Brasses are alloys between copper and zinc (zinc between 10 and 40%) and, whilst their applications have declined, they are still important. Brass is in fact the oldest application for zinc. The characteristics of brasses are good corrosion resistance and good mechanical properties. Traditionally brasses have been used in marine applications, in engineering, for household fittings and for decorative items, the latter uses being enhanced by the natural appeal of brass i.e. its warm colour and feel.
