--Reaction bonded silicon carbide (SISIC)
--Pressureless bonded silicon carbide (SSIC)
--Silicon carbide plus 30% carbon (SIC + CAR.)
--Pressureless bonded silicon carbide (SSIC)
--Silicon carbide plus 30% carbon (SIC + CAR.)
APPLICTION:
Silicon carbide is one of best material within the secondary frictional material and is applied for high-temperature equipment, wear-resisting parts of pump valve, automobile, astronavigation, shipping etc.
PHYSICAL PROPERTY:
-- Mach inability of blank
-- Availability of complicated products
-- High impact resistance
-- High hardness
-- Strong corrosion resistance
-- Minor frication coefficient
