Titanium carbide powder,Chemical formula TiC,Molecular weight 59.91,Carbon content 20.05%,Density 4.93g/cm3, Melting point:3160ºC,Boiling point 4300ºC.Titanium carbide is off-white powder with cubic system structure of NaCl type．The carbide is mainly used in preparation of cermet，heat-resistant material and cemented carbide due to its high melting point ,hardness and chemical stability. The wear-resistance,corrosion resistantce and resistance to oxidation of hard alloy can be improved clearly when TiC（6~30%）is mixed in WC-Co cemented carbide and form TiC-WC solid solution with WC．It is more suitable to process steel products．Also we can produce cemented carbide without tungsten using Ni-Co alloy to enhance the cutting speed and precision and smoothness of processed component．
