Release Date:2023-08-21 10:13

Abrasives are indispensable tools in the realm of material processing, finding their application in an array of industries. From the robust Brown Fused Alumina to the versatile White Fused Alumina, the distinctive properties of different abrasives cater to the diverse needs of industries ranging from precision machining to refractory materials.

Brown Fused Alumina - A Stalwart in Grinding

Brown Fused Alumina, derived from bauxite and subjected to high-temperature fusion, boasts a characteristic brown hue, high hardness, and remarkable toughness. These qualities make it an ideal choice for crafting abrasives for grinding carbon steel, malleable cast iron, and hard bronze. Its applications span from grinding to refractory materials, chemical fillers, precision casting, and even anti-skid materials.

White Fused Alumina - The Essence of Precision

White Fused Alumina, forged from aluminum oxide powder through high-temperature fusion, dazzles with its pure white appearance, marginally higher hardness than Brown Fused Alumina, and slightly reduced toughness. In the realm of abrasives, it takes center stage in manufacturing tools catering to high-carbon steel, high-speed steel, and quenched steel grinding. Additionally, it is instrumental in tasks like grinding, polishing brushes, crafting precision casting sands, spraying materials, and serving as a catalyst carrier in chemical processes.

Pink Fused Alumina - The Touch of Elegance

Pink Fused Alumina, also born from aluminum oxide powder via high-temperature fusion, exudes a graceful pink hue. Its hardness rivals White Fused Alumina's, while its heightened toughness sets it apart. Pink Fused Alumina holds its ground in producing durable tools, offering high precision and an immaculate finish. Its applications flourish in realms like precision grinding for gauge blocks, spindle parts of machine tools, instrument components, thread workpieces, and template grinding.


Monocrystalline Fused Alumina - Precision Redefined

Monocrystalline Fused Alumina, nurtured from bauxite with a dash of sulfur, stands as an epitome of precision machining. Its shade oscillates between gray-white and pale yellow, embodying high hardness, robust toughness, and predominantly single-crystal particles. This abrasive take on the challenge of grinding stainless steel, high vanadium high-speed steel, and deformable and heat-sensitive workpieces with unmatched prowess.

Black Silicon Carbide - The Cutting Edge

Black Silicon Carbide, characterized by its brittleness, sharpness, conductivity, and heat conductivity, boasts a micro-hardness range of 3100 to 3280 kg/mm². It emerges as an ideal choice for processing metals and non-metals with low tensile strength, including gray cast iron, brass, aluminum, stone, leather, and rubber. Its utility extends to refractory materials and the electronics industry.

Green Silicon Carbide - Precision Meets Fragility

Green Silicon Carbide, marked by its high purity and brittleness, shines with a micro-hardness ranging from 3280 to 3400 kg/mm². It finds its niche in processing hard and brittle materials like hard alloys, optical glass, marble, ceramics, and other similar non-metallic materials. Additionally, it serves as a building block for advanced refractory materials, electric heating components, and electrical devices.

A Tapestry of Applications

In a symphony of abrasive diversity, each variant finds its place in various industries, from mechanical precision to refractory innovation. These abrasives, with their distinct properties and applications, underpin the very fabric of sectors, enhancing efficiency, accuracy, and quality across the board.
