The Power of GMA Garnet as a Blasting Abrasive
Also known as the Almadine garnet, is a versatile and durable type of garnet that is gaining popularity in the blasting industry. This garnet is known for its bright pink colour, high hardness, and ability to effectively remove surface contaminants.
Characteristics of GMA Garnet for Blasting
An ideal choice for blasting abrasives due to its unique characteristics. Some of the key advantages of using it for blasting include:
- Hardness: GMA Garnet™ is harder than most other abrasives, producing a deeper, more consistent profile when blasted at the same pressure.
- Durability: GMA Garnet™ is tougher than most other abrasives, reducing the tendency to fracture on impact, resulting in deeper profiles and higher efficiency blasting.
- Low Dust Generation: GMA Garnet™ is sub-angular in shape, with enough edges to create deep profiles while minimising embedment.
- Low Profile: GMA’s heavier, denser abrasive grains outperform less dense abrasives, delivering more energy to the surface and creating deeper, consistent anchor profiles when blasted at the same pressure.
Sand Blasting Warning: Crystalline silica is a known Group 1 Carcinogen. Using Silica Sand as an abrasive blasting media has been identified by Worksafe Australia as causing Silicosis (lung condition), leading to severe illness and death. For more information please refer Silica Sand Warning
