Abstract
This method of copper plating aluminum and aluminum alloy wire or strip applies an adherent and ductile plating while the wire is moving rapidly and continuously through the plating apparatus. An improved chemical zincating step followed by a copper pyrophosphate strike plating, within critical thickness limits, reduces the plating time and makes practical plating of the wire while moving at speeds of about 100 feet per minute or more in relation to the processing solution.
