Bell clappers are cast with a softer metal, so the wear occurs to the clapper, which is easy & inexpensive to replace, whereas, the wear of the inside of the bell, negatively affects bell longevity.

For bronze bells, iron alloy bells sound the bell with a brighter sound, and bronze clappers sound a bell with a mellow sound. Each carillonneur has a preference.

The more round a clapper is, the clearer the sound produced is.

Cast iron bells are purely noise makers, i.e. an iron bell has no specific musical note propduced and no specific musical partials. The flatter the clapper, the more surface area vibrations produced. The larger the cast iron bell, the heavier the bell vibrations, thus the farther the sound would travel.
