negative) with respect to steel. The nickel coating provides effective protection against the loss zinc atoms from the brass. All materials are subjected to the rigorous quality control measures of system certified DIN EN ISO 9001.10 1282250000 2012/2013 . Apart from ensuring consistently good electrical properties, the tin coating provides excellent protection against corrosion.Materials Metals Metals Only materials that have proved suitable for electrical engineering applications are used Weidmüller products. The surfaces are usually given a coating tin, which creates an extremely good, “malleable” contact with low contact resistance. Conductive materials The current-carrying materials copper, brass and bronze are characterised by their high conductivity and good mechanical properties. The selection, processing and surface treatment all the metals used by Weidmüller are carried out according to the latest technical standards. Steels Steel parts required maintain the contact force permanently are electrogalvanised and treated with an additional passivation technique. Environmental compatibility plays crucial role the selection of materials.e. Experience gained from laboratory tests has been incorporated into the design of the surface protection. order guarantee the long-term solderability (shelf life), brass parts are given additional nickel coating diffusion barrier. Solder connections are also given a coating tin. The metal ions the zinc migrate to the steel, which provides long-term protection for the parent metal. the presence electrolyte, zinc acts as a cathode (i. Zinc Zinc Steel + Crack Elektrolyte W Technicalappendix W. Zinc protects against corrosion for long time even after the zinc coating has been partially damaged scratches pores. The surface protection conforms to the highest standards
