Bahan pelelas sanga tembaga (iron silicate blasting media) are produced from granulated slag generated during metal smelting processes. The material forms hard, angular particles that provide strong cutting performance for abrasive blasting and industrial surface preparation. Akibatnya, copper slag abrasives effectively remove rust, skala kilang, and old coatings from steel surfaces before coating, melukis, or corrosion protection.
During blasting, operators propel abrasive particles toward the work surface to clean and prepare metal structures for protective coatings. Selain itu, DiamondCore copper slag abrasives are used in shipyards, loji fabrikasi keluli, penyelenggaraan tangki, dan projek infrastruktur. Lebih-lebih lagi, consistent grading and reliable blasting performance support efficient surface preparation for contractors and abrasive distributors worldwide.
7 grade hardness according to Moh’s scale.
Irregular prismatic shape with a lot of sharp edges, which gives great abrasiveness and kinetic energy produced by weight and speed in airstream.
Suitable for all kinds of blasting with standard equipment for that purpose.

Angular particles provide strong cutting power for removing rust, skala kilang, and old coatings.

Controlled particle size distribution ensures stable blasting performance and predictable surface profiles.

Low free silica content helps reduce health risks during abrasive blasting operations.

Stable production capacity supports large projects and international export supply.
