If a metal contains nickel as one of its primary elements, it’s classified as a nickel alloy. Some types of nickel alloys are even classed as “superalloys” because, if you compare them to other metals, their oxidation and creep resistance is off the charts and allows them to be used at temperatures of over half their melting points. Although not all superalloys are nickel alloys, the vast majority of them are nickel-based.
Not all metals can be mixed with nickel, but some of the most common elements are iron, chromium, aluminum, molybdenum, copper, cobalt, and titanium. To make nickel alloys, you’d have to follow the same process used for pretty much every other metal alloy. The alloying elements need to be decided on, and their ratios need to be carefully chosen. Once that’s done, the elements are all melted together in something like an arc furnace, which also purifies them, and then the alloy is cast into ingots, and off to be formed using either cold or hot processing.
