DIN 17664 W Nr 2.0882

A German wrought 70/30 Cupro Nickel CuNi30Mn1Fe. The alloy has higher mechanical properties than 90/10 cupro nickel and can withstand greater water flow rates. It has good resistance to bio-fouling and does not suffer from stress corrosion and is ideal in aggressive marine environments. The alloy can also be produced to several other world specifications EN1652/1653/12163/12165/12420 CW354H and Def Stan 02-780 Part 2 and Def Stan 02-879 Part 1 and Part 2, DIN 17670/17672/17675, BS 2870/2872/2874/2875 CN107, ASTM B 122/171/151 C71500, JIS H 3320/3100 C7150, AS 2738-2, NF A 51-115 and GOST 00492 MNZMc30-1-1.
