Brown fused alumina melt film precision casting sand is based on the production of the brown fused alumina and with special technology, it is produced by the careful organization of the researchers. The quality has reached the advanced level of similar foreign products through laboratory tests and production in practice of dozens of casting enterprises. And some performances of it can be adjusted or showcased according to the customers requirement. The precision casting sand with high refractoriness, low thermal expansion coefficient, good thermal stability, strong air permeability, high intensity, easy to shell, high casting finish.It can substitute Zirconia sand (powder) its price is only half of zirconia sand (powder), and the recovery ratio is high as well. It can be mainly applied to the melt films and silicasol technology of jewelry, handicrafts, stainless steel products, watches, glasses, aluminum die casting industries, and can be processed in line with the demands of the clients.
