From the heart of Hamilton, New Zealand, Hemi Metals proudly stands as your trusted source for high-quality copper products. We specialise in supplying premium Copper C10200 Bars and Rods, known for their exceptional purity and reliability. Our local presence ensures you receive not only superior materials but also responsive, personalised service. When your project demands the very best in conductive and ductile copper, you can count on our team to deliver the consistent quality and expert support needed to bring your most important work to life.
Copper C10200, often called Oxygen-Free Electronic (OFE) copper, boasts a minimum purity of 99.95%, making it one of the purest grades available. This high copper content gives it outstanding electrical and thermal conductivity, which is essential for demanding electrical applications. Mechanically, it offers excellent ductility, meaning it can be easily formed and shaped without losing its strength. It’s also highly weldable and possesses a good degree of corrosion resistance, particularly in atmospheric conditions, ensuring longevity in your projects.
