Titanium Grade 1, CP Gr.1

Titanium Grade 1(UNS R50250) is unalloyed and generally known as CP (Commercially Pure). It is the softest and most ductile grades of commercially pure titanium family with low oxygen. Titanium grade 1 possesses the greatest formability, excellent corrosion resistance and high impact toughness. It’s ideal in various manufacturing industries from aerospace, medical, shipping, military etc. LKALLOY mainly supplies Titanium Grade 1 tubing, Titanium Grade 1 sheet and Titanium Grade 1 round bar in various size and specifications.
