  • C17510

    C17510 beryllium nickel copper (NBC), comprehensive performance is better than chromium zirconium copper, and has good creep resistance, easy to process. Used in resistance welding (butt welding), it can be processed into spot welding electrodes, electrode caps, electrode blocks, electrode arms, conductive tips, electrode tips, sealing molds, etc. The advantages are good conductivity, high hardness, less repairs, use Long life, can be widely used in automotive, aircraft, machinery manufacturing, household appliances, hardware and electronics industries.

      On the basis of maintaining high strength, fatigue resistance, and processability, it has particularly improved the conductivity (up to 60% conductivity). It has a wide range of applications in the current market of fast battery charging Background;
      C17510 copper alloy is widely used as connectors, terminals, relays, springs, switches or construction materials, daily necessities, mechanical components, etc., as components of electrical / electronic equipment;

    Note: In the Brush name:
    "A" stands for solid solution annealing (annealed, the alloy is in the softest state, and it is easy to be stamped and formed, and needs to be processed in the next cold process or directly strengthened during the expiration period);
    "H" stands for cold working state(hard);
    "T" indicates that the material has been subjected to aging hardening by standard heat treatment (heat treatment indicates that the aging strengthening heat treatment has been performed).
