Properties vary with composition, however, some properties are outlined below.
Copper 90/10 and Copper 70/30
• Outstanding resistance to corrosion, particularly sea water
• 70/30 is stronger and has superior resistance to impingement corrosion
• Good resistance to biofouling, with the 90/10 alloy being slightly superior compared to the 70/30 alloy
Copper rich alloys are:
• Can be hardened only by cold working
• Good corrosion resistance
• Good strength
• Low temperature co-efficient of electrical resistance
The nickel content in these alloys also enables them to retain their strength at elevated temperatures compared to copper alloys without nickel.
