Product Description

Description:

Pink Fused Alumina, also called Pink Fused Aluminum Oxide, Chromium Aluminum Oxide, or ruby fused alumina, abbreviated as "PA". It is a kind of artificial corundum produced by adding chromium oxide to high purity aluminum oxide during the fusion process to get a pink color alumina. The amount of chromium oxide added affects the color of the final product, as well as the toughness of the grain. With increased additions of Cr2O3 to Al2O3,toughness and self-sharpening ability get increased and friability get decreased comparing with white alumina. So it can well balance the sharpness and life time with applications.

Defined with chromium oxide percentage, HAIXU Abrasives provide 3 types: Low chromium PA, Medium chromium PA, high chromium PA.

Characteristic:

1. Pink Fused Alumina is a kind of pure abrasive (Al2O3 purity 96.5-99%)
2. High toughness and self-sharpening
3. High hardness with sharp edges of crystals.
4. Durable, hard and resists high pressure
5. High abrasive resistance
6. It does not contain iron under normal conditions
7. It has a structure suitable for wet and dry sandblasting applications

Applications

1. Precision bonded abrasive tools such as Super-thin cutting disc, Cut off wheel, Grinding Wheel.
2. Ceramic grinding wheel such as Crankshaft Grinding Wheel ,bowl grinding wheel, Cup grinding wheel, Mounted Points, Vitrified Abrasive tools.
3. Coated Abrasive tools such as Sanding paper, Polishing Wheel.
4. High quality Refractory bricks.
5. Sandblasting, rust removal with aggressive blasting is required.
6. Lapping, polishing for extremely hard materials.
7. Technical Ceramics.
