Welcome to Hemi Metals, your trusted manufacturing partner in Hamilton, New Zealand. We specialize in providing high-performance Beryllium Chromium Copper bars and rods, crafted with precision to meet the most demanding industrial challenges. Sourced and processed with care, our materials are the go-to choice for engineers and fabricators across the country who require reliability and superior quality from a local supplier they can count on.
The unique composition of this alloy, primarily copper with small but critical additions of beryllium and chromium, gives it an exceptional blend of qualities. It offers high strength and hardness, comparable to many steels, alongside the excellent thermal and electrical conductivity you expect from copper. This means components can handle significant mechanical stress while efficiently managing heat, making it a truly versatile material for critical applications.
