Abrasivos de Escória de Cobre
DiamondCore Copper Slag
Abrasivos de escória de cobre (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. Como resultado, copper slag abrasives effectively remove rust, escala de moinho, and old coatings from steel surfaces before coating, pintura, or corrosion protection.
During blasting, operators propel abrasive particles toward the work surface to clean and prepare metal structures for protective coatings. Além disso, DiamondCore copper slag abrasives are used in shipyards, plantas de fabricação de aço, manutenção de tanques, e projetos de infraestrutura. Além disso, consistent grading and reliable blasting performance support efficient surface preparation for contractors and abrasive distributors worldwide.
Our Grit characteristics
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.
High Blasting Efficiency
Angular particles provide strong cutting power for removing rust, escala de moinho, and old coatings.
Consistent Grading
Controlled particle size distribution ensures stable blasting performance and predictable surface profiles.
Low Free Silica
Low free silica content helps reduce health risks during abrasive blasting operations.
Reliable Industrial Supply
Stable production capacity supports large projects and international export supply.
