Black Silicon Carbide Specifications

  • Black Silicon Carbide sic is produced in a high temperature electric resistance-type furnace from a mixture of quartz sand and petroleum coke.
  • The hardness of black silicon carbide sic is greater than fused alumina but less than synthetic diamond.
  • Black silicon carbide’s mechancial intensity is greater than fused alumina, but is brittle and very sharp.
  • Black silicon carbide sic has some electrical and heat conductivity.
  • Black silicon carbide sic is typically used for machining or finishing cast iron ,non-ferrous metals, stone, leather, rubber, and other materials where sharp cutting characteristics are important.
  • Black Silicon Carbide sic is also used widely as a refractory material or metallurgical additive.

Black silicon carbide grit size and each Application

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-grit,P12-P2500,used for abrasive paper grit  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.
