Description
Grade 4 is known as the strongest of the four grades of commercially pure titanium. It is also known for its excellent corrosion
resistance, good formability and weldability.
Though it is normally used in the following industrial applications, Grade 4 has recently found a niche as a medical grade titanium.
It is needed in applications in which high strength is required .
