Product Description

Product Description

Brown fused alumina (BFA) is a high-quality synthetic abrasive material made from the fusion of bauxite and other materials in an electric arc furnace at high temperatures. It is one of the most widely used abrasives due to its excellent grinding and cutting properties.
Brown fused alumina has a deep brown color and its unique crystal structure gives it high toughness, durability, and resistance to wear and tear. It is widely used in the manufacturing of abrasive tools, grinding wheels, sandpaper, and other abrasive products.

Brown fused alumina is also used in various applications such as surface preparation, deburring, descaling, and polishing of various materials including metals, ceramics, and composites. Its properties make it an excellent choice for use in industrial applications where high levels of abrasion resistance and hardness are required.
Overall, brown fused alumina is a versatile and highly effective abrasive material that offers exceptional performance and durability in a range of applications, making it a popular choice among manufacturers and industrial users.
 

Advantages Of Brown Fused Alumina: 

1. Large crystal, high strength, good toughness, dense texture, high bulk density.

2. Stable performance between batches.

3. The higher grinding efficiency and polishing brightness, the grinding efficiency is much higher than the soft abrasives such as silica.

4. Good particle appearance, high surface finish of the polished object.
