Classification, properties and applications of titanium alloys

Titanium and titanium alloys have good welding, hot and cold pressure processing, and machining properties, and can be processed into various titanium profiles, titanium rods, titanium plates, and titanium pipes for supply. Titanium is an ideal structural material. The density of titanium is only 4.5g/m3, which is 43% lighter than steel, but its strength is twice that of iron and almost five times that of pure aluminum. It has a low density and high strength properties. This combination of high strength and low density makes titanium rods occupy an extremely important position in technology. At the same time, the corrosion resistance of titanium alloy rods is close to or exceeds that of stainless steel, so it has been widely used in the petroleum, chemical industry, pesticides, dyes, papermaking, light industry, aviation, space development, marine engineering, etc. Titanium alloys have high specific strength (ratio of strength to density). Titanium Flat Washer DIN 125 alloy rods and pure titanium rods have played an irreplaceable role in aviation, military industry, shipbuilding, chemical industry, metallurgy, machinery, medical treatment, and other fields. For example, the alloy composed of titanium and aluminum, chromium, vanadium, molybdenum, manganese, and other elements, after heat treatment, the strength limit can reach 1176.8-1471MPa, and the specific strength can reach 27-33, and the alloy steel with the same strength has only 15.5 -19. Titanium alloys are not only high in strength but also resistant to corrosion, so they are widely used in shipbuilding, chemical machinery, and medical equipment. Among them, corrosion-resistant titanium alloys are mainly used in reactors, towers, autoclaves, heat exchangers, pumps, valves, centrifuges, pipes, fittings, electrolyzers, etc. in various highly corrosive environments. However, due to the high price of titanium alloys, their application is limited.
