Copper shot is a metal abrasive widely used in industrial surface treatment, primarily made from copper material, offering unique finishing, strengthening, and decorative effects. Below is comprehensive information about the product introduction:

Copper shot, also known as copper wire cut shot, copper wire rounded shot, pure copper shot, etc., is a granular material refined through processes like wire drawing, cutting, and rounding, appearing as golden, shiny spherical or cylindrical beads.
- Red copper shot: Copper content about 96%-99%, with very few impurities, suitable for high-purity requirement scenarios.  
- Brass shot: Copper content about 62%, zinc content about 37.5%, higher hardness (180-205Hv), suitable for strengthening treatment.  
- Special alloys: Some products may contain small amounts of tin (Sn) or phosphorus (P), for example, a certain model of copper shot contains Cu 88.05%-89.3%, Sn 10.5%-11.5%, P 0.2%-0.45%, applicable for specific sandblasting operations.
Physical Properties  
- Specific gravity: Brass shot about 8.6g/cm3, red copper shot may be slightly lower due to higher purity.  
- Hardness: Brass shot is 180-205Hv, red copper shot has lower hardness (e.g., 65-125Hv), suitable for scenarios with low surface wear requirements on workpieces.
Specifications and Forms  
- Diameter range: Conventional specifications are 0.2mm-3.0mm, some manufacturers can customize up to 4.0mm.  
- Forms: Divided into spherical (rounded shot) and cylindrical (cut shot), some products are classified into types like G1, G2, etc., based on shape grade.
Production Process  
Made from copper wire through processes like drawing, cutting, rounding, and passivation, some require grinding or passivation treatment to improve surface smoothness.
Application Fields  
- Surface treatment: Used for surface finishing, strengthening, matte, or color enhancement of workpieces such as valves, electrical accessories, and decorations.  
- Special uses: Sandblasting cleaning of molds, filter media, or for deburring, fatigue resistance, and corrosion treatment of non-ferrous metal castings.
Product Features  
- Golden and shiny appearance, enhancing the aesthetics of workpieces.  
- Moderate hardness and high specific gravity, suitable for sandblasting operations requiring high impact but low wear.  
- Environmentally friendly and efficient, suitable for precision workpiece treatment.
