Wrought Materials - Copper-Zinc-Lead Alloys - Leaded Brasses
Common names: Free-Machining Brass
Architctural "Bronze"
A copper-zinc-lead alloy with a duplex alpha-plus-beta phase structure containing a dispersion of fine lead particles. This alloy is the standard European-type free-cutting brass, generally supplied as rod. It is widely used where extensive machining is required, especially on automatic machines. The alloy is used for architectural purposes in North America.
