‌‌Zinc-white copper wire‌ is an alloy material composed of copper, nickel and zinc, with a beautiful silver-white appearance and excellent physical properties.

Physical properties
Zinc-white copper wire has good electrical conductivity and corrosion resistance. Its electrical conductivity is slightly lower than that of pure copper, but it is still an excellent conductive material. It can resist environmental erosion such as oxidation and salt water corrosion, so it can maintain stable electrical properties in humid and corrosive environments. In addition, zinc-white copper wire can withstand pressure processing well in both hot and cold states, and has good plasticity and elasticity, but poor cutting and welding properties.

Zinc-white copper wire is widely used in many fields due to its excellent physical properties:
‌Electrical equipment‌: used to manufacture cables, wires and electronic components, especially in occasions with high electrical performance requirements.
‌Precision instruments‌: Due to its good processing performance and corrosion resistance, it is often used to manufacture precision instrument parts and precision parts of instruments and meters.
‌Communication equipment‌: In the field of communications, zinc-white copper wire is also used to manufacture high-frequency telecommunications cables and electromagnetic shielding shells.
