Bell metal is a type of bronze, primarily composed of copper and tin, known for its excellent acoustic properties. It is traditionally used to make bells, gongs, and other musical instruments due to its ability to produce a clear, resonant sound. The specific ratio of copper to tin can vary, but it typically contains around 20-25% tin. This alloy has been used for centuries in various cultures around the world. The production of bell metal involves careful casting techniques, often resulting in intricate designs. Its durability and tonal qualities make it a preferred material for artisans and musicians alike.
