White Fused Alumina

White Fused Alumina is made of high-quality alumina powder as raw material,which is refined and crystallized by electrofusion.


Product introduction 

The characteristic of white fused alumina:


1.Its hardness is slightly higher than that of brown fused alumina,

2.its toughness is slightly lower.

3.High purity,

4.Good self-sharpening,

5.Strong grinding ability,

6.Low calorific value,

7.High efficiency,

8.Acid and alkali corrosion resistance,

9.High temperature resistance 

10.Stable thermal performance


Application:


1. Used to make abrasive tools ,

2.Grinding high-carbon steel,

3.High-speed steel,

4.Stainless steel 

5.Other fine-grained abrasives, 

6.Precision casting 

7.Advanced refractories.
