Copper-Nickel-Silicon Strip Certifications
Copper-Nickel-Silicon Strip Advantages
-
Cop-ni-si alloy has good resistance to high temperature softening and thermal stress relaxation, which can improve the reliability of devices at high temperature
-
Copper-nickel-silicon alloy has good surface quality and uniform precipitation phase dispersion, which can improve the electroplating quality of products in the subsequent process.
-
Copper-nickel-silicon alloy has good bending performance, which can meet the requirements of subsequent stamping.
