Titanium Grade 2, Sheet, Bar, Plate, AMS 4902 (CP Grade 2) - UNS R50400
Commercially Pure or CP titanium is unalloyed. Grade 2 has higher levels of iron and oxygen than other CP grades, which offers excellent formability and moderate strength with superior corrosion resistance and is widely used in heat exchangers. Grade 2 titanium is one of the most common titanium grades, with properties that make it a good candidate for chemical and marine, aerospace and medical applications.
