Low Melt/Fusible Alloys
Fusible Alloys & Ingots
Rotometals supplies a variety of low-melting-point metals that contain a mixture of bismuth, lead, tin, cadmium and/or indium. Also known as cerro metal alloys, these alloys expand only ~3.3% of their volume when changing from liquid to solid form, making them ideal for many industrial applications. They are often used for casting, tube bending, fixturing, machining parts for soft metal dies, anchoring parts, toggle dies and supporting castings and interrupted cuts.
Most of our low-melting, fusible alloys are cast into square ingots measuring approximately 2-3/8" x 2-3/8" x 5/8" . The product names we use are the approximate melting temperatures in degrees Fahrenheit, as they have no definite melting point. These alloys are normally used in gravity casting, but they also can be used in other casting methods.
No matter what type of eutectic alloys you're searching for, Rotometals has the best prices for low-melting, fusible metals on the market. Rotometals is the largest USA-made fusible alloy supplier for a broad range of Tool & Die applications. Take a look at our complete collection for more details, and feel free to contact us today if you have any questions! We're always happy to help you find the right materials for your specific project.
