White Fused Alumina

White fused alumina powder is made of industrial alumina powder, which is smelted in an arc at a high temperature of over 2000 degrees and then cooled. It is suitable for the manufacture of ceramics, resin-bonded abrasive tools, grinding, polishing, sandblasting, precision casting etc.

What is the difference between white and brown fused alumina?
-
Application: White fused alumina is used by the customers who are more pursuit of quality. It has a good polishing effect and is mostly used in carbon steel, alloy steel, malleable cast iron, hard bronze, etc. Brown fused alumina is widely used in the market.

Hardness: The hardness of white fused alumina is slightly higher than that of brown fused alumina.

Smelting: Brown fused alumina is made by melting bauxite at high temperature and is made by redox reaction. White fused alumina is made of high-quality alumina powder. Refining and crystallization of white fused alumina by electrofusion. High purity, good self-sharpening, acid and alkali resistance, corrosion resistance, high temperature resistance, stable thermal performance.

Purpose: White fused alumina: mostly used in high-end industries. It has a strong cutting force, is used to remove metal or non-metal burrs, has a polishing effect on the surface grinding of parts, and is a medium polishing abrasive.

Brown fused alumina: mostly for mass users, used to remove burrs on the surface of metal parts such as stainless steel, carbon steel and aluminum alloy.

Alumina content: white fused alumina: alumina content is 99.4%, Mohs hardness is 9.0. Brown fused alumina: alumina content of 95%, Mohs hardness of 8.9.

Color: white fused alumina: white and transparent. Brown fused alumina: brown-black, brown-red.

How is white Fused Alumina made?
-
White fused alumina is made from industrial alumina powder, which is smelted in an arc at a high temperature of more than 2000 degrees and then cooled. It is suitable for the manufacture of ceramics, resin-bonded abrasive tools, grinding, polishing, sandblasting, precision casting, etc. It can also be used to manufacture high-grade refractory materials. The code "WA" is consistent with international general standards and national standards.

Three kinds of white fused alumina are available:

White fused alumina with Na2O 0.2%

White fused alumina with Na2O 0.3%

White fused alumina with Na2O 0.4%
