Mineral − Edged

Product description

Technical data

The extreme hardness and angular yet sharp-edged properties is typical of black silicon carbide type WIWOX® SI. It is particularly suitable to machine hardened steel and ceramics. It consists of crystalline silicon carbide, which is produced from silica sand and petroleum coke in electric resistance furnaces at temperatures of > 2.300° C. Silicon carbide is iron-free, angular and extremely hard.
