Product Description

Brown fused aluminaBrown fused alumina is also called brown corundum, is formed by melting and crystallization of high-quality raw materials such as bauxite and anthracite-based coke at high temperature. The main mineral components of brown corundum are physical corundum, trigonal crystal system, and mineral impurities are: calcium silicate, anorthite, mullite (also known as mullite), titanium compounds, glass body and iron alloys.

Physical properties of brown corundum:

Item	Indicators
Colour	Dark brown (dark blue after calcination)
Crystal shape	Triangular crystal system
Hardness (Mohs)	≥9.0
Melting point (°C)	2250
Maximum use temperature (°C)	1900
True density (g/cm3)	≥3. 90
Coefficient of linear expansion (0-1600°C)	7-9

Our Advantages

Advantages of White fused alumina:

1,High hardness and dense particles. Single particle roundness is good.
2, The color is pure white, no impurities, to ensure the wear-resistant layer or wear-resistant paper color and transparency.
3, Uniform distribution of particle size, single particle shape consistent, with a small amount of wear - resistant effect.
4, Chemical stability and acid, alkali no action, high temperature stability is very good.

Product Application

Sandblasting
Brown fused alumina has moderate hardness, high bulk density, no free silica, large specific gravity and good toughness. It is an ideal "environment-friendly" sandblasting material, which is widely used in aluminum profile, copper profile glass, precision
molds for washed jeans and other fields.

Making Abrasive
Brown fused alumina is used to make resin abrades or coated abrades. Abrasives have appropriate color, good hardness, toughness,appropriate particle cross-section type and cutting edge retention, which are applied to resin abrasives with ideal effect, and also widely used in sand paper, emery cloth factory.

Free Grinding

Brown fused alumina as grinding grade abrasive, which is used for free grinding in the fields of kinescope, optical glass,
monocrystalline silicon, lenses, watch glass, crystal glass, jade articles, etc., and is a widely used advanced grinding material.
