CP Titanium = commercially pure (unalloyed) Titanium.
CP Titanium is classified in different grades. These grades are distinguished by their varying degrees of tensile strength and ductility, as a function of oxygen content.
Grade 1 is the most ductile material with lowest tensile strength.
Grade 4 is the least ductile material with highest tensile strength.
Element 22 can mold product in grades 1, 2 & 3.
