Bismuth is a heavy metal produced as a flame retardant synergist in plastics, coatings, and polymer composites. Bismuth's high density and thermal stability make it deeply effective in reducing flammability and smoke generation in halogenated and halogen-free system environments. There are specific chemical properties as it Oxidizes slowly when heated, forming bismuth oxide (Bi₂O₃) and reacts with halogens (Cl₂, Br₂, I₂) to form bismuth halides. Also referred to as (Wismut, Bismuth Metallicum), it is supplied in technical grade for industrial flame retardant formulations along with other grades: pure bismuth, high-purity bismuth, commercial-grade bismuth and bismuth powder/granules/ingots. We are the trusted bismuth suppliers worldwide, with reliable lead times and global supply capability.
Bismuth is a dense, brittle, metallic element with a silvery-white appearance and a slight pink hue. It is atomic number 83 and atomic weight of around 208.98 g/mol. Bismuth is available i multiple forms such as bismuth powder, bismuth needles, bismuth shots, and bismuth ingots. We offer bismuth powder in bulk, and other forms can be supplied upon request. Bismuth is widely used in pharmaceuticals, low-melting alloys, cosmetics, electronics, and industrial formulations. As a trusted Bismuth manufacturer in the USA, Scimplify supplies high-purity bismuth (≥99.99%) in bulk, catering to the needs of U.S. industrial buyers. We ensure consistent purity, controlled particle size, and reliable supply for OEMs, formulators, and chemical distributors. Our Bismuth powder meets major U.S. compliance standards, listing with COAs, SDS, and technical documentation for hassle-free import and manufacturing use. Scimplify offers competitive bismuth pricing with stable supply and optimized logistics for U.S. buyers.

Chemical Properties & Specifications
Bismuth is used as a non-toxic substitute for lead in brass, steel, and other free-machining alloys. The use of bismuth in "lead-free" plumbing components increased after U.S. lead-content restrictions because of its similar density and favorable casting properties.
Bismuth is used to manufacture bismuth salts, including bismuth subsalicylate, which is widely used in gastrointestinal medicines. U.S. pharma companies source bulk bismuth from bismuth manufacturers like scimplify ensure consistent purity and safety.
Bismuth is a key component in thermoelectric materials (e.g., bismuth-antimony alloys) used for energy conversion and cooling applications. It is also employed in magnetic sensors and niche electronic devices due to its diamagnetic behavior and stability.
U.S. manufacturers rely on bismuth metal suppliers for catalyst-grade bismuth used in organic synthesis, polymerization, and eco-friendly catalytic systems. Bismuth-based catalysts (especially bismuth oxides or metals) are used in environmental catalysis. For example, the oxidative coupling of methane, or in organic synthesis, for "green" processes.
Bismuth is employed in pearlescent pigments (like bismuth oxychloride) to create shimmer and luster in decorative coatings, glass, and cosmetic products, and is also used in specialty heat-absorbing and UV-reflective metal coatings, particularly in performance materials.
