Another example is graphitisation of cast iron.
Cast iron has a structure comprising essentially two components - graphite and ferrite.
The dezincification of brass is a little more complicated since the zinc and copper are not present as separate constituents but as alpha and beta solid solutions. The result therefore is to remove the zinc as corrosion products and leave a residue of copper. Dezincified brass, like graphitised cast iron, retains the original shape and dimensions of the metal component before corrosion but in both cases, the residue is porous and has very little strength. Alpha-brass strip is not usually arsenical since it is mostly used in situations where dezincification does not occur or is not significant. Dezincification as a problem with alpha-beta brass water fittings in some districts was first recognised in the late 1950's.
