While many suppliers operate on a global scale, Hemi Metals brings a uniquely local focus to quality metal manufacturing. Based right here in Hamilton, New Zealand, we take pride in our hands-on approach to producing and supplying precision materials like our Copper Nickel Bright Bar. Our dedication to local industry means we offer not just a product, but a reliable partnership, ensuring you receive superior-grade materials with the responsive, personalized service that comes from being a neighbour.
This bright bar is crafted from a copper-nickel alloy, often referred to as cupronickel, which typically contains between 10% to 30% nickel. This specific composition gives the material its renowned resistance to corrosion, particularly in harsh marine and industrial environments. The bright drawn finish isn’t just for appearance; it provides a smooth, precise dimension and enhances its surface hardness. The result is a bar that is not only strong and durable but also offers excellent machinability for your fabrication projects.
