Description: Stoker Concast provides two groups of copper-nickel alloys in the 90/10 and 70/30 ranges both having corrosion resistance in sea water. The corrosion resistance could be much improved by adding iron and maganese. In this form, these are particularly useful for seawater condenser systems and for cladding off-shore structures. We also offer another group of alloy that are used for electrical connectors and springs.
