Nickel alloys are alloys that predominantly consists of nickel, among other material. These alloys are known for their excellent corrosion resistance, high-temperature strength, and various other desirable properties. Here are some common types of alloy that consist of nickel:

Monel: Monel alloys typically consist of about 65-70% nickel, along with copper and small amounts of iron, manganese, and other elements. They exhibit exceptional resistance to corrosion and high mechanical strength. Monel is commonly used in marine applications, chemical processing, and oil and gas industries.

Inconel: Inconel alloys are primarily composed of nickel, chromium, and small amounts of iron, with other elements added to enhance specific properties. They offer excellent oxidation and corrosion resistance at high temperatures. Inconel alloys are widely used in aerospace, gas turbine engines, and chemical processing applications.

Hastelloy: Hastelloy alloys are a group of nickel-molybdenum-chromium alloys with excellent resistance to corrosion, particularly in highly corrosive environments. They can withstand extreme temperatures and are commonly used in chemical processing, pollution control, and nuclear industries.

Nimonic: Nimonic alloys are nickel-chromium-based alloys that also contain small amounts of titanium and aluminum. They possess high-temperature strength, excellent corrosion resistance, and good oxidation resistance. Nimonic alloys find applications in gas turbine components, aerospace, and heat-treating industries.

Copper Nickel alloys: Copper Nickel alloy, also known as cupronickel alloys, combine nickel with copper in various proportions. Copper Nickel alloy offers good resistance to corrosion and are commonly used in marine applications, such as shipbuilding, heat exchangers, and desalination plants.

Nickel-chromium alloys: Nickel-chromium alloys, also called Nichrome, are known for their high-temperature strength and resistance to oxidation and corrosion. They are widely used in heating elements, electrical resistors, and industrial furnaces.

Nickel-titanium alloys: Nitinol alloys exhibit shape memory and superelastic properties. They are primarily composed of nickel and titanium and are utilized in various applications, including medical devices, aerospace, and robotics.

These are just a few examples of the many types of nickel alloy available, each with its own unique composition and properties tailored for specific applications.

Nickel alloy find a wide range of applications across various industries due to their unique combination of properties. Nickel uses are vast. Here are some industrial applications of nickel-based alloys:
