions , less porosity , etc. , it is very suitable for welding of titanium and titanium alloys . More plasma arc welding process parameters , when the method is mainly related to the use of orifice nozzle diameter , titanium bicycle frames welding current, plasma gas flow rate , welding speed , shielding gas flow.
Second, laser welding
Laser welding is a focused laser beam as the heat energy generated by the bombardment of the weldment for welding a high -precision welding method . Laser welding due to the high energy density, obtained greater penetration and high welding speed , and because the diameter of the laser beam is extremely small, so narrow weld and heat -affected zone , the welding residual stress and deformation is small . The main parameters of laser welding laser welding power , welding speed , defocusing amount , side-blown gas flow and shielding gas flow. Since the laser welding high welding speed , the welding process generally can not adjust the parameters of the process , so before the formal optimum welding parameters to be determined by a combination of pre- experiments.

True and false of titanium sponge rods how to judge

Now, the application of titanium alloy rods is more and more widely, with the continuous development of society, some people in order to covet interests, produce fake of titanium alloy rods, shoddy, sales to the customer, make a lot of damage to customer interests, therefore we need to know how to judge the true and false of titanium alloy rods, avoid buying home of titanium alloy rods. Below, will introduce you to judge true and false of titanium alloy rods.

Judge true and false of Titanium Graphite Mold Casting rods the simplest method is the weigh in hand, if feel lighter, so may be pure titanium rod, this is the difference between titanium and the titanium frame is one of the most simple way.Because when the proportion of Sunrui titanium golf clubs frame is about 8.9 g/cm3, and the proportion of pure titanium frame is 4.5 g/cm3, titanium rod weight equal to half of the alloy frame. Weld mark as "steps"; Spot welding, the welding of titanium alloy rods investigate the nasal stem and the weld of box, and pure titanium material welding for anaerobic touch welding. Weld mark as "slope", this is the difference between titanium and titanium frame, titanium and non-uniform titanium frame of one of the useful way.

So, to see if there are any more gaskets, hinge place is the difference between pure titanium rods of a more effective method.

Some common titanium products

The device has been put into use in 1973 , titanium pumps the operating temperature of 160 a 250 ℃. According to the results of the last inspection , the titanium device is not found evidence of corrosion .
    Recently, the scrubber waste heat boiler in a pulp mill on the uniforms of water have been used titanium plates . 3l6L originally designed using stainless steel, 1979 replaced with titanium plates dehydrating it . These dehydrated plate for 120 ℃, pH value of the water cycle water cycle 3-4 aggregate a large number of hydrogen sulfide and sulfur dioxide gas . Using the results are quite satisfactory , and therefore , the plant plans to other scrubber systems all use titanium plate dehydration .
    Titanium is also being used in addition to the ttitanium valve need from the scrubber wash hydrogen chloride , and have achieved good results . The column was washed at a temperature of 140 ℃, pH value of 10-11 , a sodium hydroxide solution after two cycles of operation , the frame and mesh of titanium are not corroded . Therefore , the plant engineering have made handsome would rather invest in titanium does not require maintenance , rather than using plastic or fiber- reinforced plastic titanium pump Branch (FRP).

Titanium tube heat transfer efficiency to beat rivals

  From the viewpoint of heat transfer efficiency, we find that the titanium alloy pipes with other tubing (e.g., copper-nickel alloy) match. High strength titanium and high Titanium Casting Manufacturer impact resistance allowable turbidity of seawater with high flow rates and titanium alloys have a high temperature corrosion resistance, titanium-nickel alloy than copper heat exchanger 60 a weight reduction of 70%, the their overall heat transfer efficiency is roughly the same.
     Due to the longer life of the titanium tube structure to offset one-time investment, in terms of economic efficiency is also something else. And because of the speed for the entire period in the life of the tube can reduce downtime, thus also receive an additional character. With the growth and expansion of the use of titanium production, the cost and availability of titanium improved. aerospace investment castings Titanium also with 317L stainless steel, Monel alloy 400 and Hastelloy C-276 to compete. It is predicted that in the middle with seawater cooled heat exchangers, finned whole rolled titanium tube will completely replace copper-based alloy tube.

