Product Details

Brief Introduction of Brown Fused Alumina

The main raw material of brown fused alumina is high quality bauxite, which is fused with the carbon material and scrap iron in the electric furnace under the high temperature of above 2200℃. The product is characterized by low expansion coefficient, high refractoriness, good thermostability and chemical stability.

Application:

1. Bonded abrasives like Grinding wheels, etc.

2. Sandblasting

3. Ceramics

4. Coated abrasives

5. Cutting wheels

6. Polishing materials

8. Precision casting

Properties of high temperature calcinated brown fused alumina

1. The impurities in the abrasive is precipitated or vaporized under high temperature.

2. Purer abrasive improves the hydrophility.

3. Refines the cracks; Greatly improves the toughness, strength and performance of abrasive.

4. Modifies the appearance of abrasive tools.
