Copper alloy wire C9 series

for aeronautics

C97® is a free-machining heat-treated leaded copper nickel alloy offering both high mechanical strength and electrical conductivity. C97® is primarily used for connectors components: it is perfectly suited for use in harsh environments presenting both high temperature and high mechanical solicitation. In addition, C97® is a more eco-friendly alternative to beryllium and cadmium copper alloys. Connectors for Aerospace and Automotive industries: C97® is used for female contact body in circular or RF connectors. C97® demonstrates outstanding thermal stress relaxation resistance allowing it to better support high temperatures and high vibrations specific to these industries, providing a longer service life of the connector compared to connectors made of other alloys. Connectors for medical devices: C97® is used for female contact body for specific connectors used in medical devices. For such applications, C97® demonstrates excellent fatigue resistance, allowing it to support daily mating cycles providing a longer service life of the connector compared to other alloys. Limited stress relaxation Thermal stress relaxation represents the stress decrease over time in a connector under outside solicitation in a high temperature environment: thus, the decrease must be limited in order to preserve the contact force of the connector. C97® presents one of the best thermal stress relaxation resistance compared to other copper alloys (such as brass and copper-beryllium) with very high levels of remaining stress after exposure in high temperatures environments.
