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.
Rose's metal, Rose metal or Rose's alloy is a fusible alloy with a low melting point. Rose's metal consists of 50% bismuth , 25–28% lead and 22–25% tin . Its melting point is between 94 and 98 °C (201 and 208 °F).
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.
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 ...

The proportion of iron oxide is low due to its reduction with cobalt. The bond strength is highly dependent on the oxide layer thickness and character.[4][6] The presence of cobalt makes the oxide layer easier to melt and dissolve in the molten glass. A grey, grey-blue or grey-brown color indicates a good seal.
Thermal fuses are usually found in heat-producing electrical appliances such as coffeemakers and hair dryers. They function as safety devices to disconnect the current to the heating element in case of a malfunction (such as a defective thermostat) that would otherwise allow the temperature to rise to dangerous levels, possibly starting a fire.
The two Fernico alloys both consist of iron (Fe), nickel (Ni), and cobalt (Co). Fernico is used at high temperatures (20 to 800 °C) and is identical to Kovar. Fernico II is used at cryogenic temperatures in the -80 .. -180 °C range. Both are used to create electrically conductive paths through the walls of sealed borosilicate glass
