From the heart of Hamilton, New Zealand, Hemi Metals proudly manufactures and supplies high-performance materials for demanding industries worldwide. Our commitment to precision and reliability is perfectly embodied in our range of Copper Nickel Hex Bars. We understand that the integrity of your components starts with superior raw materials, which is why we provide hex bars that offer exceptional resistance to corrosion and strength, supporting local engineering and international projects with the same unwavering quality and dedication.
The composition of our Copper Nickel hex bars, typically a 90/10 or 70/30 copper-nickel blend, is enhanced with small additions of iron and manganese. This specific alloying creates a material with outstanding mechanical properties. These bars are known for their remarkable tensile strength and excellent ductility, allowing them to be machined into complex parts with ease. Most importantly, they possess a proven resistance to corrosion, particularly in aggressive marine and chemical environments, ensuring long-lasting performance.
