Defence Releases
Copper Nickel to Naval Standards
DEF STAN released engineering raw materials governed by defence standards through the British Ministry of Defence (MOD).
While the material releases offer much of the same as equivalent alloy grades, DEF STAN-specified materials tend to be produced to more stringent standards with tighter chemistry and mechanical properties controls. In some instances, there are mandatory performance requirements, such as impact resistance.
Naval Grade Material
DEF STAN material is often referred to as 'naval grades' since these alloys were released originally for use with the Royal Navy and continue to be supplied today. However, like many copper-nickel alloys, DEF STAN released alloys are exclusively sold to a single market.
Broader Appeal
DEF STAN material has benefitted from much broader appeal, finding use in commercial engineering applications throughout the marine, petrochemical and oil & gas sectors.

Biofouling Performance
Biofouling is a significant issue in the marine sector, where the build-up of microorganisms may damage or impair performance.
Plants, algae and even small animals can degrade pipework, structures, inlets and hulls, leading to failure or costly maintenance.
We stock DEF STAN grades, which offer effective resistance to the issue of biological fouling.
Stock Portfolio
DEF STAN is a British Defence Standard created by the Ministry of Defence (MOD) and we stock copper nickel material to these specifications.
We stock DEF STAN copper nickel alloys in solid round bars, which we also process in-house to your size requirements.
We supply products in various specifications and in much closer incremental sizes, resulting in engineering materials which are nearer to your finished size requirements.
