Bellmetal
Bellmetal is a type of bronze, an alloy primarily composed of copper and tin, specifically formulated for casting bells. The typical composition ranges from about 75% to 80% copper and 20% to 25% tin, though variations exist. This precise ratio is crucial for achieving the desired acoustic properties. The tin content increases the hardness of the copper, making it more resonant and producing a clear, sustained tone when struck.
The production of bellmetal involves melting the constituent metals together in a furnace at high temperatures.
Historically, bell casting was a highly skilled craft, with foundries developing their own proprietary recipes and
