Titanium alloys are commonly divided into three groups according to the type of crystal structure: 1. Ti with Al, Sn; 2. Ti with Al, Cr, Mo, V; 3. Ti with Al, V. They have good mechanical and punching properties and can be welded by various forms of welding procedures with welded joint strength up to 90% of base metal. Titanium is capable of corrosion resistance to chlorides, sulfides and ammonia, and has better corrosion resistance than aluminum, stainless steel and nickel alloy for seawater service.
Grades：Grade1, Grade2, Grade12, Grade16 etc.
