BRONZE

Bronze
Bronze is an alloy of metal that is copper based with tin as the main additive. Some tins, though, can have phosphorus, manganese, aluminum, or silicon as the main alloying ingredient. Bronze is typically strong, tough, and corrosion resistant with high electrical and thermal conductivity.
SAE 660
The most commonly used bronze in bushing and bearing applications, it is easy to
machine and provides long life in applications where wear is an issue.
