Black fused alumina is also known as low alumina corundum. And it
is a dark gray crystal body madeα-AL2O3 and ferropicotite as
main ore in the electric arc furnaceby smelting the
bauxite.
Black
fused alumina is characterized by lowAL2O3 and a certain amount
of Fe2O3 (*0% more or less) content. So it has characteristics of
moderade hardness, high toughness, high temperature resistance,
and stable thermal stability. It is mainly suitable for free
grinding, such as coarse grinding before electroplating products,
mainly for polishing and sandblasting of stainless steel,
fabricated metal products, optical glass, bamboo products, and it
is also new abrasive for manufacturing resin grinding wheels,
cut-off wheels and emery cloth. The black fused alumina of the
company concentrated basic tablets, with the characteristics of
strong cutting power, high toughness, high flexibility, good
abrasion resistance and high working efficiency, which is the
best product for grinding and polishing, sandblasting stainless
steel products.
