C17500 copper rod is a beryllium-cobalt-copper alloy material with high strength, high conductivity (conductivity ≥50% IACS), high wear resistance, good thermal conductivity (thermal conductivity 235 W/m·k) and excellent corrosion resistance. Its chemical composition is based on copper, containing 0.45%~0.75% beryllium (Be), cobalt (Co) and nickel (Ni) ≥3% in total, and the hardness can reach HB230. This material is widely used in injection mold inserts, electrodes, hot runner nozzles, high thermal conductivity bearings and other fields, especially in industrial scenarios that require rapid heat dissipation and anti-adhesion.
