Vuda tungsten alloy

Properties and Composition

Wood's alloy is a fusible heavy alloy invented by Robert Williams Wood. The alloy has a density of 9.72 g/cm³ and a melting point of 68.5°C. It contains 25% Pb, 12.5% Sn, 50% Bi and 12.5% Cd cadmium. There are also other variants of such an alloy developed later. Most of the light-melting alloys shrink during solidification, while those containing more than 55% bismuth, on the contrary, expand during solidification. Williams Wood found a "golden mean", a composition that barely changes in volume. The alloy's tensile strength is 4.5 kgf/mm2; tensile elongation is 7%; Brinell hardness is 10.5 kgf/mm2.

Production

Wood Alloy is a silvery-white stick or pellet. It is produced as rods 10×12×250 mm, in ingots, pellets, ingots in accordance with GOST and TU (technical conditions) 6-09-4064-87. The deadline for storage should not exceed three years.

Application

Alloy Wood is used as melting rods in precision casting, in operations of bending thin-walled pipes, for producing hollow bodies by electroforming method. The alloys are indispensable as solder, for making casts, for fuses in safety devices, for fixing parts by casting. This alloy is designed for nonmetals with electrolytic coating: tin-bismuth, tin-lead and silver, as well as for brazing copper.
It is used for soldering thermal fuses and fuse links.
