    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.
Third, the laser - arc hybrid welding
Compared with conventional arc welding and laser welding, laser - arc hybrid welding weld penetration with a large , high process stability , high welding efficiency , strong weld gap bridging ability and welding deformation , etc., can greatly improve the welding efficiency and weld quality. Laser - arc hybrid welding can reduce the workpiece machining accuracy requirements groove welds may be titanium bicycle part improved over time high laser welding shortage and liquid bath due to higher absorption of the laser beam , laser welding can be compared greater penetration and a higher welding speed . Using laser - arc hybrid welding , laser and arc due to the presence of two heat sources , and each heat are more parameters to be adjusted , so make the laser and arc harmonic match with a lot of tests need to be explored .
Jiangnan Shipbuilding technology test results conducted show that plasma arc welding , laser welding and laser - arc hybrid welding excellent joint performance of the welded test plate . Process repeatability, low level requirements for welders , it is very suitable for the production of large quantities of rules seam welding.

Research electrolytic refining titanium tube technology issues

After studying the literature , we did not use a non- aqueous medium and low temperature electrolysis of aqueous medium titanium tube method . titanium bicycle frames Studied only the alkali metal and alkaline earth metal chlorides and fluorides consisting of salt melt and dissolved titanium compound. We know that a titanium 600 elements 900 ℃, gas (oxygen , nitrogen ) having a high reactivity , these impurities affect the mechanical properties of titanium , taking into account the impurities in the electrochemical process of Basking melt transfer medium titanium tube into the possibility of precipitation on the cathode , so we set ourselves a task - to establish the cell , in this cell to be able to ensure reliable external impurities in inert atmosphere and eliminate the possibility of contaminated electrolyte .

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.

Some common titanium products

            Some common titanium products
   Titanium washing tower is installed on the incinerator for processing very low levels of radioactive waste . 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).

‍From the Swiss road network information

‍From the Swiss road network information currently available to view, in 2013 the total output of the industry is in a state of slight growth , the growth rate of more than between 5 % to 8 % growth in individual sectors stagnated . The annual average price is lower than in 2012 , which resulted titanium bicycle frames in the majority of enterprise revenue is lower than last year. Meanwhile, the downstream product prices first drop, after drop upstream raw material prices , thus causing downstream enterprises to bear more pressure . Tension downstream enterprise funds , making widespread payment defaults occur within the industry . The spread of this case bottom , making 2013 the individual enterprise funds are plagued by varying degrees .
At the end of 2012 when the annual plan to do , the industry was optimistic the market will improve in 2013 . This also leads to a certain extent, when enterprises are facing a downturn , the difficulties are not sufficient to prepare . Preliminary statistics from the current point of view , in 2013 the national production of titanium sponge is still modest growth , the supply is higher than demand for titanium processing industry. When the increase in business inventories , the usual coping should be controlled in order to maintain profit margins yield . But in fact, some companies fail to make adjustments in a timely manner , yields rise, Titanium Artificial Joint not fall , resulting in a large number of products unmarketable. The product unsalable lead enterprise funds tight , which prompted enterprises to turn to loans from financial institutions . Although you can ease the financial pressure in the short term , but also to bring greater financial costs , potentially increasing the burden on enterprises. In order to repay the loan , some companies phased cheap Paohuo return funds, further exacerbating the decline in product prices , which thus caught in a vicious cycle .
After December 2013 the State Reserve policy began , some titanium sponge enterprises raise product prices , but signs of recovery as the market did not like before . Since downstream firms reflect flat, high offer titanium sponge enterprises become castles in the air , and soon dropped back to previous levels. And during the bidding , some companies did not follow the big companies with price increases, which is also reflected in the side after a long titanium sponge industry expansion has weakened the influence of leading enterprises . Manufacturers unsalable inventory into titanium sponge titanium ingots after , although the pressure of titanium sponge enterprises get some relief , but we also worry about the future market demand may Titanium Golf Club Heads be overdrawn in advance , thus making the market more difficult in 2014.
