White Fused Alumina
White fused alumina powderis 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.
White fused alumina properties
Characteristics
White fused alumina has the characteristics of moderate hardness, good self-sharpening, wear resistance and stable chemical properties. Suitable for abrasives, industrial chemicals and refractory materials.
Faqs of White Fused Alumina
What is the difference between white and brown fused alumina?
Application: White fused alumina hs codeis 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.
Do you add boric acid during smelting?
What's the sodium content of your white fused alumina?
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%
