It can be brazed and soldered easily. It is typically used as springs, bellows, and electrical hardware. Bronze is an alloy of copper which can vary widely in its composition. It is often used where a material harder than copper is required, where strength and corrosion resistance is required and for ornamental purposes. The variations in bronze (both in proportion and elemental composition) can significantly affect its weathering characteristics. "True" bronze is a combination of approximately 90% copper (Cu) and 10% tin (Sn), however there are three major classes or types of "bronzes" used in sculpture and construction.
