Higher hardness Brown Aluminum Oxide Emery Powder 95% Al2O3
F70#-F220# for Polishing
1. Product Description of Brown Aluminum Oxide Emery Powder
Brown Aluminum Oxide is also named as brown fused alumina, it
selects the high-quality bauxite,coke
(anthracite) as main raw materials, melting in an electric arc
furnace at a temperature over 2200℃,then
made into different grain size through cooling crystallization,
sort, crush, magnetic separation , screen size,
blow cleaning etc...
It has wide applications,which is called as the teeth of industry.

3. Main Features of Brown Aluminum Oxide Emery Powder
- High Hardness High Toughness
Brown aluminum Oxide contains at least 95% Al2O3,it has the high
hardness of Mohs 9,
Its special crystallization offers high toughness,it is suitable
for polishing purpose
Brown aluminum Oxide has lower fragility,it will not break down
easily,then it is more durable and could
be reused up to seven times.
Its high purity will not transfer ferrous contamination to the
treatment
Its good chemical stability will not cause chemical reaction to the
treatment, as well as no corrosion
or rust.
4. Main Application of Brown Aluminum Oxide Emery Powder
Brown Aluminum Oxide fine grain is widely used for polishing
various workpieces of iron, stainless steel,
white iron,then remove the surface burrs,overflap,oxide layers etc.
In addition,it is also used for surface preparation,anti-skid
materials,blasting&lapping media,making boned
abrasives& coated abrasives,high grade refractories etc.
