36 Plating & SURFACE FINISHINGA pplicationsElectroplated Copper from Cyanide -based Plating solutionshas long been used both as an engineering or decorativefinish, and as an undercoat for other plated metals. Thesecyanide Copper solutions are used to plate on a wide varietyof base materials. These include steels, zinc alloys, aluminumalloys, Copper alloys, magnesium alloys, nickel alloys, andlead alloys. An important property of Copper from Cyanide -based systems is its ability to adhere well to these properties of electroplated Copper deposits that are ofinterest for various applications include: (a) soft, ductiledeposits; (b) it is easily buffed; (c) good electrical conductiv-ity; (d) good solderability; (e) stop-off properties on steel forselective case-hardening processes ; (f) decorative finishescan be
selective case-hardening processes; (f) decorative finishes can be plated bright with proprietary additives, or given attractive antique finishes such as oxides or patinas, (g) copper plate from cyanide plating solutions protects acid-sensitive base metals from attack by subsequent acid plating solutions; and (h) it plates easily with other metals.
