By organization
1. Aluminum and tin elements are added to titanium. 2. Alloying elements such as aluminum, chromium, molybdenum, and vanadium are added to titanium. 3. Elements such as aluminum and vanadium are added to titanium.) Titanium alloy has high strength and small density, good mechanical properties, toughness and corrosion resistance.
By blended elements
An alloy composed of titanium as a base and other elements. The industrial production of titanium began in 1948. The needs of the development of the aviation industry have led to the development of the titanium industry at an average annual growth rate of about 8%. The annual output of titanium alloy processing materials in the world has reached more than 40,000 tons, and there are nearly 30 kinds of titanium alloy grades. The most widely used titanium alloys are Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and industrially pure titanium (TA1, TA2 and TA3).
By application
Titanium alloys can be divided into heat-resistant alloys, high-strength alloys, corrosion-resistant alloys (titanium-molybdenum, titanium-palladium alloys, etc.), low-temperature alloys and special functional alloys (titanium-iron hydrogen storage materials and titanium-nickel memory alloys) according to their uses. The composition and properties of typical alloys are shown in the table.
