LOW MELT ALLOYS or FUSIBLE ALLOYS

What are Fusible Alloys?

  • Alloys containing bismuth, other elements are lead, tin cadmium and indium
  • Fusible alloys can expand by 3.3% volume when setting from liquid to solid
  • Fusible alloys have unusually low melting temperatures

Common Uses for Fusible Alloys

 

  • Work holding: tube and pipe bending, aircraft applications
  • Medical Field: blocking for radiation therapy
  • Molds: dental application, plaster, plastics and encapsulating
  • Solder: safety devices used in fire protection equipment
  • Transportation: plugs in compressed gas tanks for large trucks
