325mesh white fused alumina fine powder for sandblasting

 

Description

 

White fused alumina is made from high quality alumina by being melted above 2000°C in the

electric arc furnace. It is characterized by high purity, great self-sharpening, acid and alkali

resistance, high temperature resistance and stable thermal performance. Its hardness is a

little higher than brown fused alumina. It is with low toughness, great grinding ability, small heat

and high efficiency. White fused alumina can be made into all kinds of abrasives, suitable for

grinding high carbon steel, high speed steel, stainless steel and other fine-grained abrasives.

 

Performance and advantages

 

1. Not affecting the color of the processing cases

2. Sandblasting in the non-iron process

3. Powder level ideal for wet blasting and light lapping

4. High speed process and quality

5. Containing a very low amount of iron oxide, suitable for non-ferrous blasting operations

6. After acid washing steps

 

Application

 

1. Available research in a variety of blasting and light lapping operations

2. The process of beautifying glass or acrylic

3. The process of blasting TV screens

4. The cutting of silicon wafer

5. The process of cleaning and blasting tooth model

6. Precision sand casting

7. High refractory and other ceramic additives
