3. Characteristic of C17300 Tube
High strength, high conductivity, high fatigue resistance, high wear resistance, non-magnetic

4. Application of C17300 Tube
It is mainly used for 5G base station, coaxial connector, photomultiplier tube, high precision instrument, military aerospaceCopper beryllium alloys feature high strength and good thermal and electrical properties. Two main types of copper beryllium alloys are high conductivity alloys and high strength alloys. The high conductivity alloys have 0.2-0.7% of beryllium and high cobalt and nickel contents. The wrought high strength alloys consist of 1.6 to 2.0% of beryllium and nearly 0.3% of cobalt. While, the cast high-strength alloys contain up to 2.7% of beryllium. The UNS designations of the cast alloys are C82000 to C82800 and that of wrought alloys are C17200 to C17400. The copper beryllium alloys can be precipitation hardened or age hardened to improve its strength. The tensile strength of C17300 alloys is over 1380 MPa (200 ksi).
