B10(BFe10-1-1, C70600, CuNi10Fe1Mn) iron white copper is a copper-nickel-based quaternary alloy with a small amount of iron and manganese. The addition of elements Fe and Mn significantly enhances the mechanical properties and corrosion resistance of the alloy. Alloys possess excellent comprehensive mechanical properties and corrosion resistance, and are widely used in condensers, heat exchangers, etc.
