CZ109 (CW509L)

CZ109 (CW509L) is a lead-free form of alpha-beta brass containing approximately 60% copper, 40% zinc and a trace of iron. It is a general purpose alloy that offers excellent hot working properties for corrosion-resistant machine parts. Also known as Muntz metal, the alloy is named after George Fredrick Muntz, who commercialised it following a patent of 1832. Notably, CZ109 (CW509L) was used on the hull of the Cutty Sark.
