Overview

Unalloyed Commercially Pure (CP) Titanium is available in four different grades, 1, 2, 3 and 4, which are used based on the corrosion resistance, ductility and strength requirements of the specific application. Titanium Grade 2 is stronger than Grade 1 and equally corrosion-resistant against most applications.
