Titanium alloy classification characteristics and applications

Titanium alloys can be divided into structural titanium alloys, heat-resistant titanium alloys, corrosion-resistant alloys, cryogenic alloys, and special function alloys (memory alloys, superconducting alloys, hydrogen-storage alloys) and so on.

According to the strength of titanium alloys, there are low strength titanium alloys, ordinary strength titanium alloys, medium strength titanium alloys and high strength titanium alloys.

Low-strength titanium alloys are mainly used for corrosion-resistant titanium alloys, while other titanium alloys are used for structural parts called structural titanium alloys (structure titanium alloy).

Ordinary strength titanium alloys (~ 500MPa), mainly including industrial pure titanium, Ti-2Al-1.5Mn (TCl) and Ti-3Al-2.5VTA18), is a widely used alloy. Due to good molding performance and weldability, they are used to manufacture various aerospace plate parts and hydraulic hoses, as well as civilian products such as bicycles.

Medium strength titanium alloys (~900MPa), typically Ti-6Al-4V (TC4), are widely used in the aerospace industry.

High-strength titanium alloy is room temperature tensile strength of 1100MPa or more, by nearly β titanium alloy and sub-stabilized β titanium alloy, mainly used to replace the aircraft structure of the commonly used high degree of structural steel, its typical alloy has Ti-13V-11Cr-3Al, Ti-15V-3Cr-3Al-3Sn (TB5) and Ti-10V-2Fe-3Al.
