White corundum micropowder (mainly composed of α-Al₂O₃) has significant advantages in the field of stone polishing due to its unique physical and chemical properties, as follows: 1. High hardness and wear resistance – Mohs hardness reaches 9: second only to diamond, it can efficiently polish medium and high hardness stones such as marble and granite,

White fused alumina is very pure and extremely hard. Aluminum oxide is used to anchor pattern creation prior to coating or bonding, rust, scale removal, sweeping, matte surface finish of steel, stainless steel, aluminum, non-ferrous metals, glass, stone and other surfaces. It can be recycled and will not leave residues on the surface of the workpiece

Platelet Alumina is a high quality alumina type abrasive powder, consisting of a plate-shaped crystal of Al2O3 with a purity of over 99.0%. It has excellent heat resistant properties as well as being chemically inert, and is not corroded by either acids or alkalines. As the particle size distribution of Platelet Alumina is tightly controlled,

PWA is a white calcined alumina abrasive powder consisting of plate-shaped crystals of aluminum oxide (Al2O3) with a purity of over 99.0%.

White fused alumina lapping powder is an excellent polishing powder for stainless steel, aluminum alloy, copper, glass, and other materials.

Plate Calcined Alumina, also known as PWA or WCA, is an alumina powder with a flaky structure
