BlACK SIC SILICON CARBIDE F280
Black SiC is also called black silicon carbide ,black carborundum,which is made from silica sands and petroleum coke.
Zhengzhou haixu abrasives co.,ltd,founded in 1999,has been producing and exporting silicon carbide for more than 20 years,the normal sizes we produce are:
