Lead is now a very expensive metal. At one time it was used extensively for roofing and for water piping because of its softness and resistance to corrosion. But later copper and iron have taken its place. Lead is a gray malleable metal which melts at 327 ̊C, which is low for a metal. Lead is still used for roofing and for making waste pipes and sink traps because it is easily bent into shape; storage battery (accumulator) plates; storage tanks for sulphuric acid; lead shot; solder; screens to stop harmful radiation from radioactive substances. Lead monoxide is used for making glass that is brilliant and sparkling, i.e. decorative tableware.

Not all metals are strong. Copper and aluminium, for example, are both fairly weak.  But the alloy of these metals, which is called aluminium bronze, is much stronger than pure copper or pure aluminium.
