ABSTRACT:
New nickel alloys are described which are useful for eyeglass frames, which alloys in addition to good resistance to corrosion also have good workability properties. They contain 5 to 20 percent copper and 5 to 30 percent zinc. Optionally, they can also be alloyed in small amounts other metals such as manganese, silicon, beryllium, cobalt, aluminum, niobium, tantalum, or titanium.
