WebWhen laying communications from copper pipes, they can be docked with pipe products made of plastic, steel and brass.With regard to the connection with galvanized products, experts recommend avoiding such combinations, since there is a high probability of chemical processes between two elements - copper and zinc. WebThis plating is a combination of a high-nickel zinc-nickel alloy (10–15% nickel) and some variation of chromate. The most common mixed chromates include hexavalent iridescent, trivalent or black trivalent chromate. Used to protect steel, cast iron, brass, copper, and other materials, this acidic plating is an environmentally safe option. [6]
