Black Fused Alumina

Black Fused Alumina is a specialized type of fused alumina with a distinct black color. It is made by high-temperature smelting of selected bauxite ores and coal as reducing agents. This material exhibits high hardness, excellent thermal stability, and good electrical conductivity. It is commonly used in applications such as surface preparation, sandblasting, and polishing for its abrasive properties. Black Fused Alumina is known for its low iron content, making it suitable for applications where iron contamination must be avoided, such as the manufacturing of high-quality refractories and abrasive products.

Features of Black Fused Alumina

01.
Wear-resistant Castings
The steel-based wear-resistant parts made of black fused alumina section sand not only have the characteristics of high strength of steel castings, but also have the characteristics of erosion resistance and long service life, and have very broad application prospects.
02.
Wear-resistant And Non-slip Pavement Floor
Use black fused alumina section sand to lay wear-resistant and non-slip pavement, bridge deck, floor, and make wear-resistant and anti-slip floor, which can not only meet the actual needs but also have very high-cost performance.
03.
Unshaped Refractory Castable
The use of black fused alumina segment sand can make wear-resistant castables, which can be used as wear-resistant protection for various kilns and other places.
04.
Resin Cutting Sheet
Resin cutting sheet: adding an appropriate amount of black fused alumina into the brown fused alumina to make a resin cutting sheet, which can improve the durability of the resin cutting sheet, and make the cutting quality higher and the cost lower.
The ideal abrasive material supplier is always at your service.
