WHITE FUSED ALUMINA FOR MATTE EFFECT SANDBLASTING
Full series of abrasive for bonded abrasives are available in our factory, including Black fused alumina, brown fused alumina, black fused alumina.
All these three abrasive can be used for bonded abrasives, here are differences among them.
| Abrasive/Difference | Color | Al2O3 | Hardness | Toughness | Application in bonded abrasives |
| White fused alumina 2810109000 | White | 99% | Highest | Not high, Brittle | Full WA abrasives, or mixed with BFA |
| Brown fused alumina 2810101000 | Brown | 95% | High | Good Toughness | Full BFA abrasives, or mixed with WA or BA |
| Black fused alumina 2818101000 | Black | 62% | Moderate | Best toughness | Using mixed with BFA |
| GRAIN SIZES AVAILABLE | |||
| 12#, 14#, 16#, 20#, 24#, 30#, 36#, 46#, 54#, 60#, 70#,80#, 90#, 100#, 120#, 150#, 180#, and 220# |
| Abrasive | Hardness | Toughness | Materials suitable for grinding
| Features |
| White fused alumina | Higher | Little Lower | precision hardened steel, high carbon steel, high speed steel and ground thin-walled parts. | When grinding, the abrasive particles are easily broken, so the grinding heat is small. |
| Brown fused alumina | High | High | grinding metals with high tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze, etc. | It has good grinding performance. Often used for rough grinding with large margin and widely used.
|
| Black fused alumina | Lower | Highest | carbon steel, alloy steel, malleable cast iron, | Adding15%-30% black fused alumina with BFA to produce cutting discs can improve work life and the incision quality and reduce production cost. |
