 All of the Spears Titanium products are Grade 5, also known as Ti6Al4V, Ti-6Al-  4V or Ti 6-4, is the most commonly used alloy. It has a chemical  composition of 6%  aluminum, 4% vanadium, 0.25% (maximum) iron, 0.2% (maximum) oxygen, and the  remainder titanium.[7] It 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 Ti than in CP Ti). Among its many  advantages, it is heat treatable. This grade is an excellent combination of strength,  corrosion resistance, weld and fabricability.
