Low Melt/Fusible Alloys - RotoMetals
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.
