Based in the heart of Hamilton, Hemi Metals is a trusted local source for high-quality copper products, including our popular C11400 bar and rod stock. We understand that reliable materials are the foundation of any successful project, which is why we pride ourselves on supplying consistent, high-purity copper that our customers in manufacturing and engineering can depend on. When you need durable and conductive copper delivered with the service you expect from a New Zealand-owned business, we are here to provide the right materials and support for your specific application.
The C11400 alloy is essentially electrolytic tough pitch copper, known for its excellent balance of properties. It boasts a very high copper content, typically over 99.90%, with just a small amount of oxygen. This composition gives it outstanding electrical and thermal conductivity. Mechanically, it offers good strength and excellent ductility, allowing it to be easily formed, machined, and soldered. This combination makes it a versatile and reliable choice for a wide range of demanding technical applications where performance is critical.

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.
This specific grade of copper bar and rod is incredibly versatile, finding its way into numerous essential industries. It’s the go-to material for electrical components like busbars, connectors, and switchgear due to its superior conductivity. You’ll also find it in plumbing systems for valves and fittings, as well as in heat exchangers and various architectural applications. Its excellent workability makes it a favourite among fabricators and engineers who need a material that is both highly functional and easy to work with for creating precisely crafted parts.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
