Product Description:

Brown Fused Alumina (BFA) is created through the fusion process of bauxite in an electric arc furnace operating at extremely high temperatures. The resulting product possesses a distinctive brown color and exhibits exceptional hardness and toughness. BFA is manufactured in a tilting electric arc furnace, ensuring a high temperature resistance and robust erosion resistance. Its superior machinery strength and thermal stability make it an ideal raw material for the production of shaped refractories.

The unique properties of brown fused alumina include high purity, excellent crystallization, excellent fluidity, low coefficient of linear expansion, and resistance to corrosion. Numerous fire-proof manufacturing companies have confirmed its performance, demonstrating no explosion, chalking, or cracking during application. Notably, BFA surpasses the traditional brown corundum in terms of cost-effectiveness, making it the top choice for fused alumina refractories as both an aggregate and filler.

Features:

Brown corundum has many remarkable characteristics that make it highly sought after in various industries. Its exceptional qualities are listed below:

Brown corundum boasts a MOH hardness of 9.0, just second to diamond. This makes it an incredibly tough and durable material, with exceptional resistance to wear and tear.

One of the most impressive features of brown corundum is its high chemical stability and corrosion resistance. This allows it to withstand harsh environments, including acids, alkalis, and extreme temperatures.

Brown corundum has a very small coefficient of thermal expansion, meaning it doesn't expand or contract significantly under extreme temperature changes. This makes it resistant to thermal stress and ensures its stability in various conditions.
