Detailed Specifications & Features
Copper Alloy Conductive Block Custom Manufacturing
Copper alloy conductive blocks are critical components for current transmission, sliding contact, and wear-resistant applications in electrical and industrial equipment. We use high-performance copper alloys such as chromium copper (e.g., C70600) and beryllium copper, processed via precision CNC machining, to ensure high conductivity, wear resistance, and longevity. These blocks are widely applied in rail transit pantographs, industrial motors, and welding equipment, capable of withstanding high-current loads and mechanical abrasion. As a specialized precision machining supplier, we offer end-to-end services from material selection to finished product processing, meeting strict requirements for accuracy and reliability.
Key Features
- High Conductivity: Conductivity up to 18-90% IACS (e.g., CuMg0.4 alloy), enabling efficient current transfer.
- Excellent Wear Resistance: Hardness of 36-42 HRC with iron powder additives or chromium copper, extending service life beyond 20,000 km.
- Arc Erosion Resistance: Rare-earth high-entropy alloy additions enhance arc resistance, reducing molten pool splatter for high-frequency switching.
- Self-Lubricating Properties: Fine graphite powder integration lowers friction coefficients, ideal for high-speed sliding contacts.
- High Strength and Heat Tolerance: Tensile strength ≥250-1000 MPa, with 95% conductivity retention at 150℃.
- Precision Machining Compatibility: CNC customization achieves tolerances of ±0.005 mm and surface roughness of Ra 0.05 μm.
