black Silicon Carbide with ISO9001 Certificate

black Silicon Carbide with ISO9001 Certificate

Black silicon carbide: Black Silicon Carbide in abrasives and refractory is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw marterials .Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina .It is brittle and sharp has electrical and heat conductivity in some degree.The abrasives made of it are suitable for working on cast iron,non-ferrous metal,rock, leather,rubber,etc.It is also broadly used as refractory material and metallurgical additive.

F12-F14,use for sandblasting,rust removal,snagging,heavy duty grinding of steel ingot,leather,salt,floor boards.
F14-F30,use for casting play burr,cutting billet and steel tube,flat kibbling,steel ingot grinding,marble grinding,or as refractory material.
F30-F60,use for surface abrasion,outside&surface grinding,centerless grinding,tool grinding of quenching or no-quenching steel profiles,copper or other hard metal.
F60-F100,use for precision grinding, cutter sharpening,gear grinding,etc.
F100-F240,use for cutter sharpening,rough grinding,precision grinding,thread grinding.
F280-F600,use for precision grinding&thread grinding of instrument and matter an gear products.
F600-F2000,super-precision polishing,mirror polishing,surface lapping,etc.
P-git,P12-P2500,used for coated abrasives products,outstanding advantages compared to F-grit is the More concentrade grit distribution of the basic grain,narrow grain span than F-grit
