Eutectic alloys and non-eutectic alloys are categories when discussing low melting alloys. Low melting alloys require lower temperature ranges to melt, anywhere from 40 degrees to 300 degrees Fahrenheit. This property allows for the alloys to be melted at lower temperatures without damaging or impacting other nearby materials or surfaces that the low melting alloy…
Featuring 99.9% Bismuth and Low Melt Eutectic and Non-Eutectic Alloys offering custom compositions and forms
Bismuth is a white, crystalline, brittle metal with a pinkish tinge. It s the most naturally diamagnetic element and has one of the lowest values of thermal conductivity among metals. Bismuth is 86% as dense as Lead and has long been considered as the element with the highest atomic mass that is stable. It is available as commercial-grade or high purity,
Applications:
It can be used as a carbide stabilizer in the manufacturing of malleable Iron, as an additive to low-carbon steel or aluminum to improve machinability, and as a dense material for fishing sinkers. Bismuth as an alloying element can be used in the production of fusible alloys ( low melting point alloys ) and Bismuth based low temperature solders. Standard and special compositions are Bismuth alloyed with either Antimony, Cadmium, Copper, Indium, Lead or Tin.
Forms:
Bismuth is offered in a variety of forms such as Ingot, Lumps, Shot, Granular, Powder, Pellets or Needles. Bismuth Alloys are available in various sizes as well including Bar, Cakes, Cast Shapes, Ingot, Granular, Shot and Sticks. Special shapes are also available.

Bismuth is a white, brittle metal with a slight pink color and is typically recovered as a by-product of lead and copper. It is commonly used as an alloying element for various low melting alloys where it is mixed with other metals such as Lead, Tin, or Cadmium. It is also used as well for a lead substitute in other materials. The Ingots are our largest size available and have a purity of 99.99% and often serve as grain refiner in the foundry industry as well. Our regular bars can be used in solder applications as a replacement for Lead since it is non-toxic. Our 1/8" & down shot product allows you to make smaller additions during your casting process and has a purity of 99.9%. Forms: - Slabs
