Description:
1.Manufacture for over 30 years2.High purity and nice grit distribution
3.Owning refining furnace
1. PolishingAbrasive aluminum oxide al2o3 / abrasive grade white fused aluminumoxide products
Whitefused aluminium oxide is electrically fused in the furnace withhigh-grade alumina powder as raw materials. It has higher hardnessand slightly lower toughness than brown fused aluminium oxide ,characte-rized by its high purity, strong grinding ability,Abrasives tools made of it are suitable for grinding high speedsteel, etc. It also can used as materials for grinding andpolishing precision-casting, spraying and coating, medium body forchemical industry, special ceramics and high-grade refractorymaterials , etc.

3.Company Brief:
Zhengzhou Yellow River (ZYR) Abrasives Co. Ltd , which was founded in 1976, is a main manufacturer in China
We supply Black/Green Silicon Carbide, White/Brown Fused Aluminum Oxide.
The production and quality are in accord with GB, ISO, JIS, Standard or conform to specific request.
4. Applications:
1. grinding high carbon steel, high-speed steel and chilled steel.
2. lapping and polishing medium, precision founding sand, coating materials, special ceramics and super refractory materials.
5. Advantages:
(1) Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities.
(2) Good hardness, longer life.
(3) Chemical washed and water washed good cleanness.
(4) Special treated products get higher purity, better toughness, and better grinding effect.
Other special specification and other standard graded powder is available on
request.
