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.
