contact202097 · Dezincification is the corrosion of an alloy (i.e. metal) where the Zn in the alloy reacts preferentially in a corrosive environment. Basically it is a process in which zinc is lost and copper is left behind. Red brass (i.e. <15 wt% Zn) rarely suffers this type of corrosion because the Zn is still in the Cu matrix.
contact2020122 · The problem of severe dezincification in potable water fittings was solved in Europe in 1980 with the introduction of a brass (CZ132/CW602N) using a high temperature anneal and addition of an alloying element corrosion inhibitor to leaded brass containing 36 percent zinc [2]; In the U.S., alloys C36000 and C37700 with about 36
contactDezincification Brass (DZR) Cu-Zn alloys containing more than 15% Zn are susceptible to a dealloying process called Dezincification where the selective removal of Zn leaves a relatively porous and weak layer of Cu and Cu oxide.
