Aluminum oxide
Brown aluminum oxide is electrically fused in an arc furnace from a mixture of bauxite at high temperature. It has brown colour, high hardness and great toughness. The abrasives tools made of brown aluminum oxide are suitable for steel, malleable cast iron and hard bronze. It used for refractory aluminum oxide lining mixture, pouring materials castable, etc.
White aluminum oxide has white color and a little higher hardness and toughness comparing with the brown one. The grinding tools made of this material are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel, abrasive powder of finer grit size can also be used for precision casting and high-grade refractory.

Granulated aluminum oxide white for grinding&polishing Granulated aluminum oxide white was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling.It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
Approximately 50% lighter than metallic media, white aluminum oxide has twice as many particles per pound. The fast-cutting action minimizes damage to thin materials by eliminating surface stresses caused by heavier, slower-cutting media blasting grits. White aluminum oxide blasting media has a wide variety of applications, including cleaning engine heads, valves, pistons and turbine blades in the aircraft and automotive industries. White aluminum oxide is also an excellent choice for preparing a hard surface for painting. White aluminum oxide contains less than 0.2% free silica and is therefore safer to use than sand. The grit size is consistent and cuts much faster than other sand blasting media, leaving a smoother surface. 25kg small bag, 40 bags in one big bag.
White fused alumina for abrasive and refractory belongs to the group of electro-corundum. It is produced by controlled melting of alumina in an electric arc furnace. White fused alumina is iron-free, ultra pure and extremely hard. White fused alumina is produced by fusing calcined alumina in an electric arc furnace under carefully controlled conditions. The material produced is white in color, dense and has predominantly large crystals of alpha alumina. Ingots are crushed, ground, and precision screened in our new sizing plant to obtain very consistent sized fractions. Magnetic iron from crushing is removed by rare earth magnets to ensure very low levels of iron in the finished products. Close sized fractions are available or precision blended to specification. This process ensures a very consistent sizing from coarse to fines which is critical in many applications. White aluminum oxide has white color and a little higher hardness and toughness comparing with the brown one. The grinding tools made of this material are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel, abrasive powder of finer grit size, can also be used for precision casting and high-grade refractory.
With high toughness, black aluminum oxide is extremely suitable for polishing stainless steel and non-ferrous metals. It `s grinding efficiency is much higher than that of brown a/o and the finishing effect is much better than many of other abrasive materials. Special requirement on chemical composition can be satisfied through discussion.
