From Hamilton, New Zealand, Hemi Metals is a trusted source for high-performance materials, supplying industry with premium Beryllium Copper C17000 bars and rods. We understand that your projects demand reliability and exceptional material characteristics, which is why we provide this high-strength alloy with a focus on consistent quality and local support. Our team is dedicated to ensuring you receive the right components to meet the rigorous demands of your manufacturing and engineering applications, right here from our base in the heart of the Waikato.
The makeup of C17000, also known as Alloy 165, is primarily copper with about 1.7% beryllium and a small cobalt addition. What makes it remarkable is how its properties can be tailored through heat treatment. It can be supplied in a softer, more malleable state for easy machining, and then heat-treated to achieve a strength that rivals many steels. This combination of high hardness, excellent wear resistance, and good thermal conductivity is rare in non-ferrous metals, making it a uniquely versatile material.

Beryllium Copper C17000 bars offer excellent strength and hardness at elevated temperatures, maintaining good thermal stability and electrical conductivity. They are highly resistant to oxidation and wear in high-temperature environments.
Yes, Beryllium Copper C17000 bars can be welded, but it requires special care. Preheating, proper filler material, and post-weld heat treatment are essential to prevent cracking and ensure weld strength.
Yes, Beryllium Copper C17000 rods can be customized in size and length to meet specific requirements, allowing for various diameters and lengths based on the application and customer specifications.
The uses for these bars and rods are extensive, particularly in environments where safety and reliability are paramount. They are the preferred choice for non-sparking tools used in oil and gas, mining, and other hazardous atmospheres. You’ll also find them in critical components like heavy-duty springs, valves, and pump parts that must withstand relentless wear and corrosion. Furthermore, their excellent electrical conductivity makes them ideal for intricate connectors and components in the electronics and automotive industries, where precision and durability are essential.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
