Cu-Ni alloy 90/10 offers superior resistance to general corrosion and marine water attacks. It resists corrosion by fast moving water. It has nominal temperature coefficient of electric resistance. Alloy 90/10 prevents stress corrosion cracking and pitting and crevice corrosion. The resistance to soil erosion and abrasive fluids is incomparable in the aqueous conditions. It is commonly employed in seawater hardware, condenser tubes, automotive cooling systems and in manufacturing coin.
