TC21 TC21 titanium alloy TC21 titanium bar Titanium TC21 TC21 TC21 hardness density
Titanium TC21; a contemporary titanium aircraft and engine major structural materials. Mainly for the manufacture of aerospace aircraft structural parts. TC21 is a high strength, high toughness, damage tolerance type α + β two-phase titanium alloy. The alloy has excellent strength, ductility, toughness and low crack growth rate.
With the development of science and technology, the conversion of the production structure, TC21 Titanium also made into the civil aerospace plays an unparalleled role in many modern industries in many wear-resistant, high temperature, high strength, high toughness of machinery, products , equipment used in the field of materials has also been widely used. It may be higher than the hardness of titanium TC 110 degrees (Rockwell), can reach between 130-150 degrees. Its abrasion resistance has also been reflected by customers refer to the ultrasonic detection probe production areas.
