CUN25ZN18 is a German standard diamagnetic zinc cupronickel, which is equivalent to BZN25-18 in China

Cupronickel is a copper-based alloy with nickel as the main added element, which is silvery-white and has a metallic luster, hence the name cupronickel. Copper and nickel can be infinitely solid solution with each other, thus forming a continuous solid solution, that is, regardless of the proportion of each other, it is always a single-phase alloy. When the nickel is melted into the red copper D200, the content is more than 16, the alloy color becomes relatively white as silver, the higher the nickel content, the whiter the color, but, after all, fused with copper, as long as the nickel content ratio does not exceed 70, the naked eye will see the yellow color of copper.

What's more, the nickel content in cupronickel is generally 25
