- Thermal expansion coefficient: 17.5×10⁻⁶/℃ (similar to silicon chip, suitable for electronic packaging)
- Heat resistance: It can still maintain the tensile strength of more than 600 MPa at 300℃, which is suitable for high temperature environment.
The outstanding advantages of C17300
It is difficult for ordinary copper alloys to meet high strength and high conductivity at the same time, and the C17300 balances these two points perfectly through the addition of beryllium and cobalt, which is especially suitable for high-load and high-current application scenarios.
The precipitation strengthening of beryllium makes the material have very high wear resistance, which is suitable for the manufacture of springs, bearings and other parts that need to withstand friction for a long time.
Easy to cut, press and form, excellent surface treatment performance, suitable for the manufacture of complex shapes of precision parts.
Stable performance in humid, high temperature or chemical corrosion environment, long service life.
The main application areas of C17300
It is used to manufacture high-precision components such as connectors, relays and switches to ensure the stability and reliability of signal transmission.
Manufacturing sensors, high voltage relays, charging pile contacts, etc., to meet the stringent requirements of high temperature and high current.
Used to manufacture fasteners, springs, bearings and other key components, with lightweight, high strength characteristics.
Manufacturing mold, electrode, welding, etc., wear resistance, high temperature resistance, extend the service life of equipment.
Used for fuel cell bipolar plate, wind power conductive slip ring, etc., to meet the needs of high conductivity and corrosion resistance.
Environmental protection and safety of C17300
- The content of beryllium is low (1.8%-2.0%), and strict protective measures are taken during processing to ensure safety.
- The material can be recycled 100%, in line with RoHS, REACH and other environmental standards.
