Notes:
Copper and gold are the only two metals with any distinctive colour.
In consequence, brasses are extensively used for durable decorative applications and for the manufacture of functional items where aesthetic appeal is a requirement in addition to a long service life. Aluminium brasses have a distinctive silvery sheen and the addition of manganese to certain brasses gives them an attractive bronze colour when extruded. High tensile brasses, some of which are otherwise known as "manganese brasses" or previously "manganese bronzes" are particularly suitable for architectural applications since they can also be patinated to a range of durable brown and bronze finishes.
