I have acquired about ten or twelve pounds of cupronickel from a marine application and am wondering what it might be worth to a scrapyard. Also, is there any way to determine the ballpark nickle content as it would certainly affect value. Thanks.

Try to go to a Larger Yard that has a Handheld Analyzer , that will give a correct percentage of each metal in your C.U.N..

Actually there are several elements that are (can be) added to Cu-Ni, it just depends on what the intended use of the ally is. Some of the more common elements you might find in Cu-Ni include: manganese, iron, tin, niobium, silicon, chromium, beryllium and aluminum, titanium, zinc (1% maximum). There are others but these are the most common.

Nickel has a marked effect on the color of Cu-Ni alloys. The copper color becomes lighter as nickel is added. Alloys are almost silvery white from about 15% nickel. The lustre and purity of the color increases with nickel content. From about 40% nickel, a polished Cu-Ni surface can hardly be distinguished from that of silver.

Cu-Ni alloys are corrosion resistant copper alloys. They are resistant to moisture, non-oxidizing acids, alkalis, salt solutions, organic acids and to gases such as oxygen, chlorine, hydrogen chloride, hydrogen fluoride, sulfur dioxide and carbon dioxide.
