Silicon Carbide Abrasive Characteristics

Hard, Sharp and Brittle Grain Behavior

• High hardness and sharp cutting edges
• Brittle fracture exposes fresh cutting points
• Not suitable for heavy impact loads

 

————————————————————————————————————————————————————————————————————————————————————

Low-Pressure Processing Logic

Precision over Aggression

Silicon carbide belts perform best under low tension and low feed pressure, prioritizing surface quality over aggressive material removal.

Backing & Machine Compatibility

Stability for Fine Finishing

• X-weight cloth backing: Suitable for medium-speed precision grinding
• Light cloth / paper backing: Ideal for low-pressure fine finishing
