1. Product Description of Aluminum Oxide Black Fused Alumina
Black Aluminum Oxide also belongs to the group of electric corundum,it is made by high iron bauxite, high
alumina bauxite and iron oxide as main raw materials,then smelted in the electric arc furnace completely, then
made into different grit size after different processes of cooling,crushing ,screening etc.It has the characteristics
of moderate hardness,good self-sharpness,strong cutting force,not easy to burn the treatment and low cost.

3. Why black aluminum oxide has the outstanding advantages in polishing stainless steel Tableware?
Seen from the micro-structure of aluminum oxide,the alumina particles has the main grinding and polishing
effect,it is dispersed in micro-crystalline state,surrounded by the silica particles(lower strength).
When alumina particles are passivated to a certain extent in the grinding process,it will be separated from the
silica particles and fall off,then appears a new cutting edge again,which is similar to the principe of SG abrasive.
Therefore black fused alumina has the good self-sharpness,not easy to burn the treatment surface.
Compared with other higher hardness abrasives such as brown fused alumina ,black fused alumina has the
outstanding advantage of polishing stainless steel tableware:
its moderate hardness and good self-sharpness will generate little heat in the treatment surface,then hardly to
burn the treatment,finally achieve uniform and bright color.
4. How to use black fused alumina to polish the stainless steel?
When polishing the stainless steel,the common polishing method is to put several cloth wheels on the rotating
shaft of polishing machine.
Adding the bone glue or resin bond to the outer circle of the cloth wheels,then roll the cloth wheels in the plate
fulfilled with black fused alumina,ensure the outer circle of cloth wheels is evenly glued with black fused alumina,
then dry the cloth wheels. Then load it onto the polishing machine, when polishing machine rotates,the polished
part will be contacted with the outer circle of cloth wheel under a suitable pressure to finish the polishing.
In addition,black fused alumina is also available to produce sandpaper,sandbelts or convert into flap wheels etc
to polish the stainless steel and other products.
