Product Description

Moderate Hardness Black Aluminum Oxide Artifical Corundum F100#-F400# for Fiber wheels

1. Product Description of Black Aluminum Oxide Artifical Corundum

Black aluminum Oxide is one kind of flexible wear-resistent abrasive,it has the characteristic of moderate

hardness and good self-sharpness, which is generally mixed with brown fused alumina to make bonded

abrasives and coated abrasives for polishing and cutting purpose.

3. Main Applications of Black Aluminum Oxide Artifical Corundum

Black Aluminum Oxide is suitable to make verious coated abrasives such as fiber wheels,nylon sand belts,

sponge sand blocks, scouring pad.

4. How to use Black Aluminum Oxide Artifical Corundum to Make Coated Abrasives?

One application is use the pure black aluminum oxide to make the above products for polishing various

workpieces especially for stainless steel polishing.

When making the above products,It is suggested to increase the ratio of black aluminum oxide and use more

coarse grain size to enhance the final durability.

The other application is mixing black aluminum oxide with other higher hardness and durability abrasives such

as brown alumium oxide,silicon carbide to make the above products.Then it will with other higher hardness

and durability abrasives such as brown alumium oxide,silicon carbide.

It is suggested to use more coarse black alumina grit to partly replace the original grit of brown alumina or

silicon carbide,then maintain the other grit size as the original one.

The specific mixture ratio could be achieved by experience.
