School bells, and bells in general, are made of metals because metals possess the property of sonority. Sonority is the ability of a material to produce a clear, deep, resonant ringing sound when struck. This property is characteristic of many metals and alloys, especially when shaped appropriately into a bell. Malleability, ductility, and lustrousness are other properties of metals but are not the reason they are used for making bells that produce sound.
Metals are used for making bells because they are sonorous.
Bronze, a metal alloy (primarily copper and tin), is a historically common material for making high-quality bells due to its excellent sonorous properties.
