TinCharacteristics: Tin is a silverywhite, soft, malleable metal that can be highly polished. Tin has a highly crystalline structure and when a tin bar is bent, a 'tin cry' is heard, due to the breaking of these crystals. In compounds tin is usually in the divalent state (Sn 2+) or tetravalent state (Sn 4+ ).
Characteristics and Properties of Copper and Copper Alloy ...Copperlead alloys containing about 30% lead are stronger but have less satisfactory surface properties and are usually used with a thin leadtin overlay. If the copperlead alloys do not have sufficient loadcarrying capacity, the lead content is reduced, and tin is added to improve the strength. Typical is a 74Cu22Pb4Sn composite.
