Experience gained from laboratory tests has been incorporated into the design of the surface protection. The nickel coating provides effective protection against the loss zinc atoms from the brass. negative) with respect to steel. Zinc protects against corrosion for long time even after the zinc coating has been partially damaged scratches pores. Environmental compatibility plays crucial role the selection of materials. All materials are subjected to the rigorous quality control measures of system certified DIN EN ISO 9001. The selection, processing and surface treatment all the metals used by Weidmüller are carried out according to the latest technical standards.10 1282250000 2012/2013 . The surface protection conforms to the highest standards.Materials Metals Metals Only materials that have proved suitable for electrical engineering applications are used Weidmüller products. Conductive materials The current-carrying materials copper, brass and bronze are characterised by their high conductivity and good mechanical properties. order guarantee the long-term solderability (shelf life), brass parts are given additional nickel coating diffusion barrier. The metal ions the zinc migrate to the steel, which provides long-term protection for the parent metal. Solder connections are also given a coating tin. the presence electrolyte, zinc acts as a cathode (i.e. The surfaces are usually given a coating tin, which creates an extremely good, “malleable” contact with low contact resistance. Apart from ensuring consistently good electrical properties, the tin coating provides excellent protection against corrosion. Zinc Zinc Steel + Crack Elektrolyte W Technicalappendix W.
