Wrought Materials - Copper-Zinc-Lead Alloys - Leaded Brasses

Common names: Architectural "Bronze"

A copper-zinc-lead alloy with a duplex alpha-plus-beta phase structure containing a dispersion of fine lead particles. A small amount of aluminium is sometimes added to improve the tarnish resistance of the alloy, which is generally supplied only as extruded rod and sections. The material has excellent hot-working properties and good machinability, and is typically used for decorative and architectural applications.
