Brown aluminium oxide
Brown aluminium oxide has high toughness. Micro hardness is 1800~2200kg/mm2 Abrasive articles made of grinding metals of high─class refractory products. The raw material used is mainly bauxite. It is fused in an electric arc furnace of extreme high temperature. Processes of crushing, sifting and iron extraction then follow.
Characteristics:
- The most commonly used in artificial abrasives.
- In extensively used in sand blast.
- Hardness is high.
- The price is the most economical among the artificial abrasives.
- The efficiency of cutting is higher than quartz sand and glass bead.
Applications:
- Sand blast polish, burnish, zincograph polish, blowpipe sand blast, stained glass sand blast sculpture.
- Emery wheel, emery cloth, emerypaper, grindston, hard alloy that used to grinding, drossing agent of steek-making, and create hardness.
- Model, painting grind tools, friction pad rubber model, IC burr removal, bakelite burr removal.
Usage:
- Sand blast removal of rusty, removal of paint, and removal of black-spots.
- Removal of glue on the electronics components.
- Model texture and mist finish.
- The pretreatment of electroplate and spraying paint.
- The pretreatment of covering Teflon or rubber.
- Processing of surface roughness for artificial joint.
- Sand blast and pattern sculpture for flat glass.
- Mist finish processing on gold jewelry.
