Innovating Safety & Productivity for the Corrosion Control Industry
Rapijet CS - Copper Slag
RS Blastech's copper slag is manufactured from processed mineral slags which have less than 0.1% free silica, developed within the Control of Substances Hazardous to Health Regulations.
Copper slag is a very common low cost, expendable abrasive which contractors use to remove unwanted finishes or residue including rust, paint and other materials from the surface of metal or stone, which helps prepare the material's surface for painting.
A quality material and is a popular alternative blasting medium in industrial cleaning to sand. Companies can additionally use copper slag to clean large smelting furnaces or equipment utilising blasting or high-pressure spraying techniques.

In addition to its obvious qualities as an expendable abrasive for conventional dry blasting, one physical characteristic of Blastech Copperslag is that it does not absorb water, making it equally efficient when used with water. Thus the relevant grade can be used in applications such as selective removal of coatings and chemical residues from steel substrates.
The Advantages of using Blastech Copperlag:
- Economical
- No Free Silica
- Chloride content below < 25 PPM
- Sharp and angular material - excellent cutting
- High Hardness
- Better productivity
- Easily Disposed of
