is a copper alloy typically composed primarily of copper
(Cu) and zinc (Zn). Brass is softer than bronze
and has a muted yellow color, somewhat similar to gold. It is relatively
resistant to tarnishing, and is
often used as decoration and for coins.
Applications where low friction is required such as
locks, gears, bearings, ammunition, and valves; for plumbing and electrical
applications.
Also see bronze.
