A fusible alloy is a metal alloy capable of being easily fused, i.e. easily meltable, at relatively low temperatures. Fusible alloys are commonly, but not necessarily, eutectic alloys. Sometimes the term "fusible alloy" is used to describe alloys with a melting point below 183 °C (361 °F; 456 K). Fusible alloys in this sense are used for solder.
Cerrosafe is a fusible alloy with a low melting point.It is a non-eutectic mixture consisting of 42.5% bismuth, 37.7% lead, 11.3% tin, and 8.5% cadmium that melts between 70 °C (158 °F) and 88 °C (190 °F).
Field's metal, also known as Field's alloy, is a fusible alloy that becomes liquid at approximately 62 °C (144 °F). [1] It is named after its inventor, Simon Quellen Field. [ 2 ] It is a eutectic alloy of bismuth , indium , and tin , with the following mass fractions : 32.5% Bi, 51% In, 16.5% Sn.
Wood's metal, also known as Lipowitz's alloy or by the commercial names Cerrobend, Bendalloy, Pewtalloy and MCP 158, is a metal alloy that is useful for soldering and making custom metal parts, but its fumes are toxic, as well as being toxic on skin exposure. The alloy is named for Barnabas Wood, who invented and patented the alloy in 1860.

Newton's metal is a fusible alloy with a low melting point. Its composition by weight is 8 parts bismuth, 5 parts lead and 3 parts tin; its melting point is 97 °C. Newton's metal is comparable to Cerrobend, but avoids its toxic cadmium content. This has encouraged its use for medical applications for easily shaped shielding during radiotherapy ...
Fusible alloys present a precipitation hardening (aging), so the mechanic properties will be dependent of the melting conditions, solidification rate, time since the melting, and the conditions in which the alloy will be used. Hence the advantages of the Bi-In alloy, when compared to the traditional ones based on Sn or Pb, is a larger thermal ...
It was used to secure cast iron railings and balusters in pockets in stone bases and steps. Does not contract on cooling. Bi 46 Sn 34 Pb 20: 100: 105 [16] Pb: No: Bi46: Sn 48 Bi 32 Pb 20: 140: 160 [17] Pb: No: For low-temperature soldering of heat-sensitive parts, and for soldering in the vicinity of already soldered joints without their ...
