Effects of Heat Treatment Process and Cold Shaping on Microstructure and Properties of CuNiSiCr Copper Alloy

    Graphical Abstract
    • Abstract
  • The effects of different heat treatment and cold deformation on microstructure and properties of lead frame alloy CuNiSiCr were studied. The results showed that the new CuNiSiCr alloy solid solution treated at 930℃ for 1 hour, and then 30% of cold deformed, followed by aging treatment at 500℃ for 3. 5 hours. The hardness and conductivity of CuNiSiCr alloy can achieve better cooperation.
