How to Select the Right Silicon Carbide?​

​

Choosing the right ​​silicon carbide (SiC)​​ depends on ​​material hardness, precision needed, and application type​​.

 

​​Factor​​
​​Green SiC (Recommended For)​​
​​Black SiC (Recommended For)​​
​​Workpiece Material​​
- ​​Tungsten carbide, ceramics, glass, hardened steel​​.
- ​​Cast iron, steel, non-ferrous metals (aluminum, brass)​​.
​​Required Finish​​
- ​​High precision, fine polish, mirror finish​​.
- ​​Rough grinding, fast material removal​​.
​​Abrasion Resistance​​
- ​​Better for ​​hard, brittle materials​**​.
- ​​Better for ​​tough, ductile metals​**​.
​​Cost​​
- ​​More expensive (higher purity)​​.
- ​​Cheaper (more widely available)​​.
​​Grinding Type​​
- ​​Lapping, fine grinding, polishing​​.
- ​​Coarse grinding, cutting, rough machining​​.

 

​​Selection Guide:​​

✔ ​​For precision & hard materials → Green SiC​​.
✔ ​​For rough grinding & tough metals → Black SiC​​.
