company news about White Fused Alumina Properties

White fused alumina (WFA) is a high-grade abrasive material that is widely used in various industrial applications. Some of the key properties of WFA include:

1. Hardness: WFA is a very hard material, with a Mohs hardness of 9. This makes it an excellent abrasive material that can be used for grinding and cutting hard materials such as metals and ceramics.

2. High melting point: WFA has a very high melting point, typically around 2,050°C. This property makes it ideal for use in high-temperature applications such as refractory linings for furnaces and kilns.

3. Chemical stability: WFA is chemically inert, meaning that it does not react with most substances. This property makes it suitable for use in harsh chemical environments, such as in the manufacture of chemicals and pharmaceuticals.

4. Low thermal expansion: WFA has a low thermal expansion coefficient, which means that it does not expand or contract significantly with changes in temperature. This property makes it ideal for use in precision engineering applications where dimensional stability is critical.

5. High purity: WFA is typically very pure, with a minimum purity level of 99.5%. This property makes it suitable for use in high-tech applications such as semiconductors and electronics.
