Tin Plating

 

a layer of tin applied to the surface of metal objects, including radio components and cookware, to protect against oxidation. The process is usually accomplished by immersing the object in a bath of molten tin or by an electrolytic method (seeELECTROPLATING TECHNOLOGY). In tin plating used to coat cookware and similar items, the content of undesirable impurities (Pb, As) must be minimal. For cookware, the amounts tolerated are usually < 0.25 percent Pb (by weight) and ≤0.015 percent As; for food cans, ≤0.025 percent Pb and ≤ 0.01 As.
