Belmont Metals, Inc. 136 Degree F Low Melting Alloy 2491A

Featuring 99.99% Indium and Indium-Based Low Melting Alloys

Indium was discovered by the German chemists Ferdinand Reich and Hieronymus Richter in 1863. Reich and Richter had been looking for traces of the element thallium in samples of Zinc order, when they saw a brilliant indigo line in the sample’s spectrum which revealed the existence of Indium. Indium is about as abundant as silver but is much easier to recover since it typically occurs along with Zinc, Iron, Lead, and Copper ores.

Indium has a wide range of uses: as a thin alloy layer in high performance bearings, in the electronics industry it has been widely used to manufacture flat screen televisions. It is used as a component of transistors and in computer equipment; in low melting point alloys and in solders. Some of these low melting point alloys are used for glass lens grinding and polishing, and as plugs for fire sprinkler systems. Indium is also used as catalysts and in the purification for the manufacture of certain organic chemical products, particularly man-made fibers. The metal also has many minor uses in research and laboratory techniques.

Bismuth Alloys

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,

Category 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.

Category 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.
