Products Description
Ti 3AI/2.5V (Titanium Grade 9) alloy is a near alpha, alpha-beta alloy, sometimes referred to as "half-6-4." It offers 20 to 50% higher tensile strength than the commercially pure titanium at room and elevated temperatures. It is much more amenable to cold working than Ti 6AI/4V alloy and can be cold worked 75 to 85% to result in moderately high strength and good ductility. Furthermore, it is weldable as the commercially pure grades and has excellent resistance to torsion and corrosion.Ti 6Al/4V 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. Amongst its many advantages, it is heat treatable.
Therefore, it is used principally as tubing in aircraft hydraulic systems and as foil in aircraft honeycomb panels. Its applications include aerospace parts, sport equipment, medical and dental implants.
