Different Types of Nickel Alloys

Different Types of Nickel Alloys

Among metals, nickel is one of the most widely used types. Nickel alloys are compounds of nickel and other metal and non-metal materials. There are a surprisingly large number of nickel alloys, and each has unique properties. Check out this guide on the most common different types of nickel alloys that have everyday applications.

Nickel-Iron Alloys

Nickel-Iron alloys are a combination of nickel and iron metals. The most commonly used nickel-iron alloy is alloy 800. It is mainly composed of nickel, with iron as its next largest material component. It also has a significant amount of chromium, although not nearly as much chromium as iron or nickel. It is known for its medium strength and ability to resist oxidation at high temperatures. One can typically find it in heavy machinery that operates in hot conditions.

Nickel-Copper Alloys

Nickel-Copper alloys are mainly nickel mixed with copper and a small amount of other materials. One of the most common nickel-copper alloys is nickel alloy 400. It contains a minimum of 63 percent nickel, with copper as its second-largest material component. It also contains some iron, along with traces of other metal and non-metal elements. It is a very strong alloy with high corrosion resistance despite extreme temperatures. One can typically find it in chemical and water tanks because of its high resistance to corrosive materials.

Nickel-Chromium Alloys

Nickel-Chromium alloys are 80 percent nickel and 20 percent chromium. These alloys are useful for wrought-iron and cast-iron items, such as a pot that may sit in your kitchen currently. This alloy is extremely heat-resistant and has great oxidation and corrosion resistance in high temperatures. This is a strong metal that is ideal for heat work.

These three different types of nickel alloys are some of the most commonly found nickel alloys that affect people’s day to day lives. Alloys offer more strength and corrosion resistance than pure metals. There are many more types of nickel alloys with a variety of practical applications. These are just three of the thousands that exist.
