CP Titanium = commercially pure (unalloyed) Titanium.
Element 22 manufactures MIM parts made from CP 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 being the most ductile material with lowest tensile strength.
Grade 4 the least ductile material with highest tensile strength.
