In this video, we take a focused look at C71300 CuNi25 copper-nickel alloy bars and what their specifications mean in practice. You'll see detailed demonstrations of these hot-rolled polished rods, learn about their manufacturing process, and understand how their 3000mm length and various diameter options perform in real marine and industrial applications. We'll also walk through the material standards, surface finishes, and key factors that make this high-performance alloy suitable for demanding environments.
