Bronze has the highest corrosion resistance of all copper alloys and has excellent wear and fatigue resistance as well as very good sliding properties. However, the conductivity is somewhat lower than that of brass parts.
With bronze contacts, the stress relaxation at higher temperatures is less pronounced than with brass contacts. This means that a connector can operate at higher temperatures when using bronze contacts.
