Titanium alloy has high strength and low density, good mechanical properties, good toughness and corrosion resistance. However, the processing performance of titanium plates and strips is poor and cutting is difficult. During thermal processing, it is very easy to absorb impurities such as hydrogen, oxygen, carbon and nitrogen.
In addition, titanium plates and strips have poor wear resistance and the production process is complex. Among all titanium alloy processed materials, iron plates and strips account for nearly 50% and are widely used in various fields. At present, the world's annual output of titanium plates and strips has reached more than 40,000 tons, and there are nearly 30 grades of titanium plates and strips. The most widely used titanium plates and strips are Ti-6Al-4V (TC4), Ti-5Al-2. 5Sn (TA7) and industrial pure titanium (TAL, TA2 and TA3).
Titanium plates and strips are widely used, 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 devices. Titanium and titanium alloy plates and strips can also be used as fuel and oxidant storage tanks and high-pressure vessels.
