Introduction

Titanium is a lustrous metal with a silver color, low density and high strength. It is as strong as steel and twice as strong as aluminum. When it is alloyed with other metals such as nickel, ruthenium, zirconium, vanadium, and aluminum, titanium alloys with unique properties are formed.
