High Tensile Solid Copper Round Bar 150MPa -400 MPa Strength For Automotive Bushings
High Tensile Copper Round Rod 150-400 MPa Strength For Automotive Bushings
High-Tensile Copper Round Rods are engineered for automotive applications demanding exceptional strength, wear resistance, and longevity. With tensile strengths ranging from 150–400 MPa, these rods are ideal for bushings, bearings, and suspension components in vehicles. Manufactured from C18150 chromium copper alloy (CuCr1Zr) and compliant with IATF 16949 automotive standards, they combine high mechanical performance with corrosion resistance for harsh operating environments.
Key Advantages:
- High Strength-to-Weight Ratio: Tensile strength up to 400 MPa for heavy-load automotive parts.
- Superior Wear Resistance: Chromium-enhanced surface hardness (70–200 HV) reduces bushing wear.
- Thermal Stability: Maintains performance at -50°C to 250°C (tested per SAE J2599).
- Corrosion Resistance: Resists road salt, oils, and moisture (ASTM B117 salt spray tested).
- Precision Machinability: Tight tolerances (±0.05mm) for CNC and lathe processing.
- Global Compliance: RoHS, REACH, and IATF 16949 certified for automotive OEMs.
- Custom Solutions: Cut-to-length (100mm–6m), polished, or nickel-plated finishes.
