Mechanical Properties of C17300 beryllium copper

Through solid solution + aging heat treatment, the mechanical properties of C17300 beryllium copper have been significantly improved: 
Tensile strength: Approximately 500 - 700 MPa in the annealed state, and up to 1100 - 1400 MPa after aging treatment. 
Yield strength: Approximately 200 - 400 MPa in the annealed state, and increases to 900 - 1200 MPa after aging. 
Strain rate: In the annealed state, it is 10% to 25%, and after aging, it drops to 3% to 10% (still superior to most high-strength alloys). 
Hardness: The aged Rockwell hardness (HRC) can reach 35 to 42. The surface can be further strengthened for wear resistance through coating. 
Elastic modulus: Approximately 128 GPa. High rigidity makes it suitable for springs and elastic components.

Physical Properties of C17300 beryllium copper

Density: Approximately 8.25 g/cm³, lying between pure copper and steel, making it suitable for lightweight and precision components. 
Melting point: Approximately 865°C to 980°C. It can maintain structural stability even at high temperatures. 
Conductivity: The conductivity is approximately 22% - 28% of pure copper (according to IACS standards), suitable for high current density applications. 
Thermal conductivity: The thermal conductivity reaches 100 W/(m·K), suitable for applications requiring efficient heat dissipation. 
Coefficient of thermal expansion: 17.5×10⁻⁶/℃ (20°C - 300°C), low expansion property is suitable for precision instruments. 
Magnetic property: Non-magnetic. Suitable for electronic shielding or environments with magnetic sensitivity.
