Aung Metals, located in Naypyidaw, Myanmar, has built a solid reputation as a top-notch manufacturer and supplier of high-quality Copper C11400 Bars and Rods. With a strong focus on quality, innovation, and precision, Aung Metals delivers copper products that adhere to international standards for various applications, including electrical, mechanical, and industrial uses. Known as Tellurium Copper, Copper C11400 boasts impressive electrical conductivity along with excellent machinability and resistance to corrosion. Thanks to advanced production methods and strict quality control, Aung Metals guarantees that each bar and rod performs consistently, making them a reliable partner for clients in the electrical, automotive, and engineering sectors.
The Copper C11400 Bars and Rods are primarily made of high-purity copper (around 99%) with a small amount of tellurium (0.4–0.7%) added to improve machinability. This alloy maintains about 90% of the electrical conductivity of pure copper while significantly enhancing wear resistance and cutting performance. It features a tensile strength of roughly 250–350 MPa, a yield strength of about 50–150 MPa, and outstanding ductility. Its unique blend of electrical conductivity, strength, and ease of machining makes it perfect for precision manufacturing and high-performance applications.

Copper C11400 Bars and Rods have good thermal conductivity but are not ideal for high-temperature applications. They are best used at temperatures up to 200°C to prevent softening and degradation.
Yes, Copper C11400 Bars and Rods are fully recyclable. The material retains its properties after recycling, making it an eco-friendly option for sustainable industrial use and reducing environmental impact.
Copper C11400 Bars and Rods are naturally resistant to corrosion in many environments. However, in harsh conditions such as marine or acidic environments, additional protective coatings may be recommended.
Copper C11400 Bars and Rods find extensive use in industries that demand both high conductivity and superior machinability. They are particularly well-suited for creating electrical connectors, switchgear components, terminals, transformer parts, and welding tips. The alloy’s excellent resistance to corrosion also makes it a great choice for plumbing, refrigeration, and mechanical parts that come into contact with moisture and chemicals. Additionally, due to its strength and ease of workability, Copper C11400 is frequently used in the production of fasteners, hardware components, and machined electrical fittings for automotive, marine, and industrial systems.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
