Explanation
Bell metal is an alloy of copper and tin, about 78–80% copper and 20–22% tin. It is a kind of bronze with extra tin, which makes it hard and gives the clear, ringing sound used for bells and utensils.
Other copper alloys: brass (copper and zinc), bronze (copper and tin, with less tin), gun metal (copper, tin and zinc) and German silver (copper, zinc and nickel).
