Qingyun White Fused Alumina

Qingyun White fused alumina is a high-grade refractory materials, its main crystalline phase isa-Al2O3, color white, with characteristics of large volume density, low porosity, volume stability and good thermal shock resistance and other . fused alumina is for large steel castings in daily use, especially type alloy castings, sand core surface coatings and investment casting system shell material, the same time as hardened steel, alloy steel and other semi-fine grinding, abrasive grinding , fused alumina sand, Qingyun White fused alumina powder is the best material layer material in place of zircon sand .The castings made of Qingyun White fused alumina have a good gloss. The Qingyun white fused alumina made by Qingyun Refractories Co., Ltd. Is harder and brittler than brown fused alumina. Also the cutting force is stronger. Good chemical stability, excellent insulation properties. Scope: to do solid structure and coated abrasive tools, wet or dry spray sand for crystal, ultra-fine grinding and polishing of the electronics industry and production of advanced refractories. Suitable for machining hardened steel, alloy steel, high-speed steel, high carbon steel and other hard hardness, tensile strength greater material. fused alumina abrasives can also be used as catalyst, insulation and precision casting sand. Classification of according to mesh size Common Specifications: sand particle size: 16,20,24,30,36,46,60,80,100,120,150,180,200,220 (mesh) White fused alumina period of sand, micro powder, powder, grain sand . Performance and advantages of Qingyun White fused alumina grain sand 1, does not affect the color of the workpiece; 2, can be used to blast in non-iron remaining manufacturing process; 3, Powder grade is suitable for wet blasting and polished work; 4, processing speed, high quality; 5, the amount of iron oxide contained in low iron suitable for sandblasting residues of prohibited jobs.
