Aluminum is a silvery-white light metal with one third the density of steel. In materials engineering, “aluminum” refers to all materials based on the element aluminum. This includes pure aluminum (at least 99.0 % Al), ultra-pure aluminum (at least 99.7 % Al) and, in particular, aluminum alloys, which have strengths comparable to steel. Aluminum alloys are divided into wrought alloys and cast alloys depending on how they are produced.

A brass coating can be obtained galvanically in a cyanide bath with copper sulfate and zinc sulfate, from which both metals are cathodically deposited together as an alloy. Adding small amounts of gold(III) chloride produces a more golden color.
