Extra Ordinary Properties of Titanium Useful in Various Sectors and Enlightenment of "The Kroll Process"

Abstract

Because of light weight, high strength to weight ratio, low modulus of elasticity, and excellent corrosion resistance, titanium and some of its alloys having important properties for the aerospace industry since the 1950s. Now, with the additional advantages of excellent biocompatibility, good local spot weld ability, and easy shaping and finishing by a number of mechanical and electrochemical processes, these materials are finding uses in dental applications, such as implants and restorative castings. Although more research is still needed in areas such as development of optimal casting investments, porcelain veneering systems, device designs, and controlled biological responses, the present and future uses of titanium appear bright for human implant. Titanium has high strength-to-weight ratio (434 MPa at density 4510 kg/m³), excellent corrosion resistance, and biocompatibility. Kroll process produces titanium sponge for aerospace and medical implants. Titanium has very high strength to weight ratio hence is widely used in aerospace sector and also in armor field. Because of light weight, high strength to weight ratio, low modulus of elasticity, and excellent corrosion resistance, titanium and some of its alloys have been important properties for the aerospace industry. This material is widely use in aircraft jet engines, Industrial gas turbines, Automotive industry, Computer industry due to its corrosion resistance.
