APPLICTION:
Tungsten carbide (T.C.& W.C.) is a super material, main for mould and wear resisting application; currently we supply nickle and cobalt binder for our customers that used widely within high parameter seals.
PHYSICAL PROPERTY:
-- High hardness
-- Good wear resistance
-- High temperature resistance
-- Minor linear expansion coefficient.
-- Minor coeffcient of friction
TYPE AND PRODUCTS
--Type 1: Nickle binder.
-- Suitable medium: Oil, sewage, weak acid and alkali, grease, liquid hydrocarbon, strong alkali, and medium
containing particles, etc.
