Anucha Metals supplies strong Beryllium Copper C17300 Bars and Rods, designed for environments requiring strength, machinability, and corrosion resistance. Known as free-machining beryllium copper, C17300 shares similar mechanical properties with C17200 but has added lead for improved machinability. Manufactured in Bangkok, our C17300 bars conform to ASTM B196 and B441 standards, making them suitable for aerospace, defense, and electronics. Each bar or rod undergoes strict quality testing to ensure they meet dimensional and performance standards.
C17300 contains 1.8–2.0% beryllium, ~0.2–0.6% lead, and the remainder copper. It reaches tensile strength up to 1380 MPa after aging and electrical conductivity of ~20–25% IACS. The alloy provides excellent machinability, high hardness, great fatigue strength, and corrosion resistance. Lead enhances chip breaking and tool life during machining.

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.
C17300 bars and rods are ideal for electronic connectors, military-grade hardware, aerospace fittings, and instrument parts. In precision machining, it is used for valve seats, bushings, and intricate electrical terminals. Due to its wear resistance and non-sparking nature, it works in explosive environments and safety tools. The alloy’s machinability makes it a preferred choice for tight-tolerance parts in defense, energy, and industrial control systems.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
