Ti Beta C™
The Ti-3Al-8V-6Cr-4Zr-4Mo alloy is a heat-treatable beta titanium alloy. It exhibits good ductility in the annealed condition. After annealing and aging, it also possesses high strength and toughness properties. The fatigue strength is significantly high in the annealed and aged condition. °It is suitable for long-term use at temperatures up to 349°C.
