Gr7 titanium rods in the use of what standards? alpha alloy contains a certain amount of stable α-phase elements, the equilibrium state is mainly composed of α-phase. alpha alloy specific gravity is small, good heat strength, good weldability and excellent corrosion resistance, the disadvantage is the room temperature strength is low, usually used as a heat-resistant and corrosion-resistant materials. alpha alloy is usually subdivided into full-alpha alloys (TA7), near-alpha alloys (Ti-8Al-1Mo- 1V) and alpha alloys with a small amount of compounds (Ti-2.5Cu). 1V) and alpha alloys with a small amount of compounds (Ti-2.5Cu).
