Overview

CP-1, Commercially Pure Titanium, also known as Titanium Grade 4, is stronger than CP Grades 2 & 3 – it can be cold formed, but has lower ductility. It has excellent corrosion resistance in a wide variety of environments. Grade 4 titanium is most commonly applied in aerospace applications and chemical processing markets where high strength is needed. CP-1 possesses outstanding corrosion resistance and ductility. Due to its excellent resistance to corrosion fatigue in seawater, it is also commonly used for marine components.

This alloy is also very resistant to many chemical environments including oxidising media, alkaline media, organic compounds and acids, aqueous salt solutions, and wet or dry hot gases. It also has sufficient corrosion resistance in liquid metals, nitric acid, mildly reducing acids, and wet chlorine or bromine gas.

CP-1 has the highest strength of the CP grades, making it competitive with stainless steels for many corrosion resistant applications. While its strength is on a par with annealed stainless steels, it offers superior corrosion resistance and significantly lighter weight due to its low density.

CP-1 is not subject to grain boundary embrittlement or sensitization at elevated temperatures.
