Chung Metal stocks C17300 beryllium copper rod and bar, an alloy with greater strength potential than C17510 but which maintains useful conductivity. Controlled production and heat treatings by our facility give rods which provide superior performance and certification requirements. Customers in the electrical, precision tooling, and contact manufacturer applications use C17300 stock where strength and conductivity combinations are required.
C17300 typically has ~1.8–2.0% Be with complementary alloying elements (such as cobalt or nickel) to adjust properties. Tensile strength in aged state is up to ~1,100–1,300 MPa, yield similarly high. Hardness is high, although elongation is lower in high-strength tempers. Electrical conductivity is moderate — less than very soft copper but adequate for most applications (~20–40% IACS with respect to the temper). Fatigue strength and wear are high in well-processed bars.

Yes, Beryllium Copper C17300 bars can be welded, but it's important to use proper techniques, such as TIG or MIG welding, and ensure appropriate heat management to avoid material degradation.
Beryllium Copper C17300 bars offer excellent high-temperature performance, maintaining strength and hardness up to 400°F (204°C). They also resist thermal fatigue, oxidation, and corrosion, making them ideal for demanding environments.
Yes, Beryllium Copper C17300 rods can be customized in size and length according to specific requirements, providing flexibility for various applications, including manufacturing and precision engineering.
Applied to high-performance springs, electrical contacts and connectors, relays, electrode components, precision instruments, and miniature motors. Also in communications, aerospace, and sensor applications. C17300 rods are selected when conductivity needs to be maintained with good mechanical strength, for components under cyclic stress, dynamic loading, and where both durability and electrical performance are needed.
