Titanium Grade 9 (3AL2.5V)

Titanium Grade 9 is a titanium alloy that offers an excellent combination of high strength, low weight, and good corrosion resistance. Primarily composed of titanium, aluminum, and vanadium, this alloy is ideal for applications that require strong mechanical performance without compromising on weight.
In addition, Grade 9 titanium has become extremely popular in industries such as aerospace and automotive due to its ability to withstand high mechanical stress. It is therefore successfully used in critical applications where reliability is essential.

The alloy also provides remarkable resistance to corrosion in both acidic and alkaline environments, making it well-suited for use in the chemical and marine industries. As such, it is an excellent choice for equipment operating in extreme environmental conditions.

Furthermore, Titanium Grade 9 stands out for its very good weldability and machinability, making it highly versatile in the production of complex structural components.
