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

Common names: Clock Brass
  Engraving Brass
  High-Leaded Brass - Riveting Brass

A copper-zinc-lead alloy with a duplex alpha-plus-beta phase structure containing a dispersion of fine lead particles. The alloy, which is fairly readily cold formed and easily machined, is typically used in the production of headed components an for clock manufacture.
