Fusible

[Fr., from Lat. fusibilis, from fundere, fusum, to pour out, to melt.] That may be melted or liquefied. Fusible Metals. (Chem.) Many of the alloys fuse at a temperature le than that required to melt the most fusible of their constituent metals. Thus a mixture of 8 parts bismuth, 5 of lead, and 3 of tin, melts below 2120. One of 3 parts cadmium, 15 bismuth, 8 lead, and 4 of tin, fuses at 140° F. As they expand on cooling, they are of great use to the die-sinker, who is enabled to take a sharp cast of his work at a comparatively low temperature. The first of these alloys has been obtained in crystals, thus proving that it is a true chemical compound.
