titanium sponge powder Strategic metals - titanium

Strategic metals - Ti (Titanium): element symbol Ti, atomic number 22 , atomic weight 47.88 , located on the 4th cycle Ⅳ B family in the periodic table . Titanium is one of the most widely titanium sponge distributed crustal abundance of elements in high (6320 × 10-6) , accounting for 0.61% by weight of the crust ranked 9 out ; resources are second only to iron and titanium , aluminum, magnesium and columns home section 4 is an important raw material preparation slag , synthetic rutile , titanium dioxide , titanium sponge , titanium and titanium , welding rod coatings. Because titanium silvery white , with a high melting point (1727 ℃), light weight ( 4.5 ) , high mechanical strength ( 5 ) , low temperature ( ultra low temperature resistance is almost 0 ) , abrasion resistance , good ductility titanium wire ( energy use thin wall ) , easy to oxidation, reduction , and other characteristics ; titanium oxide - titania ( titanium dioxide ) , with non-toxic , good physical and chemical stability ( after 1000 ℃ calcination does not melt at any acid and alkali ) , high refractive index ( 2.55 to 2.70 ) , and strong whiteness, color strength ( 1150 to 1650 ) , the hiding power (40 ~ 50g/m2), temperature resistance, and other characteristics of the powder , called "pigment the king . "

Thus , titanium and its oxides, it is important to paint alloy products , new structural materials , anti-corrosion materials , known as " after iron and aluminum in the development of the third metal " and " strategic metal" , but also " very promising metallic material " in the field of aviation, aerospace, ships, military industry, metallurgy , chemical industry, machinery, electricity , water desalination , transportation , light industry , environmental protection , medical equipment , has a wide range of applications , and create a huge economic and social benefits, has an important position and role in national economic development .

In a recent meeting of experts of titanium and titanium alloy Thirteenth National Symposium confirmed: From the perspective of cities across the country , in addition to outside Luoyang , China does not have a region or city has a complete industrial chain of titanium , however Luoyang City can titanium sponge production of titanium ingots , but also can produce titanium ingots into titanium mill until the production of titanium equipment. China is currently the only city which has a complete aerospace casting  industrial chain of titanium - " Titanium City ."

It is understood that , after 40 years of development, China has become after the United States , Japan, Russia and the fourth has a complete industrial system titanium country . Experts, a complete industrial chain of titanium , the main components products are: titanium sponge ( base material ) - titanium cast ( casting ) , semi-finished products , titanium processing material ( sheet, strip, tube , rod ) - titanium parts and titanium equipment manufacture. Although the country as a whole , China's titanium industry with complete system , but on a city or a region, currently has only met the requirement of Luoyang whole industry chain.

Titanium as materials research and application of marine focal point, located in Luoyang, China Shipbuilding Industry Corporation Institute is one of the seven two five research institutes to carry out a few handful of domestic titanium systems research , applied research in titanium areas represent the national level. In titanium industries, seven hundred twenty-five currently has an annual production capacity of 2000 tons of titanium alloy ingots , the production of titanium alloy golf head casting products represented , have occupied 1/3 in the international market share, making it important domestic titanium casting base . At the same time , seven hundred twenty-five titanium has been welded to the condenser structure represented containers manufacturing capabilities, particularly in the formation of the titanium complex represented shroud structure manufacturing capacity to titanium Equipment stroke among the domestic manufacturing base ranks.

Relevant data show that Titanium is a metallic element , gray, can burn in nitrogen , high melting point . Titanium and titanium -based alloy is a new structural materials , mainly for the aerospace industry and the maritime industry. Titanium is mainly used for the production of aircraft engine compressor components , but also for structural parts manufacturing rockets, missiles and high-speed aircraft. The mid- 1960s , titanium and its alloys have applications in general industry , mainly for the production of electrolytic electrode industry, power plant condensers , oil refining and desalination heater and environmental pollution control devices. In addition , seven hundred twenty-five built 10,000 tons of titanium sponge project , using the world's most advanced magnesium reduction - distillation - Electrolysis joint production process to achieve a closed process , auxiliary materials recycling , environmental compliance now produce qualified titanium sponge . As an important part of the titanium industry titanium alloy chain , currently , seven hundred twenty-five 5000 tons of titanium alloy sheet and strip and sheet and strip products have been approved by the National Development and Reform Commission annual project is actively under construction. Complete industrial chain in Luoyang City, titanium formed with a strong stability and competitiveness of industry , technology and scale have reached the international advanced level , to promote the significance of Henan great efforts to develop the next titanium industry .
Experts predict that in the next three to five years , Luoyang existing titanium industry will be based on the formation of titanium semi-finished titanium products and titanium casting equipment three industrial clusters. By then, these industrial clusters will bring annual sales income of 5.0 billion Luoyang this titanium industrial base.
