Titanium rods with high strength and density and small, mechanical function is good, patience and resist function very well. In addition, the difference in titanium technology function, machining difficult, in the thermal processing is very simple to absorb nitrogen hydrogen carbon and other impurities. There are poor abrasion resistance, production process messy. Titanium industrial production beginning in 1948. Aviation industry needs to carry out, the titanium industry with about 8% of the average annual growth rate of conduct. Current international titanium alloy material production reached 40,000 tons, nearly 30 kinds of titanium trademark. It is the most widely used titanium alloy Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and commercially pure titanium (TA1, TA2 and TA3). Titanium is mainly used for the production of aircraft engine compressor components, followed by rockets, missiles and high-speed aircraft layout elements. The mid-1960s, Titanium sheet metal and its alloys have been in the industry generally use electrodes for the production of electrolytic industry, power plant condensers, oil essence and desalination heater and environmental pollution control equipment. Titanium and its alloys have become an anticorrosive layout information. Also used in the production of hydrogen storage materials and shape memory alloys. Titanium is the aerospace industry in the use of an important new layout data, the proportion between the aluminum and steel strength and use temperature range, but high strength and excellent corrosion resistance to sea water features and ultra-low temperature capabilities. The amount of Powder coating titanium in the aviation engine is usually 20% to 30% by weight of the total distribution, mainly for the production of compressor parts, such as cast titanium fan, compressor disk and blades, cast titanium compressor casing, intermediate casing, the bearing housing and the like. The primary use of titanium spacecraft high specific strength, corrosion resistance and low temperature capabilities to produce a variety of pressure vessels, fuel tanks, fasteners, instrument straps, architecture and rocket casing. Sputnik, the lunar module, manned spacecraft and space shuttle are also using titanium plates welded.
