Many brasses are subject to dezincification, particularly hot stamping and die-casting brasses. The use of dezincification resistant brass usually solves this corrosion problem. This water meter body failed because the level of impurities was too high and changed the structure of the brass to one susceptible to dealloying. The use of a corrosion test to BS EN ISO 6509 would have demonstrated the unsuitability of this composition in aggressive waters.
