Merit
C18070 is a precipitation hardening copper alloy, which has high electrical conductivity, good strength, good bending properties, excellent cold and hot formability and good corrosion resistance. At the same time, due to the relaxation characteristics of the precipitate, it has excellent stress relaxation resistance, and the stress is also very good under the high temperature condition of 200 °C.
Applications
Main applications are electric vehicles, hybrid applications, electrical contacts, automotive connectors, photovoltaic systems and electronic components.
