Brass is any alloy of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses, each of which has unique properties[1]. Note that in comparison bronze is principally an alloy of copper and tin.[2]. Despite this distinction, some types of brasses are called bronzes. Brass is a substitutionary alloy. It is mainly used for decorative, plumbing and electrical applications.
Found during Bronze Age.

Brass is an alloy of the metals copper and zinc (not aluminium).)in various proportions according to what it is to be used for. As to who invented brass we simply do not know, it has been around for thousands of years (mentioned in the O.T. Bible) The most probable truth is that it was found by accident some time after the Bronze Age. The ores of zinc are often found associated with the ores of tin (bronze being the alloy of copper and tin) and could well have been confused by our ancestors resulting in zinc replacing some or all the tin in their attempts to produce bronze. We will never really know as there were no written records kept so long ago.
