Conductive materials The current-carrying materials copper, brass and bronze are characterised by their high conductivity and good mechanical properties. Environmental compatibility plays crucial role the selection of materials. Zinc protects against corrosion for long time even after the zinc coating has been partially damaged scratches pores. The nickel coating provides effective protection against the loss zinc atoms from the brass. The metal ions the zinc migrate to the steel, which provides long-term protection for the parent metal. The surfaces are usually given a coating tin, which creates an extremely good, “malleable” contact with low contact resistance. Solder connections are also given a coating tin. Experience gained from laboratory tests has been incorporated into the design of the surface protection.e.Materials Metals Metals Only materials that have proved suitable for electrical engineering applications are used Weidmüller products.
