Bronze Bells Product Description:
Bronze used for making bells and gongs is essentially an alloy of copper and tin. Copper containing about 22-24 wt% of tin is often known as bell metal because it has a pleasing sound quality when struck. Bell bronze, also known as bell metal, is the traditional alloy used for fine cymbals, many gongs, and, as the name suggests, bells. It is normally stated to be one part tin to four parts copper, that is 20% tin, and this is still the most common formula, but there has always been some variation. Larger and smaller bells are cast with differing amounts of tin, and some bell, gong, and cymbal makers use small but significant amounts of other elements, notably silver, gold, and phosphorus. Bell bronze is a two-phase alloy, meaning some of the tin is not dissolved in the copper grains but exists between them. This makes the metal harder and more brittle than a single-phase alloy, and also affects the way the metal responds to hardening by hammering and lathing, and greatly restricts the use of mechanized techniques of manufacture.
