Titanium Grades 1-4 are unalloyed and generally known as CP (Commercially Pure). The tensile and yield strength of titanium generally increases with the grade number. Titanium is 30% stronger than Steel but nearly 50% lighter and although Aluminium is lighter, Titanium is stronger and has excellent strength retention. Due to Titanium's weight, strength and high corrosion resistance it is very popular in various manufacturing industries from aerospace, medical, shipping, military etc.
