Titanium is a very abundant element inthe earth whose resources reserves is in the fourth largest place only less than that of iron,aluminum and magnesium.It is a kind of light metal in grey metallic luster and of unique comprehensive characters such as low density,high specific strength,excellent corrosion resistance,low thermal conductivity,good superconductivity,excellent elasticity,high damping and outstanding properties of shape memory,surface modification,hydrogenocclusion,biocompatibility,etc.,and thus widely applied in oil,chemicals,energy,metallurgy,light industry,pharmacy,salt-making,ocean engineering,architectural decoration,automobile manufacture,sports and leisure,and other fields.
