Brass Cutting Beads Grinding Beads

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, or pure copper shot, 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 requirements.  
- Brass shot: Copper content about 62%, zinc content about 37.5%, with higher hardness (180-205Hv), ideal for strengthening treatments.  
- Special alloys: Some products may contain small amounts of tin (Sn) or phosphorus (P), for example, a certain type of copper shot contains Cu 88.05%-89.3%, Sn 10.5%-11.5%, P 0.2%-0.45%, suitable 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 applications requiring low surface wear on workpieces.
Specifications and Forms  
- Diameter range: Conventional specifications from 0.2mm to 3.0mm, some manufacturers can customize up to 4.0mm.  
- Forms: Divided into spherical (rounded shot) and cylindrical (cut shot), some products are classified by shape grade into types like G1, G2, etc.
Production Process  
Made from copper wire through processes like wire drawing, cutting, rounding, and passivation, some require grinding or passivation to improve surface smoothness.
Application Areas  
- Surface treatment: Used for surface finishing, strengthening, matte, or color enhancement of workpieces such as valves, electrical components, and decorations.  
- Special uses: Sandblasting to clean molds, filter media, or for deburring, fatigue resistance, and corrosion resistance 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, ideal for precision workpiece treatment.
