Description

Cerrobase is a low-melting alloy that contains bismuth and lead. It melts at 255° F (124° C). Cerrobase is a eutectic alloy that shrinks initially and then grows slowly. Cerrobase is used for: *Thermal fusibles: For forming or temporarily fixing parts *Eyewear: For manufacturing spatial parts *Aeronautics: For manufacturing spatial parts Cerrobase has the following properties: *Weight: 1 pound *Dimensions: 3" square x ¼" high *Density: 0.38 lbs./in3 *10.3 g/cc Low-melting-point alloys are also known as cerro metal alloys. They are made from a mixture of bismuth, lead, tin, cadmium, and/or indium. They expand only about 3.3% of their volume when changing from liquid to solid form. Some other low-melting-point alloys include: *Wood's metal/Cerrobend: Used for pipe and tube bending, low-temperature casting, and as a meltable valve element in fire sprinkler systems *Fuse wire: Made from an alloy of tin and lead
