Overview


CuMn30Ni5 Manganese Copper Alloy Bar is engineered for extreme high-temperature and high-resistivity applications, combining resistivity (0.42-0.48 μΩ·m) and tensile strength (600-800 MPa) through optimized Mn-Ni-Cu composition (28-32% Mn, 4-6% Ni). With outstanding oxidation resistance and creep stability, it operates reliably from -60°C to 450°C, ideal for power electronics, aerospace heaters, and nuclear systems. Compliant with ASTM B267 and IEC 60168, offering full traceability certification.
