In China, white fused alumina manufacturers are mostly in Henan Province and Shandong Province. This week, WFA factories in those areas raised white fused aluminum oxide prices.
After the Chinese New Year, the white aluminum oxide price is a little higher than last month.
After the low price range since last November, the white fused alumina price bounced during the past week. That is because of aluminum oxide raw material raised about 15 USD per ton. In our Henan Province, the latest white fused alumina Grit price is 860-890 USD per ton.(EXW price)
White fused alumina powder (white corundum powder) is a wear-resistant material for train brake pads. It can significantly improve the performance of the brake system.
White fused alumina is also called white fused alumina. It is an artificial abrasive material made by the fusing process. WFA is a high-grade refractory raw material and a commonly used wear-resistant material. The main crystal phase of fused white corundum is α-Al2O3 (Alpha Aluminum oxide), the color is white and flawless.
Generally, white fused alumina with grits F60/F80/F120/F220 works as the sandblasting medium for gel coat mold. The higher the mesh number, the smaller the particles of white fused alumina. Accordingly, it will get a finer matte effect.
Aluminium oxide sandblasting powder is suitable for the restoration of dental ceramic dentures. Especially for bonding zirconia substrate and decorating zirconia ceramic materials.
White fused Al2O3 powder for paint always works as a filler material for paints. It can improve wear resistance, corrosion resistance performance. In the formulation of coating paint, there are necessary fillers besides the main resin material. The adding fillers can adjust coating performance such as durability, flatness, etc.
In the smelting of white fused alumina, industrial alumina powder is used as raw material. There always are some impurities in the crystallization process of white corundum during the smelting process. These impurities mainly include SiO2 (silicon dioxide), Na2O (sodium oxide), CaO (calcium oxide), Fe2O3 (iron oxide), and so on. They will directly affect the white-fused alumina quality.
During the second week of December, the aluminum oxide price drops at the pace of last week. In the past month, the price of industrial Al2O3 powder dropped about24% from 660USD to 505 USD per ton. From the end of the market, demand for white fused alumina is still weak. So there is not much support for the white fused alumina price trend.
