Process	Copper- & tin-plating Copper is used to coat Zn, Al, and Mg, as first coating before further plating. It is used to improve the solderability of the named materials, decrease their electrical resistance, harden them against abrasive and adhesive wear. Cu-plating is a part of the chrome-plating process of plastics. It is also used for decoration. Tin is used to plate steel components already coated by Ni or Cu, against corrosion; steel plates for the conservation industry; and for improving the solderability of surfaces in the electronic industry. Basic and acid electrolytes are used.

Price notes	The first price on the cell refers to copper-plating, the second one to tin-plating. Over 5000 parts the price doesn't vary so much. The price is calculated for typical average thichnesses: 25 micron (Cu); 7 micron (Sn).
Environmental notes	Tin is unpoisonous.
Additional info	The cost of tin is relatively high. Labour is the most important factor for pricing.
