Ceramic Alumina Abrasive powder F240-F600
Introduction of Ceramic Alumina Abrasive powder F240-F600
Ceramic Alumina Abrasive powder F240-F600 is made by sol-gel process. Ceramic abrasives powder is extremely hard and durable compared to traditional aluminum oxide abrasive materials. It is suitable for bonded grinding tools and coated grinding tools.
Ceramic Alumina powder is particularly used for casting steel grinding under high pressure, as well as precision grinding of various materials, including gear grinding, bearing grinding, crankshaft grinding, rolling mill grinding, and others.
The features of Ceramic Alumina Abrasive powder:
- Tiny crystal size of nano size. That caused sharp grinding and less sparkle.
- Excellent self-sharpening performance.
- High hardness
- Extreme high toughness.
