A small ritual bell is cast bronze or brass in every tradition that uses one, but the traditions differ sharply in who is allowed to ring it, which turns out to be the more interesting variable than the metal itself.
Construction across traditions
A Catholic sanctus bell is a small cast handbell rung at the elevation during Mass, a Hindu temple bell is often larger, inscribed, and mounted at a doorway rather than carried, a Shinto suzu bell contains loose pellets that jingle rather than a struck clapper, closer in mechanism to a rattle than to a Western bell, and each is produced by foundries specific to its own tradition rather than a shared cross cultural supply chain.
Who is permitted to ring it
A Catholic sanctus bell is rung only by an assigned server at a specific moment in the liturgy, a restriction tied closely to the rite itself, while a Hindu temple doorway bell is typically rung by any devotee entering, a deliberately open gesture rather than a restricted one, and a Shinto shrine bell is likewise rung by any visitor as part of getting a kami's attention before praying. A cracked small ritual bell of any of these kinds is usually just replaced rather than repaired, unlike a large church or temple bell, which is valuable enough to be re-cast.
