High Quality Brown Fused Alumina

Detailed Product Description

1. Description:

♦ We specialized in manufacturing grit/micropowder of brown aluminum oxide. 

♦ Brown Fused Alumina is a product manufactured by gradual melting reduction of calcined bauxite in an electric arc furnace at high temperature (approximately 2000 degrees Celsius). Its chemical composition consists mainly of Al2O3 (94.5-97%) and vestigial amounts of TiO2, SiO2, Fe2O3, CaO and MgO.

♦ Brown Fused Alumina is characterized by good toughness, high mechanical resistance and hardness (9 in Mohs scale). The micro hardness of the material reaches about 1900kG/mm2.

♦ It is hard and tough material, which is the perfect material specifically manufactured to be used for general abrasive applications in bonded and coated abrasive tools, and lapping and polishing processes.

2. Applications:

♦ Wet and dry blasting

♦ Grinding, lapping and polishing media

♦ Resin bonded grinding wheels and segments

♦ Resin bonded abrasive and coated abrasive products

♦ Wear-resistant and fire-proof products 

♦ Friction products and abrasion resistance ground

♦ Producing mold of precision casting
