The development of wrought copper nickel chrome is in no small part down to the work of Ben Turner. For the last 15 years he has made it his ambition to help Navies keep submarines in the water and save the taxpayer money. His work with the British Corrosion Institute shows you the truth about material performance. The groundbreaking wrought CNC to Def Stan 02-886 is proven to be the most corrosion resistant copper based alloy around.
