NES 835 is an aluminium bronze that has a great strength combined with excellent sea water corrosion and erosion resistance so is used a lot in the marine industry. Also NES835 has been one of the only materials to consistently show no effects of hydrogen embrittlement and also has good stress corrosion cracking with additions of iron in ammonia but the iron content has to be below 1% and the iron has to be retained in the solution.
