Titanium Main Applications

Titanium alloy has more applications in aviation, ships, automobiles, medical care, etc., limited by price, the application is not widespread enough. In the 1950s and 1960s, the main development of high-temperature titanium alloys for aircraft engines and structural titanium alloys for airframes. a number of corrosion-resistant titanium alloys were developed in the 1970s, and corrosion-resistant titanium alloys and high-strength titanium alloys have been further developed since the 1980s. Titanium alloys are mainly used to make aircraft engine compressor parts, followed by structural parts for rockets, missiles and high-speed aircraft. The Northwest Institute of Nonferrous Metals has developed flame-retardant titanium alloys, and the Institute of Metals of the Chinese Academy of Sciences and the Beijing Institute of Aeronautical Materials have also conducted research in this area. Titanium alloy in the humid atmosphere and seawater media work, its corrosion resistance is far better than stainless steel; pitting, acid corrosion, stress corrosion resistance is particularly strong; alkali, chloride, chlorine organic items, nitric acid, sulfuric acid, etc. have excellent corrosion resistance. But titanium has a reducing oxygen and chromium salt media corrosion resistance is poor. Baoji non-ferrous metal processing plant to develop Ti70 and the Northwest Nonferrous Metals Research Institute developed Ti91 has a good medium-strength high plastic, cold working properties, sound transmission properties and weldability. These titanium alloys have a wide range of applications in ships, submarines, submarine explorers. Automotive lightweight is one of the most promising markets for titanium. Titanium alloys are mainly used in automotive engine components such as connecting rods, springs, crankshafts, fasteners, etc. Titanium alloys are widely used in surgical implantation procedures. Representative titanium alloy Ti-12Mo-6Zr-2Fe is a substable alloy suitable for orthopaedic components due to its high strength and fracture toughness, wear and corrosion resistance and modulus of elasticity. Improving the mechanical properties, corrosion resistance and biocompatibility of titanium alloys with alloying elements Zr, Pd, Nb, Sn and Ta is the main way to develop biotitanium alloys.
