TIMETAL 75A is equivalent to ASTM Grade 4. It has the highest strength of the four ASTM commercially pure titanium grades in addition to good ductility and moderate formability. The benefits of the good strength to weight ratio of TIMETAL 75A are retained at moderate temperatures. TIMETAL 75A is typically used in continuous service up to 800°F (425°C) and in intermittent service up to 1000°F (540°C). It also has good impact properties at low temperatures. In addition, TIMETAL 75A can be satisfactorily welded, machined, cold worked, hot worked, and cast.
