Bismuth bronze or bismuth brass is a copper alloy which typically contains 1-3% bismuth by weight, although some alloys contain over 6% Bi. This bronze alloy is very corrosion -resistant, a property which makes it suitable for use in environments such as the ocean.

The high leaded tin bronzes contain the most widely used bearing bronze alloy C932 (also known as SAE 660). Widely available and somewhat less expensive than other bearings alloys – it is known for its unsurpassed wear performance against steel journals.

Jun 19, 2024 · Discover the advantages of bismuth bronze, a lead-free alloy with a combination of copper, tin, and bismuth. Learn about its properties and applications.

Sep 25, 2024 · Bismuth Bronze is a type of copper alloy where lead-free bismuth metal is incorporated, often with tin, primarily for industrial purposes such as bismuth tin bronze. It is a valuable replacement over lead-containing bronze alloys in terms of performance characteristics, without the hazardous effects due to lead.

Aug 15, 2023 · Bronze is a copper-based alloy that has been valued throughout history for its versatility, durability, and attractive nature. Bronze is composed primarily of copper with various combinations of tin, zinc, lead, and aluminum. This combination also produces brass.

Apr 18, 2024 · Bismuth Bronze Often used as an alternative to Leaded bronze, the addition of Bismuth gives the free machining and high wear resistance of Lead-Bronze, without the toxicity. This makes Bismuth Bronze grades such as C89835 perfect for plumbing applications.

Jan 3, 2024 · Bismuth bronze, sometimes referred to as lead-free bronze or lead-free brass, addresses issues with recycling and the harm that comes with lead-based bronzes. It usually contains 87–91% copper, 1–6% bismuth, 1% nickel, 2–4% tin, and zinc. It is still as machinable and workable as leaded bronze.

Bismuth bronzes have high thermal conductivity, are corrosion resistant, safe to use for drinking water applications, and interchangeable with older alloys, meaning bismuth bronze can be used to replace non-compliant parts.
