Description

DEF STAN 02-835 Copper Alloy 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. It shows the following features and properties:

High strength

Excellent corrosion and biofouling resistance

High impact strength retained down to cryogenic temperatures

Spark resistance
