Product Description

   Bonded Abrasives White Fused Alumina / Aluminum Oxide Abrasive Media

1. Description of White Aluminum Oxide Fused Alumina Powder

White aluminum oxide is a high purity abrasive electrically fused from Bayer processed alumina. This material is classified to exacting standards for various applications where higher purity levels and reduced iron content are required.The crude grits 12#, 24#, 30#, 36#, 46#, 54#, 60# are widely used to produce Vitrified bonded abrasives grinding wheels and Resin bonded abrasives cutting discs, etc.. and also using for sandblasting.Sizing standard China GB/T, FEPA, JIS and ANSI are all available against clustomers' request.

• High Purity,good Stablility at high Temperature
• High Hardness, Wear-resistant
• Resistence to Acid & Akalid
• Good Electrical Insulation
• Thermal Conductivity
• Low Cost

Difference Brown Fused Alumina & White Fused Alumina in Bonded Abrasives Grinding Wheels As Below:

 

Abrasive	Hardness	Toughness	Materials suitable for grinding	Features
Brown Aluminum Oxide	High	High	grinding metals with high tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze, etc.	It has good grinding performance. Often used for rough grinding with large margin and widely used.
White Aluminum Oxide	Higher	Little Lower	precision hardened steel, high carbon steel, high speed steel and ground thin-walled parts.	When grinding, the abrasive particles are easily broken, so the grinding heat is small.

 

Difference Between Brown Aluminum Oxide and White Aluminum Oxide In Sandblasting As Below:

 

Abrasive	Using Difference in sandblasting
Brown Aluminum Oxide	When fast cutting is needed, with a reclaimable media, brown aluminum oxide is often the best value.
White Aluminum Oxide	White aluminum oxide boasts of a extremely high purity that makes it suitable for applications requiring minimum contamination of foreign substances and sharp free cutting abrasive characteristics.

7.Why Choose Us?

Now ,the raw material industry has come out vicious competition with price war in China . In order to get more profit ,  some suppliers think out many strange methods under upon Low price. For example, they add something which very cheap but the appearance is very similar with the goods. No one can find any difference via appearance. The consequence is that clients diffcult to get goods which have surprisingly good effect.I hope that more customers can avoid this kind of loss through my own efforts. Jointly create a good market order
