NES834 / DEF STAN 02-834 / DGS1044

 

Defence Standard 02-834 / NES834 is an aluminium silicon bronze that offers similar properties to other aluminium bronzes including good strength levels and a high corrosion resistance. However, it is primarily recognised and specified by the MoD (Navy) for its controlled low magnetic permeability level of <1.005.

With an aluminium content of ~6% and a ~2% silicon addition the material gives designers a very good impact strength that is maintained down to cryogenic temperatures. The Defence Standard 02-834 also offers a superior machinability rating to other aluminium bronzes providing designers with a superb combination of properties and more options during the material selection process.
