Model Number: Brown Fused Alumina-#0283
Brand Name: Brown fused alumina
Key Specifications/Special Features:
1. Description: Brown aluminium oxide/brown fused alumina is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness, good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel, general-purpose alloy steel, annealed malleable iron and hard bronze, etc. It also can be used as refractory materials.2. Application:Suitable for grinding high-speed, high carbon steelHigh-grade refractory materialsAbrasives toolGrinding and polishingCeramicsLEDSandblastingAviation3. Specification:
