Product Description

Production description

Zirconia Alumina P-Grit For Polishing wheel

Fused Zirconia abrasive grain is produced by putting rich aluminum, zirconium materials and additives in electric furnaces, smelting with high temperature above 2000°C, cooling down with special technology, and compacting with Barmac plastic, which has the characteristics of excellent self-sharpening ability, tenacious texture, dense structure and high strength.

Why Adopting Zirconia grain for abrasive tools instead of Aluminum oxide?

The significant characteristics of Zirconia grain are as below:

1.High toughness can increase the lifetime of abrasive cutting disc & grinding disc.

2.High self-sharpening ability can make cutting disc& grinding disc sharper.

Applications

Making zircon fused alumina brick and building materials.
Used for making bonded abrasives products,and processes of grinding, sandblasting, surface treatment of metal products and other materials.
With good melt erosion resistance, Zirconia fused alumina has good grinding effect on steel, iron casting, heat resistant steel, and other alloy materials.
Fused Zirconia abrasive grain can be made for heavy-duty Zirconia fused alumina grinding wheel, snagging,cutting disc, Fiber disc, grinding rails, high-speed abrasive belts etc.
Used for making coated abrasives products.
Used for making lapping paste, polishing wax, emery cloth, sandpaper etc.
Crusher wear-resistant hammer head
