abrasive aluminium oxide,
High Density Precision Casting Materials Brown Aluminum Oxide Powder 320mesh-0
RS Brown fused alumina 98% is made by a special technique in electric arc furnaces with high temperature above 2300°C and refining with longer time. RS Brown fused alumina 98% is the ideal product which can substitute white fused alumina, compact fused alumina and tabular alumina in China .
RS Brown fused alumina 98% sand (Barmac production line) and powder (acid washing) produced by Rui Shi plant is characterized by without bursting, without pulverising and high bulk density, good flow property etc,
1, For variety of shaped refractory material products,
2, For corundum castable refractory,
Brown fused alumina melt film precision casting sand is the latest corundum products self- developed by RuiShi Companytomeetemeedemands. Based on the production of the brown fused alumina and with special tehology, it is produced by the careful oganizincd eresearchers. The quality has reached the advanced level of similar foreign products through laboratory tests and productioninpracticeofdozensof casting enterprises. And some performances of it can be adjusted or showcased according to the customers' requirement. Theprecisioncatiosand of RuiShi Brand has high refractorinesss, low thermal expansion cofficient, good thermal stability, strong air permebilit,higitensty,easto shell, high casting finish.It can substitute Zirconia sand (powder) its price is only half of zirconia sand (powder), and the recovery ratioishighaswell.It can be mainly applied to the melt films and silicasol technology of jewelry, handicrafts, stainless steel products, watches, glasses, aluminumdiecasting industries, and can be processed in line with the demands of the clients.
Remark: specification and size can be optimized by per customer' requirement
