Product detail:

BLACK CARBORUNDUM

 

1. Higher hardness than corundum and less than diamond.
2. Mechanical strength is higher than corundum.
3. Sharp, brittle, fragile, low expansion coefficient, and with good electric conductivity.

 

 

    Black carborundum, also called black silicon carbide ( C ), is widely used to make coated or bonded abrasives , refractory, special ceramics, foam ceramic , etc. .

    Black carborundum also used for coating plastics additives, auto parts, military industry products, aviation industry products, etc.

    The workable material by silicon carbide:

ü  Low tensile strength material, for glass, china.

ü  Sandblasting, dry grinding, free grinding as well as cutting and making jewelry, jade, agate.

ü  Grinding of gray cast iron, white cast iron, bronze, brass, ore, bone, glass, leather, rubber, plastic and the thermal sensitive material.

 

 

    The company specializes in manufacturing high quality black carborundum ( C ) ,the types are F-series(F12--F220) , P-series(P12--P220) , JIS-series(JIS320—JIS10000) . We manufacture top-grade C (sic content--98.5%) , second grade C (sic content--90% ) , magnetic sand , etc..
