The corrosion resistance of low zinc yellow brass showed significant improvement with increasing additions of aluminium to the alloy, as evidenced by data on corrosion rates obtained from corrosion currents, amounts of zinc released, and loss in weight of samples. All of the alloys in the permanent mould cast condition showed greater resistance to dezincification than did sand cast alloys. Low zinc yellow brass and high zinc yellow brass showed the highest resistance to dezincification as evidenced by data on pit depths.
