Wood tungsten alloy
Properties and composition
Alloy Wood — a low-melting heavy alloy, which invented by Robert Williams Wood. alloy density is 9.72 g / cm³, a melting temperature of 68,5 ° C. It consists of 25% Pb, 12,5% Sn, 50% Bi, and 12,5% Cd cadmium. There are other variations of such an alloy developed later. Most fusible alloys during solidification shrink, and containing more than 55% of bismuth during solidification, conversely, expands. Williams Wood managed to find a «middle ground», a part of which remains virtually unchanged in volume. Alloy Tensile Strength — 4.5 kgf / mm 2; Tensile elongation — 7%; Brinell hardness of 10.5 kgf / mm 2.
Wood’s alloy is a silvery-white sticks or pellets. It comes in the form of bars 10×12×250 mm, in ingots, granules, ingot in accordance with GOST and TU (technical conditions) 6−09−4064−87. Warranty period of storage should not exceed three years.
Wood’s alloy is used as rods melted in a precision casting, a thin-walled bending operations of pipes, the method for manufacturing electroformed hollow bodies. Such alloys are indispensable as solders for snapshots in fuses to safety devices for mounting casting parts. This alloy is designed for non-metals by electrolytic coating: Tin — bismuth, tin-lead and silver, and copper brazing.
It is used for soldering Thermal Cutoff and fuse links.
