contact2019924 · Dezincification is a process which selectively removes zinc from an alloy, leaving behind a porous, copper-rich structure that has little mechanical strength. Dezincification can show itself in a variety of ways depending on the water composition and service conditions. It may present itself as dull red spots on the surface of brass.
contactAdding arsenic to naval brass can hamper zinc dealloying. High-copper brasses with 15% or less of zinc may be resistant to dealloying too. You can also consider putting in nickel silvers for greater dezincification resistance. Likewise, augmenting naval brass with phosphorous or antimony at 0.02% to 0.10% levels can make dealloying-resistant brass.
