Hiduron 191 NES 835

Hiduron 191 NES 835 is a strong cupronickel alloy with elements of roughly 14.5% nickel and 4.5% manganese which is strengthened by additions of iron and aluminium. Hiduron 191 offers high strength along with higher anti-fouling characteristics and similar marine corrosion resistance to regular cupronickels, as well as higher toughness and tensile properties when compared to aluminium bronzes.

Hiduron 191 can be hot forged, has good weldability & machinability and can be thread rolled without difficulty.
