Description Of Beryllium Copper Tube
Beryllium Copper Tube in C17200 (also known as Alloy 25) is a high-performance copper alloy tube manufactured to ASTM B643 standard. C17200 contains 1.8–2.0% beryllium with the balance being copper. This alloy offers an exceptional combination of high strength, excellent electrical and thermal conductivity, and outstanding corrosion resistance, making it the most widely used beryllium copper alloy.
C17200 beryllium copper achieves its high strength through precipitation hardening (age hardening). After solution annealing and aging, the alloy develops tensile strength up to 1,400 MPa and hardness up to 40 HRC, while maintaining electrical conductivity of 22–28% IACS. This unique combination of properties makes C17200 ideal for applications requiring both high strength and good conductivity, such as springs, electrical connectors, and precision instruments.
Beryllium copper tubes are available in a range of tempers including TD04 (cold drawn + aged) and TF00 (solution annealed + aged), with custom outer diameters, wall thicknesses, and lengths available upon request. Typical applications include springs, connectors, switches, relays, and precision instruments.
