Key Features
Hardness
High hardness, though slightly less than white corundum.
Toughness
High toughness, meaning it resists fracture and chipping well.
Self-Sharpening
The abrasive grains fracture in a way that exposes new sharp edges, making it effective for longer.
Durability
Resistant to wear, acids, and alkalis.
Types of Brown Corundums Available
01
Tilting Furnace Brown Corundum
This type is produced in tilting furnaces, which allows impurities to settle at the bottom, resulting in a higher purity primary block.
02
Fixed Furnace Brown Corundum
Produced in fixed furnaces, this type may have a higher concentration of impurities, affecting its overall quality and performance compared to the tilting furnace variety.
03
Grades based on Alumina Content
Brown corundum is often categorized into grades (A, B, C) based on the aluminum oxide (Al2O3) content, with higher purity grades (A) typically containing 99-99.8% Al2O3.
Applications
Environmental blasting for aluminium profile/Copper material of glass/water to wash jeans
Grinding for kinescope/glass/monocrystalline silicon/lens/jadeware
Abrasion-proof material for expressway/airstrip/dock/parking lot/stadium
