Copper alloy conductive block CNC machining
,High conductivity wear resistant CNC parts
,Custom precision CNC mechanical parts
- 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.
