Wood’s Alloy


a fusible alloy based on bismuth. Wood’s alloy consists of 50 percent Bi, 25 percent Pb, 12.5 percent Sn, and 12.5 percent Cd. Its melting point is 68° C. It has good casting properties and easily takes on the smallest details of a form. The limit of its shearing strength is 0.5 Mnewtons/m2, and its specific elongation is 25 percent. Wood’s alloy is used to make models, coatings of metallo-graphic grinding edges, and other goods.
