Nickel alloys, also known as high-performance alloys, are metals that contain some nickel in their elemental makeup to improve some of their properties and make them better suited for applications outside their typical wheelhouse. Letâs look at everything to do with nickel alloys, including where theyâre used, the different types, and their characteristics and physical properties.
THE ISO designation system for indexable insertsThe ISO designation system for indexable inserts (ISO 1832) is a standardized system to name an indexable insert.The system is designed so that each important feature and dimension of the insert is shown using a code system. This becomes the name of the insert. This system has several advantages:Unique naming of an indexable insert (supplier independent)All important features and dimensions are clearly stated in the nameSome code positions relate to the insert carrier in which the insert can be mounted It's important to remember that the ISO designation system is not a system that standardizes the quality of the insert. Neither the carbide grade nor the cutting geometry is standardized in this designation system. This is an example for milling inserts.

Nickel alloys are typically reserved for high-performance applications because they tend to be more expensive than other types of metal. As weâve seen, nickel alloys are usually strong and tough, and that can make them a pain to machine. If youâre interested in machining this type of alloy, youâll probably need extra tools.

Their high melting points can make them difficult to weld, but itâs not impossible. If you want to create a sufficient pool of weld metal, youâll need more heat, but if you use more heat, thereâs more chance of residual stress which can deform the component. Basically, it needs a lot of care. When in long-term contact with the skin, some nickel alloys can cause an allergic reaction. Thatâs why theyâre probably not the best choice for wearables and medical devices. Also, when exposed to the elements, some nickel alloys (especially copper-based) will tarnish over time.
The system is designed so that each important feature and dimension of the insert is shown using a code system. This becomes the name of the insert.
If a metal contains nickel as one of its primary elements, itâs classified as a nickel alloy. Some types of nickel alloys are even classed as âsuperalloysâ 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. Hereâs an image of a nickel alloy in use:

Itâs believed that the first nickel alloy was used in 200 BCE in China. Thatâs the earliest record available, and the material was referred to as âwhite copper,â which experts believe was an alloy of nickel and silver. Fast forward to 1751, A. F. Cronstedt, a German scientist, managed to isolate nickel from the niccolite mineral. Copper and zinc were often found in these first nickel alloys, which came to be known as âGerman silverâ and werenât really used for anything other than ornaments.
After James Riley made an iron-chromium alloy in 1913, W. H. Hatfield figured out that adding nickel to these alloys would make them incredibly corrosion-resistant. This led to the creation of what we now know as austenitic stainless steel.

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, youâd 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 thatâs 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.

Itâs generally quite hard to differentiate nickel alloys from other types of metals. Nickel alloys can seem slightly dull when their surface is rough, but when itâs smooth, they can be shiny and reflective. Hereâs an example of what copper-nickel alloy rods look like:
