Short Description

Grade 5 Titanium (Ti-6Al-4V) Strip*, Coil*, Foil*, Wire, ASTM B265

Description

Ti 6-4 (Grade 5) is significantly stronger than commercially pure titanium while having the same stiffness and thermal properties (excluding thermal conductivity, which is about 60% lower in Grade 5 than in CP Ti). Among its many advantages, Grade 5 Titanium it is heat treatable. This grade is an excellent combination of strength, corrosion resistance, weldability and fabricability.
