Fusible Alloys

Fusible Alloys

Fusible alloys are metal alloys that melt at low temperatures, usually below 300º F or 150° C. Many fusible alloys have eutectic compositions and are often bismuth-based in combination with lead, tin, antimony, gallium, cadmium, zinc, and indium alloying constituents. Some fusible alloys are gallium-based or indium-based.

Fusible alloys are essentially stable and inert—especially when compared to metallic elements on the other side or periodic table (e.g. K, Na, Li). While alkali (Li, Na, K, Rb, Cs) and alkali earth (Mg, Ca, Sr, Ba) metals also have low melting points, alloys of these metals are usually excluded from the group of fusible alloys because of their unstable nature and reactivity. See below for source url.

Low melt/fusible alloys can come in the form of solid bars, ingots, powder, solid ribbon, wire and special forms. Check out the selection of the forms we have available on our site. We also have SDS sheets for all alloys we carry at our fusible alloys section here. You can also use our site search (at top right on website) for searching specific alloys by typing in for example "Indium".

Besides die casting for medical and electrical clamping and other standard applications, what cool stuff is being made from low melt alloys?
