Product Description
  High Purity 99.5% White Fused Alumina For Sandblasting And Abrasive Tools

White fused alumina (WFA) belongs to the group of electro-corundum. The main material of WFA is a-Al2O3. It is a synthetic mineral of high purity and extreme hardness. Compared with brown fused alumina (BFA), White Corundum is harder, and it is more fragile.White Corundum is widely used in producing abrasive tools and refractory. Other applications include surface treatment, ceramic tiles, anti-skid paints, skin and dental care, etc..

Description

  • sandblasting aluminum oxide is made from bauxite, carbon materials, iron filings as raw material through melting in the electric furnace. 
  • It suitable for grinding high tensile metal, such as: a variety of common steel, malleable iron and hard bronze, etc., can also create advanced refractory

Advantage

  • high purity
  • good crystalline and liquidity.
  • low coefficient of linear expansion.
  • corrosion resistance.
  • not detonate, not powder, not crack

Parameter

      Knoop hardness: 2000 - 2200 Kg/mm2

  • Mohs hardness: 9.0
  • Density: 3.90 g/cm3
  • Melting point: 2500°C
  • Max temperature: 1900°C
  • Specific heat: (Cal/g. °C ) 0.26 (20 - 90°C  )
  • Refractive index: e=1.760 w=1.768(Na line)
  • Coefficient of linear expansion:  7 - 9 (0 - 1600°C)
  • The chemical composition : AL2O3Fe,Si,Ti

Usage

  • sandblasting aluminum oxide :sandblasting abrasive, moderate hardness, high bulk density, no free silica, heavy, good toughness, is the ideal "green" blasting material, widely used in aluminum, copper  type glass, washed jeans precision molds and other fields.
  • Freedom grinding - abrasive materials, is used screen tubes, optical glass, silicon, lenses, watches glass, crystal glass, jade and other areas, is a senior abrasive materials commonly used in domestic.
  • Resin Abrasives - Abrasive have the right color, hardness, toughness, suitable particle cross-section type and edge retention, used resin abrasive with the desired effect.
  • Coated Abrasives - the raw materials of abrasive sandpaper, abrasive cloth and other products.
  • Corundum functional fillers- for automotive brake parts, special tires, special construction products, also the construction of motorways, runways, terminals, parking lots, industrial flooring, sports ground and so on as resistance materials.

Now ,the raw material industry has come out vicious competition with price war in China . In order to get more profit ,  some suppliers think out many strange methods under upon Low price. For example, they add something which very cheap but the appearance is very similar with the goods. No one can find any difference via appearance. The consequence is that clients diffcult to get goods which have surprisingly good effect.I hope that more customers can avoid this kind of loss through my own efforts. Jointly create a good market order
