Brown corundum is a tough, durable, highly versatile abrasive material that can help you tackle the toughest industrial grinding and polishing applications. Made from high-quality bauxite, BFA is melted and cooled under carefully controlled conditions to produce exceptionally hard and wear-resistant products. Its unique combination of hardness, toughness, and clarity make the BFA ideal for a variety of applications, from surface treatment to metalworking, woodworking, and more.
Brown corundum is classified according to its chemical composition and crystal structure. It is divided into two types - regular iron and low iron. Ordinary brown corundum contains 1-3% iron, while low-iron brown corundum contains less than 0.2% iron.
At Henan Advanced Abrades, we offer the highest quality brown corundum to meet your industrial needs. With its superior hardness, toughness, and density, BFA is the perfect abrasive for a variety of applications. Trust us to provide the best abrasive solution for your business.
advantages and disadvantages
1.High hardness
Brown corundum has a Mohs hardness of 9, making it one of the hardest abrades on the market. This feature ensures that it can withstand the most demanding applications and deliver consistent results over time.
2.High toughness
Brown corundum has excellent toughness, which makes it resistant to breakage and breakage. This toughness also makes it suitable for high-pressure applications where strong abrasives are required.
3.High density
The high density of brown corundum ensures that it can cut tough materials quickly and efficiently. This density also helps reduce the amount of dust produced during the cutting process, making it a cleaner and safer abrasive.
