MALLEABILITY

that property of a metal by virtue of which it can be hammered or rolled out in a thin sheet. It forms with ductility the more general property of plasticity, but the most malleable metals are not by any means the most ductile; lead, for instance, may be beaten into a very thin sheet, but cannot be drawn out into a fine wire. The property of M. varies with temperature, and the introduction of foreign substances, but of the ordinary metals, lead by hammering, and gold by rolling can be reduced to the thinnest sheets. province, S.