December 2013 Titanium Market Review

This month perovskite thin market , aerospace investment casting traders expect downstream manufacturers can then take advantage of the phenomenon appears Dongchu stocking raise ore price , but on the downstream market before the Spring Festival perovskite save more bearish attitude , procurement were significantly hesitate Dongchu stocking phenomenon later later in the future. And near the end , the buyer Yakuan serious , some businesses are willing to boost sales of low-cost shipping return cash flow. Imported ore more or less supported by the outer disk costs , limited the decline , while the Panzhihua region ore price confusion, repeated exposure to small factory prices low.
New Year's Eve , some Chinese companies have discontinued slag and advance into the Chinese New Year holiday state. Given the current trading price of the product is too low, the majority of companies have presented a loss. Affected companies choose slag based on customer orders to schedule production, lower overall industry operating rates. Meanwhile, the 2013 annual market performance is more sluggish domestic acid soluble chloride slag and slag showed a state of oversupply . titanium bicycle frames According to the Swiss road network is understood that there are some domestic enterprises chloride slag small amount of inventory , and the acid-soluble slag inventory is relatively high. In addition, due to the widespread downstream buyers to delay the payment date , the current domestic enterprises slag poor liquidity and high financial costs.
State Reserve policy affected by early December , some titanium sponge titanium sponge enterprises to improve the sales price , the highest price of 0 # titanium sponge over 52,000 yuan / ton. However, due to the downstream repercussions dull , no corporate procurement , the price has become a castle in the air , then quickly dropped to 4.9 yuan to 50,000 yuan / ton price . Titanium Casting Golf Heads According to a company official said titanium sponge , although the state had acquired a certain size , but because of the large amount of inventory on the market earlier , coupled with the downstream demand is not ideal , so despite favorable policies , but did not change the current market downturn titanium sponge trend. As of the end of December 2013 , the domestic price of titanium sponge is only 1000 yuan / ton symbolically raised , and the actual volume is still maintained at a low level. In addition, the purchasing and storage operations led some companies to obtain the melting orders for titanium ingot processing enterprises inject some vitality. However, due to the downstream market remains in the doldrums , making the purchasing and storage policies benefiting a narrow face .
Subsidence trough titanium sponge titanium industry wide losses
Throughout 2013 , we can say the whole titanium industry has experienced a very difficult year , the most obvious manifestation is the price of all products falling almost all year . Among them, the import price of titanium dropped from the beginning of 2300 yuan / ton to the end of 1600 yuan / ton , down 30% ; 90 slag fell from the beginning of 8000 yuan / ton to 5,800 yuan to 6,000 yuan / ton , down more than 25% ; 0 # titanium sponge price from 66,000 yuan in early / ton decreased to 4.9 yuan to 50,000 yuan / ton, down about 25 %. Currently, the price of titanium sponge was significantly lower than its cost , the titanium bicycle part companies are operating at a loss situation, few companies have been forced to stop production .
Affected by the downturn in the overall economic environment in 2013, non-ferrous metals industry generally face greater difficulties. Under this background , the titanium industry is not immune . Downstream products unsalable forcing down prices upstream manufacturers of raw materials, while the upstream companies had gradually compromise, bottom- price surges gradually spread to the entire industry . In addition, various manufacturers feel uncomfortable phenomenon is the decline in prices can not be picked up in exchange for sales , customer purchases always in tepid state.

Titanium castings in the aerospace engine usage and comparison of forgings

Titanium castings in the aerospace engine usage and comparison of forgings , can be seen, titanium precision casting with clear growth trend will gradually reach the amount of titanium forgings for each equivalent level. In particular, the application of cast titanium in civilian areas , for example, if the casting can be mass produced with great golf club head , which promote the use and development of cast titanium alloys . In China, Aerospace titanium casting for example , the country 's GDP growth in recent years, casting titanium rose more than tenfold. I cast titanium alloy and is in a stage of rapid development .

titanium sponge powder is mainly used in which a few respects

In the production process of titanium to toxic chemical medium chlorine (chemical weapons in World War II oh) and noble metal magnesium, and the reaction process requires a lot of energy, which is why titanium expensive. The smelting process oftitanium is not to be used for production, because it is porous shape, resembling asponge, called titanium sponge, titanium alloy pump will be placed in vacuum consumable electrode arc furnace smelting titanium ingots, plates, rods, tubes and for other formsof titanium production. Titanium is rich in resources, mineral resources are relatively concentrated, converted into TiO2 total reserves of 90 million tons, is the first in the world. The main distribution of titanium ore, the reserves accounted for 35% of the world's total reserves. However, compared with the world's major mineral producing area, natural Jin Hongshi (TiO2) less resources, easy exploitation of placer less.Titanium, titanium iron ore more symbiotic, smelting high initial cost. Here also need to refer to a story, the original iron and steel smelting steel slag after stacked in a cornerfor a long time to climb, we did not find this kind of slag inside unexpectedly containprecious metal titanium. Later proposed to buy our slag, concrete truth that make our national attention on the Panzhihua Iron and steel slag, of course rejected japan.

titanium sponge industry started in twentieth Century 1954 50 years, non-ferrous metalbegan to research on the preparation of sponge titanium, titanium metal as thestrategy on the 12 year development plan, in 1958 in the industrial test of spongetitanium, founded the first titanium sponge production workshop, at the same time,non-ferrous metal processing plant was established the first titanium processing material trial production workshop. Before and after 1980, the titanium spongeproduction reached 2800 tons, but because most of them were lack of knowledge on the titanium, titanium pumps high prices also limit the application of titanium, titanium processing material production is only 200 tons, titanium industry in trouble.
