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).
Fusible alloys are typically made from low melting metals. There are 14 low melting metallic elements that are stable for practical handling. These are in 2 distinct groups: The 5 alkali metals have 1 s electron and melt between +181 (Li) and +28 (Cs) Celsius; The 9 poor metals have 10 d electrons and from none (Zn, Cd, Hg) to three (Bi) p electrons, they melt between -38 (Hg) and +419 (Zn ...
Vacuum grade. For ferrous and nonferrous alloys in moderate temperature vacuum systems. Slightly sluggish. Tends to liquate. Can be used without flux in hydrogen, inert gas, or vacuum. Indium improves wetting of ferrous alloys. Silver-white color. Lowest melting point from ductile low-vapor pressure alloys. 24: 61.5: In 14.5: Ag 63 Cu 27 In 10 ...
Good fatigue resistance combined with low melting point. Reasonable shear strength and fatigue properties. Combination with lead-tin solder may dramatically lower melting point and lead to joint failure.

The elements bismuth and indium have relatively low melting points when compared to other metals, and their alloy bismuth–indium (Bi–In) is classified as a fusible alloy. It has a melting point lower than the eutectic point of the tin–lead alloy. The most common application of the Bi-In alloy is as a low temperature solder, which can also ...
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).
Many bismuth alloys have low melting points and are found in specialty applications such as solders. Many automatic sprinklers, electric fuses, and safety devices in fire detection and suppression systems contain the eutectic In 19.1 -Cd 5.3 -Pb 22.6 -Sn 8.3 -Bi 44.7 alloy that melts at 47 °C (117 °F) [ 19 ] This is a convenient temperature ...
The alloy is named for Barnabas Wood, who invented and patented the alloy in 1860. [1] [2] It is a eutectic, fusible alloy of 50% bismuth, 26.7% lead, 13.3% tin, and 10% cadmium by mass. It has a melting point of approximately 70 °C (158 °F). [3] [4]
