Brown Corundum
Thanks to its wear resistance and excellent abrasive properties, corundum is used in processes such as:
- Removal of rust, oxides, and burrs from iron and steel structures.
- Deburring and finishing of castings
- Surface roughness, pre-painted, Teflon coating, plastic coating, rubber coatings
- Removal of scale and burrs from the surfaces of the parts to be treated.
- Removal of unwanted colored surfaces resulting from the heat treatment process.

Descripción
Corundum, both white and brown, is the most widely used industrial abrasive in blasting and surface preparation processes. It is composed of electrofused aluminum oxide (alpha alumina), which gives it high hardness (2000–2100 Knoop) and excellent cutting ability.
Types of corundum
- White corundum: higher purity and hardness, ideal for high-precision work and fine finishes.
- Brown corundum: It contains titanium and iron oxides, which give it greater toughness and versatility in general applications.
Main Advantages
- High hardness and wear resistance.
- High cleaning and grinding capacity.
- Reusable for multiple cycles
- Compatible with various projection systems
- Excellent value for the price
Applications of corundum.
Corundum is an extremely versatile abrasive used in a wide range of industrial processes:
- Stripping of rust, paint and coatings
- Deburring of metal parts
- Surface preparation for painting or electroplating
- Improved adhesion (rubber-to-metal bonding)
- Engraved on stone, marble, or granite
- Satin finishing of glass, metals and plastics
- Finishing of castings
- Correction of surface defects
Application systems
Corundum is primarily used in compressed-air blasting (shot blasting or sandblasting) and can be applied using various technologies:
- Venturi systems (suction)
- Direct-pressure systems.
It is also used in other industrial applications such as:
- Sandpaper and coated abrasives
- Grinding wheels
- Vibration chips
Compatible devices
The most common applications for corundum include:
- Manual blasting booths (suction or pressure)
- Portable sandblasters
- Blast rooms
- Dry and wet blasting machines.
- Equipment with an air gun
