Alumina hitam menyatu (BFA) Applications – Showcase

This showcase presents Black Fused Alumina Applications in grinding, polishing, blasting, and refractories. BFA stands out for its toughness, conductivity, and cutting efficiency. Lebih-lebih lagi, it supports both precision finishing and impact-intensive work.

Keterangan

Manufacturers melt high-quality bauxite with a reducing agent in an electric arc furnace to create Black Fused Alumina. The process produces a black, angular abrasive rich in Al₂O₃ with small amounts of iron oxide and titanium oxide. Karena itu, BFA combines toughness, moderate hardness, and strong cutting ability. Sebagai akibat, industries use it widely for demanding surface preparation.

Key Benefits of Black Fused Alumina Applications

• Sharp grains cut hard alloys such as carbon steel and stainless steel.

• High toughness reduces breakage and extends service life.

• Strong thermal conductivity supports stability in high-heat operations.

• Cost-effective compared with alternative abrasives. Selain itu, it ensures consistent performance.

Industrial Applications

Black Fused Alumina is used in bonded abrasives like grinding wheels and cutting discs. Lebih-lebih lagi, coated abrasives such as sandpaper and abrasive cloth rely on BFA. Foundries and machine shops use it for blasting and polishing cast iron and alloy components. Akibatnya, coatings adhere better and last longer.

Advanced Uses

Refractory makers apply BFA in firebricks, castables, and kiln linings. Likewise, industries add it to anti-skid flooring and high-friction surfaces. Overall, Black Fused Alumina delivers balanced performance, combining durability and cutting power across multiple sectors.
