Abstract
Abstract A method of fabricating a metallic hermetic sealing cover for a container comprises plating a strip of base metal with a material comprising preponderantly a precious metal such as gold to a thickness of 40% to 90% of the ultimate required minimum surface thickness, which may be 25 to 100 microinches, preferably about 40 microinches, dividing the strip into cover elements of predetermined size, and barrel-plating such cover elements with the plating material to provide a resultant minimum thickness of surface plating substantially equal to the required minimum thickness.
