COMMERCIALLY PURE (CP) TITANIUM - GRADE 2 • UNS R56400 • WNR 3.7124

Commercially Pure (CP) titanium is an unalloyed titanium grade with a close-packed hexagonal (CPH) crystal structure at room temperature known as alpha phase structure. It has good formability, weldability, ductility, and corrosion resistance combined with moderate strength.

Grade 2 titanium has slightly increased higher mechanical properties when compared to Grade 1.

It is used principally in aerospace, automotive, chemical plants, marine environments, architecture structures & medical applications.
