Bismuth RT (Radiation therapy) alloys are offered in cadmium-free, low-melting versions (down to 158°F) that can be formed into custom-shaped shielding blocks and eliminate danger of lead's high melting point/toxicity. Materials can also be used as substitute for lead as heat-transfer medium, protecting melting pot from zinc's corrosive effects during galvanizing process. Other uses include addition to lead, tin, and solder alloys to lower melting point or increase casting ability.

Belmont Bismuth Alloys Now Offer an Alternative to Lead Shielding.
Belmont Metals offers the largest variety of non-ferrous metals than any other U.S. manufacturer. Belmont Introduces a special line of RT (Radiation therapy) alloys that replace lead shielding.
We also now offer cadmium-free alloys. These low melting alloys (as low as 158 degrees Fahrenheit) are formed into custom shaped shielding blocks for each patient using a single double boiler, etc. Thereby avoiding the danger of pure lead's high melting point and toxicity. Bismuth is an excellent substitute for lead as a heat-transfer medium, protecting the melting pot from zinc's corrosive effects during the galvanizing process. Where lead cannot be totally eliminated (in tempering baths for steel wire, tools, etc.), Bismuth is added to lower the temperature, thus reducing lead fume.
Also, bismuth is added to lead, tin, and solder alloys to make them more lustrous, easier to cast, and to lower the melting point.
Belmont introduces Bismuth; Elemental as high-purity or commercial grade, virgin 99.99%, 99.9%, bismuth based low melting alloys105-520F; Bismuth base low-temperature solders. Metallurgical assistance in product selection and application is available. We offer an extensive and diversified inventory, a variety of shapes, in any quantity.
