Product Code : HP-Bi-7N5-CU
Bismuth is a brittle metal which is silvery in color with a pink tinge. It is stable in air and water. It has poor thermal and electrical properties and finds applications in the manufacture of fusible alloys, a range of materials with low melting points which are suitable for various applications including solders and thermal fuses. Pure bismuth shows a high absorbtion of gamma rays which makes it useful as a filter or window for these particles, whilst at the same time permitting the passage of neutrons.
ATT provides Bismuth metal and selenium compounds including:Bismuth metal powder, particle, block, plate, ingot, selenium sputtering target, etc. Purity: 2N to 7N5.

Product Information
Bismuth is a brittle metal which is silvery in color with a pink tinge. It is stable in air and water. It has poor thermal and electrical properties and finds applications in the manufacture of fusible alloys, a range of materials with low melting points which are suitable for various applications including solders and thermal fuses. Pure bismuth shows a high absorbtion of gamma rays which makes it useful as a filter or window for these particles, whilst at the same time permitting the passage of neutrons.
Bismuth is the most diamagnetic element, and its thermal conductivity is lower than any metal except mercury. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal except mercury. It has a high electrical resistance, and has the highest Hall effect of any metal (that is, the greatest increase in electrical resistance when placed in a magnetic field). Bismuth is stable to oxygen and water but dissolves in concentrated nitric air. All bismuth salts form insoluble compounds when put into water.
ATT provides Bismuth metal and selenium compounds including:Bismuth metal powder, particle, block, plate, ingot, selenium sputtering target, etc. Purity: 2N to 7N5.

Applications of Bismuth Metal
Production of bismuth alloys，With other metals such as tin, cadmium, and lead, bismuth forms low-melting alloys which are extensively used in the automotive and aviation industries, safety devices in fire extinguishing systems, and solders.
Production of welding electrode
Production of oil exploration charge
Manufacture of low melting solders and fusible alloys
Bismuth is also used in malleable irons, steels for free machining, and isostatic lead-bismuth eutectic (LBE) used in nuclear reactors. Alloys of bismuth are well-suited for the making of sharp castings of objects subject to damage by high temperatures. Bismuth metal is used as a thermocouple material, an electro catalyst for converting CO2 to CO for alternative fuels. Its soluble salts are characterized by forming insoluble basic salts with the addition of water, a property sometimes used in detection work. Industrial applications for compounds and alloys include solders, lead-free ammunition, additives for casting and galvanizing, lubricants, pyrotechnics, cosmetics, glazes and pigments, and catalysts for making acrylic fibers and high density foams. The most common medical use of bismuth is in the commercial digestive aid bismuth subsalicylate, more commonly known as Pepto-Bismol (57% bismuth by weight).
Packing of Bismuth Metal
Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.
ATTs’ Bismuth Metal is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
