Patented Aug. 18, 1953 I I,
UNITED STATES PATENT OFFICE CADMIUM-FREE LOW FUSING POINT ALLOY Albert A. Smith, Jr., Metuchen, and John L. Everhart, Linden, N. J assignors to American smelting and Refining Company, New York,
N. Y., a corporation of New Jersey No Drawing. Application October 7, 1950, Serial No. 189,044
1 Claim. (Cl. 75134) 1 2 This invention relates to alloys and more par- References Cited in the file of this patent tioularly to low fusing point alloys. UNITED STATES PATENTS It is an object of the invention to provide cadmium-free, low melting point alloys. Number Name Date In accordance with the invention, alloys are 5 2213,153 y Oct. 15, 1940 provided comprising, by weight, 32-34% Bi, OTHER REFERENCES 42-44% In, 7-8% Pb and 15-18% Sn, and have fusing points of approximately 59 C.
It will be observed from the compositions that these alloys do not contain cadmium and, accordingly, they are particularly suitable for certain Fusible Alloys Containing Tin, September appl1cat1ons as heat transfer media where v v 1949, 24 pages, page 3 relied on. Published by cadmmn? be .detnmental' the Tin Research Institute, Columbus, Ohio.
