UDT 2019: Copper Alloys releases submarine seawater systems material
A new material intended for submarine seawater systems, Def Stan 02-886 has been released by Copper Alloys Ltd.
Made out of a copper-nickel-chrome alloy, it has been used for the systems of various vessels in the UK Royal Navy, and is now available in wrought form.
Designed to replace nickel-aluminium-bronze, it took 30 years of development alongside the MoD. Def Stan 02-886 is produced with similar processes to those used to create cupro-nickels, nickel-aluminium-bronze and nickel alloy forgings.
The material underwent a number of tests before its release in February. An independent testing facility carried out 60 destructive mechanical tests, finding Def Stan 02-886 to be five times more resistant to shock than nickel-aluminium-bronze.
Seawater fatigue tests carried out by the governments of Australia and the UK found that forging copper-nickel-chromium increased its mechanical properties and ability to resist corrosion.
Costing exercises were also carried out, showing that components made from Def Stan 02-886 equated to about the same as those made from nickel-aluminium-bronze. The material would also last the lifetime of the ship or submarine that it was applied to, whilst a nickel-aluminium-bronze equivalent would require replacing up to five- times over the lifetime of a vessel.
