WIWOX® SI Black silicon carbide
mineral − edged
Product description
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.
Suitable blasting processes
- Pressure blasting process
- Injection blasting process
Applications
- Grinding, lapping and polishing medium
- Reusable abrasive
