company news about Brown Fused Alumina VS White Fused Alumina

Brown fused alumina (BFA) and white fused alumina (WFA) are both popular materials used in the production of refractory products, but they have some key differences in their properties and applications.

1. Color: The most obvious difference between BFA and WFA is their color. BFA is a dark brown color, while WFA is white.

2. Hardness: BFA is slightly harder than WFA, making it better suited for applications where resistance to abrasion and wear is important.

3. Melting point: BFA has a slightly lower melting point than WFA, making it less suitable for high-temperature applications.

4. Impurities: BFA contains higher levels of impurities than WFA, including iron oxide and titanium oxide. This can make BFA less suitable for certain high-purity applications.

5. Price: BFA is typically less expensive than WFA, making it a more cost-effective option for many applications.

6. Applications: BFA is commonly used in the production of abrasive materials, such as grinding wheels and sandpaper, as well as in the production of refractory products. WFA is often used in the production of high-purity ceramics and other applications where a white or light-colored material is required.
