Brown Fused Alumina

Brown Fused Alumina for Sand Blasting

Introduction

Kingland carefully selects first grade of brown fused alumina crude from our furnace factory, and does crushing,grading in strict accordance with the requirements. The made grains have the advantages of less crystal aggregate,large crystal size, less glassiness,good toughness and high wear resistance,are suitable for sand blasting.

Application

The grains of brown fused alumina are blocky,high bulk density,good chemical stability, high hardness, high toughness, low magnetic properties, high cleanliness, particle shape closely sized,suitable for blasting of glass, marble,granite, ceramic and so on. lt can also used for the preparation of deburring,scale removal, and the generation of matte finishes. It is widely used in the industrial applications of ship repair, industrial painting, blast room, etc

White Fused Alumina

White Fused Alumina

Introduction

White fused alumina produced by using the alumina powder as raw material, in the electric arc furnace by more than 2000 degrees high temperature melting. White Fused Alumina has the compact texture,uniform crystal, high purity and high hardness. So it is suitable for high carbon steel, high speed steel quenched steel grinding.

Application

White fused alumina is angular, moderate bulk density. The bonded abrasives made by it have good sharpness, durability and high grinding efficiency. lt is used for the production of resin abrasives and vitrified abrasives,and the processing of high carbon steel, alloy steel,quenched steel and other materials with high hardness and high expansion strength.
