White fused alumina is an important industrial abrasive, mainly made of high-purity structure (Al2O₃), with excellent physical and chemical properties. Its color is white, the pore size is high, the Mohs hardness reaches 9, the order is diamond, and the performance is excellent in a variety of applications.
Main characteristics of white fused alumina
High porosity: The porosity of white fused alumina is higher than that of brown fused alumina , but the strength is slightly lower.
High temperature resistance: It can withstand high temperature environment and is suitable for refractory materials.
Chemical stability: It has good resistance to acid and alkali corrosion.
Self-sharpening: It maintains a sharp cutting edge during grinding.
Low heat generation: The heat generated during grinding is extremely small, which is conducive to protecting the workpiece material.
Main uses of white fused alumina
Grinding and abrasive tool manufacturing:
Used to cut materials such as high-carbon steel, high-speed steel and stainless steel, and manufacture various tools such as grinding wheels and polishing abrasive tools.
Polishing: Fine white fused alumina is often used for surface polishing of hardware products and handicrafts, which can provide a white and undamaged surface effect. Sandblasting and rust removal: Used to remove the oxide layer and gradient on the metal surface, suitable for the surface treatment of gravity die-casting molds, rubber molds, etc.
Refractory materials: Widely evaluated for the furnace walls and roofs of high-temperature furnaces, and for the manufacture of refractory bricks and other insulating materials.
Mechanical manufacturing: In the field of mechanical processing, it is used to improve the surface quality and precision of parts. Chemical fillers: As catalyst carriers or adsorbents, improve chemical reaction efficiency and product quality.
Other applications: Including jade carving, mold making, and ultra-fine grinding in the electronics industry.
Summary:
White fused alumina inherits inherited properties and is widely evaluated in multiple industries, including mechanical manufacturing, chemical industry, construction and art. Its high stability and stability make it an ideal raw material choice for grinding.
