Cerrotru and Low-melt Alloys

Standard Cerro or Low-melt alloys go by the trade names: Cerrotru, Cerrobend, Cerrocast and Cerrolow although there are many others. Cerro or Low-melting Alloys contain a mixture of bismuth, lead, tin, cadmium and/or indium. These alloys expand only ~3.3% of their volume when changing from liquid to solid form, making them ideal for many hobbyist and industrial applications. They are often used for wood inlays, tube bending, machining parts for soft metal dies, anchoring parts, and supporting castings and interrupted cuts.
