From the heart of Hamilton, New Zealand, Hemi Metals proudly crafts and supplies premium Copper C10300 Bars and Rods, bringing exceptional quality right to your doorstep. We understand that dependable materials are the foundation of any successful project, which is why our commitment to precision and local service ensures you receive a product you can trust. Whether you’re a local engineer or an international partner, we provide the reliable, high-performing copper you need to build with confidence.
C10300 is essentially pure copper, known for its excellent electrical and thermal conductivity, which is second only to silver. This high purity also gives it outstanding ductility and formability, allowing it to be easily shaped and fabricated. While it’s known more for its conductive properties than sheer strength, it offers good corrosion resistance, making it a wonderfully versatile and manageable material for a wide range of applications where efficient energy transfer is the top priority.
