Copper-nickel alloys, also known as Cu-Ni alloys, are composed primarily of copper and nickel, with trace amounts of other elements like iron and manganese. These alloys are recognized for their high strength, excellent corrosion resistance, low electrical resistance, and favorable thermoelectric properties. They are especially known for reducing the temperature coefficient of resisti... http://www.alloys-en.com/1-3-cuni-alloy.html
