COLORLESS ZINCAMING Zn-AL-Cu

Description

White galvanizing is used for ZAM galvanizing most often to improve appearance and corrosion resistance. Shiny colorless zinc is similar in appearance to chromium or nickel, and this determines its scope of application as a conditionally decorative coating. However, you need to consider the possibility of zinc changing color and tarnishing over time, unlike chrome. In terms of protective ability, white galvanization is inferior to rainbow and olive. Depending on the required degree of protection of the metal surface (which is directly related to the class of environmental aggressiveness and the expected service life of the product), the thickness of zinc can range from 6 microns to 50 microns. The optimal coating thickness should be from 6 to 24 microns. The thickness of the white chromite film is no more than 0.025-0.08 microns; it does not contain hexavalent chromium. The durability of white zinc without additional treatment with polymer compounds in 5% salt spray is 20-80 hours. The use of a new solution for chromite plating allows increasing the resistance in the salt chamber to 240 hours. You can order TsAM galvanizing with colorless chromium plating in accordance with GOST 9.305-84 by phone and email indicated in the section "CONTACTS".
