Providing a copper alloy plate, in which center Mg concentration at a center part in a plate thickness direction 0.1 mass % or more and less than 0.3 mass %, center P concentration is 0.001 mass % or more and 0.2 mass % or less, and the balance is composed of Cu and inevitable impurities; in which surface Mg concentration at a surface is 70% or less of the center Mg concentration; in which a surface layer part defined by a prescribed thickness from the surface has a concentration gradient of Mg of 0.05 mass %/m or more and 5 mass %/m or less increasing from surface toward center part of the plate thickness direction; and in which restraint of color change of the surface and increase of electrical contact resistance, and adhesiveness of a plating film are excellent due to maximum Mg concentration in the surface layer part is 90% of the center Mg concentration.

A method of fabricating and using a zinc negative electrode and systems thereof are described. A zinc electroplated electrode including a layer of zinc metal bonded to a surface of an electrically conductive current collector is fabricated by an electroplating process using a zinc electroplating system. The zinc electroplating system includes: a zinc metal anode, a cathode including the current collector for plating zinc thereon, and an electrolyte bath comprising zinc ions. The electroplating process bonds the zinc metal to the surface of the current collector to create the electroplated zinc electrode. The electroplated zinc electrode is used as a negative electrode in a zinc metal cell. The zinc metal cell may be a primary cell or a secondary cell.
