White aluminum oxide blast media F12#-F240# clean and dust-free
1. Product Introduction of the white aluminum oxide blast media
White aluminum oxide blast media is white, with good purity and good quality. The white aluminum oxide is free of impurities, so the white corundum abrasive will not affect the color of the workpiece when processing the workpiece. It is suitable for polishing, grinding, and wet sandblasting. The workpiece does not need to be cleaned after treatment, which reduces the production steps and saves the cost. The sandblasting white aluminum oxide has high production efficiency. The smaller the particles of white aluminum oxide, the greater the impact force can be generated through the impact contact between much white aluminum oxide and the object surface to be polished. The higher the utilization rate of abrasive, the better the relative treatment effect.

8. FAQ:
WHAT IS THE DIFFERENCE BETWEEN ALUMINIUM OXIDE AND WHITE FUSED ALUMINA?
Al2O3 alumina is the starting material of aluminium production, both of metallic aluminium and aluminium oxide. It is porous an has a large reactive surface.
WHAT IS THE SPECIFIC WEIGHT?
The specific weight is the ratio of the weight of a body to its volume. The specific weight of corundum under normal conditions is 3.94 g/cm3.
WHAT IS FEPA AND WHAT DOES IT DO?
FEPA is the Federation of European Producers of Abrasives. Its mission is to develop and publish standards, documents and comprehensive safety instructions for the abrasive industry.
Abrasive grain sizes are produced and sold according to the FEPA standard, among other things. This is to ensure that a consistent quality for any abrasive can be achieved across different manufacturers.
