Muntz Metal

Muntz Metal is an alloy of copper and zinc which contains more zinc than the ordinary variety of brass. It is also known as yellow metal, and is very largely employed for the sheathing of ships. It is usually prepared by melting the copper in a furnace and running it out into the molten zinc, the proportions being about three of copper to a little over two of zinc. A part of the zinc is, however, always lost by volatilisation.
