COPPER-NICKEL ALLOYS
Copper-Nickel alloys are recognized primarily for their ability to withstand seawater corrosion, erosion and biofouling and therefore are widely used in marine and offshore industries.
C70600 - (90-10) Copper-Nickel is widely used in marine applications where resistance to both corrosion and biofouling is important.
C71500 - (70-30) Copper-Nickel is preferred to 90-10 Copper-Nickel where corrosion and temperature conditions are more severe.
COPPER-NICKEL TEMPERS
060 - Soft (Sheet/Rod)
061 - Annealed (Tube)
H01 - Hard (Sheet/Rod)
M20 - Soft (Plate)
M20 - Hard (Plate)
Features:
High tensile strength
Resistance to biofouling
Corrosion resistance
Easy installation
