The Uses And Properties Of Titanium Rods

Titanium rods have high strength and low density, good mechanical properties, and good resistance and corrosion resistance. In addition, titanium alloys have poor process performance and are difficult to process. During thermal processing, it is very easy to absorb impurities such as hydrogen, oxygen, nitrogen, and carbon. There are also poor wear resistance and complex production process. The industrial production of titanium began in 1948. The demand for the development of the aviation industry has caused the titanium industry to develop at an average annual growth rate of about 8%. At present, the annual output of international titanium alloy processing materials has reached more than 40,000 tons, and there are nearly 30 titanium alloy trademarks. The most widely used titanium alloys are Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and industrial pure titanium (TA1, TA2 and TA3). Titanium alloys are mainly used to make aircraft engine compressor parts, followed by structural parts for rockets, missiles and high-speed aircraft. In the mid-1960s, titanium and its alloys have been used in general industry to make electrodes in the electrolysis industry, condensers in power stations, heaters for petroleum refining and seawater desalination, and environmental pollution control equipment. Titanium and its alloys have become a corrosion-resistant structural material. In addition, it is also used to produce hydrogen storage materials and shape memory alloys. Titanium alloy is a new important structural material used in the aerospace industry. Its specific gravity, strength and operating temperature are between those of aluminum and steel, but it has high specific strength and excellent resistance to seawater corrosion and ultra-low temperature performance. The amount of titanium alloy used in aeroengines usually accounts for 20% to 30% of the total weight of the structure. It is mainly used to make compressor parts, such as cast titanium electric fans, compressor discs and blades, cast titanium compressor casings, intermediate casings, Bearing housing, etc. Spacecraft mainly use the high specific strength, corrosion resistance and low temperature resistance of titanium alloys to make various pressure vessels, fuel tanks, fasteners, instrument straps, structures and rocket casings. Artificial earth satellites, lunar modules, manned spacecraft and space shuttles also use titanium alloy plate welding parts.
