Bleisalze
Bleisalze, also known as bismuth bronze, is a type of bronze alloy that contains bismuth as a primary constituent. The term "bleisalze" is derived from the German words "blei" meaning lead, and "salz" meaning salt, reflecting the historical use of bismuth salts in its production. Bismuth bronze is valued for its unique properties, including a lower melting point compared to traditional bronze, which is around 70% copper and 30% tin. This makes it easier to cast and work with, particularly in the production of small, intricate items.
The addition of bismuth to bronze enhances its machinability and corrosion resistance. Bismuth bronze is often
Historically, bismuth bronze was used in the production of coins and medals due to its resistance to
