Process	Bronze/brass & other alloys plating Alloys-platings are used when properties which cannot be spontanousely aquired by the pure metal coatings are required. Two or more metals fall simultaneously to the cathode. Control of the bath chemistry and alloys' composition is very expensive. The most common alloys are: brass (Zn-Cu 70%) for decoration and for improving the adhesion between steel and rubber; Cu-Sn (90% Cu, bronze), against adhesive wear, high costly; Cu (40-45%), corrosion resistance; Pb-Sn, Sn (6%), for corrosion protection; Sn (60%), soldering metal; Ni-Fe(40%) to replace Ni when too costly; Ni-Sn (65%), for corrosion resistance even in very highly acid environments.

Price notes	The first price on the cell refers to bronze-plating, the second one to brass-plating. Over 5000 parts the price doesn't vary so much. The price is calculated for typical average thichnesses: 15 micron (bronze); 3 micron (brass).
Environmental notes	In many cases it is used a cyanogen electrolyte, therefore very poisonous.
Additional info	All alloys-plating processes are very costly because they require very expensive equipment and professional staff. Labour is the most important factor for pricing.
