Listed as an engraving brass CZ120 is a classic leaded machining alloy primarily available in sheet form. The alloy is an alpha beta brass with a 2% lead addition that gives the alloy its free cutting properties.
Traditionally used for machine engraved nameplates and signs it also offers a good combination of strength, corrosion resistance and hot formability. The duplex phase structure however, does mean this alloy is not suitable for acid etched work..
