Description
Bismuth Metal Product Overview
Bismuth (Bi) is a brittle, silvery metal with a pinkish tint that melts at about 271°C. Unusually, it expands when it solidifies, and it is one of the least toxic heavy metals, which makes it a common replacement for lead.
In addition, alloy producers use bismuth in low-melting fusible alloys for fire sprinklers, safety plugs and casting, and in lead-free solders. Similarly, metal producers add it to steel and aluminium for free-machining grades, and chemical producers use high-purity bismuth to make compounds such as Bismuth subsalicylate and Bismuth (III) oxide. It also serves in thermoelectric materials such as Bismuth telluride.
Furthermore, granules, needles and powder suit different melting and blending processes. Other bismuth compounds in our range also include Bismuth Nitrate Pentahydrate and Bismuth (III) citrate.
Key Applications of Bismuth Metal
Typical uses include, for example:
🔥 Fusible Alloys
Low-melting alloys for sprinklers as well as safety plugs.
🔌 Lead-Free Solders
Alloying element in solders.
🔩 Free-Machining Alloys
Additive for steel as well as aluminium.
🧪 Bismuth Chemicals
Raw material for pharmaceutical bismuth salts.

⚠️ Safety & Handling: Massive metal has low hazard; fine powder may be flammable and may irritate the eyes and respiratory tract. Avoid dust formation and ignition sources, and also wear dust protection and eye protection. Store in tightly closed containers in a dry place. Always consult the Safety Data Sheet (SDS), because it contains the full classification and handling instructions.
Frequently Asked Questions
Why is bismuth used instead of lead?
Because it has similar density and low melting alloys but is far less toxic, it replaces lead in solders, shot and alloys.
Which forms do you supply?
Granules, needles, ingots as well as powder in 99.99% to 99.999% purity.
How can I get a price and documents?
Prices depend on quantity, packaging and destination, so please contact us with your required volume. We then send a quotation together with the CoA and SDS.
