Nickel based alloys are chosen because of the corrosion resistance, heat resistance/high and low temperature properties.
Applications for nickel alloys
Nickel alloys are used in a variety of industries, such as: aircraft gas turbines, steam turbine power plants, nuclear power systems and the chemical- and petrochemical industries. Overall, nickel alloys offer a combination of strength, corrosion resistance, heat resistance, and versatility that makes them valuable in demanding industrial applications. Their properties make them suitable for environments where other materials may fail, allowing for improved performance, durability, and reliability.

Nickel alloys are a group of metallic materials that contain a significant amount of nickel as their primary alloying element, typically combined with other elements such as chromium, iron, copper, molybdenum, and others. These alloys exhibit unique properties that make them useful in a wide range of applications across various industries. Below we collected some key points about nickel alloys:
High Strength and Corrosion Resistance: Nickel alloys are known for their excellent combination of high strength and corrosion resistance. They can withstand harsh environments, including high temperatures, extreme pressures, and corrosive substances.
Versatile Applications: Nickel alloys find applications in diverse industries, including aerospace, chemical processing, oil and gas, power generation, marine engineering, and electronics. They are used in components such as turbine blades, valves, heat exchangers, chemical reactors, and electrical resistance wires.
Heat Resistance: Nickel alloys possess excellent heat resistance, making them suitable for high-temperature environments. They maintain their strength and structural integrity at elevated temperatures, making them ideal for applications such as gas turbines.
Corrosion Resistance: Nickel alloys have exceptional resistance to corrosion, particularly in harsh environments where other materials might fail. They resist attack from acids, alkalis, seawater, and various corrosive gases, making them valuable in chemical processing, marine, and offshore applications.
Magnetic Properties: Nickel alloys can exhibit ferromagnetic or paramagnetic properties depending on their composition and processing.
Weldability and Fabrication: Nickel alloys can be welded, allowing for the fabrication of complex structures and components. However, they require specialized welding techniques and proper heat treatment to maintain their desired properties.
Cost: Nickel alloys tend to be more expensive than common steels due to the higher cost of nickel and the complexity of their production. However, their unique properties often justify their use in critical applications where their performance outweighs the cost considerations.
