Copper Alloys, Copper-Nickel (Cupro-Nickel)DEFSTAN 02-835 (NES835) Bar & Forgings
An advanced precipitation hardenable copper nickel with improved mechanical properties over 90/10 and 70/30.
DEF STAN 02-835 is a hot forged, stress relieved high strength cupronickel developed primarily for marine and offshore applications. The alloy contains around 14.5% nickel, 4.5% manganese and smaller additions of aluminium and iron to increase the overall material strength and corrosion resistance.
Specified as an MOD (Navy) grade, it combines the inherent corrosion resistance and antibiofouling benefits of traditional cupronickels whilst offering higher strength and toughness levels than the aluminium bronzes.
NES 835 is mainly used in naval engineering, aerospace and defence applications.
