Types of Abrasive Grains
1. Brown Fused Alumina
Brown Fused Alumina (BFA) is one of the most widely used abrasive materials. It is produced from bauxite and has a high degree of hardness, which makes it ideal for grinding and cutting applications. Its toughness also ensures that it can withstand severe conditions.
2. White Fused Alumina
White Fused Alumina (WFA) is characterized by its high purity and low magnetic properties. It is commonly used in precision grinding and other applications that require clean and consistent abrasives. The low impurities also make it suitable for ceramic applications.
3. Silicon Carbide
Silicon Carbide (SiC) is known for its extreme hardness and is often used in applications involving hard materials, such as glass and ceramics. Its high thermal conductivity also allows it to be used in demanding environments where heat resistance is a necessity.
4. Boron Carbide
Boron Carbide is one of the hardest materials available and is used primarily in armor applications and cutting tools. Its chemical resistance makes it suitable for harsh environments, while its hardness allows for effective cutting and grinding.
5. Fused Zirconia-Mullite
Fused Zirconia-Mullite is widely used in refractories and foundries due to its high thermal stability. This material can withstand extreme temperatures, making it ideal for applications where heat resistance is crucial.
