Aluminum-nickel alloy is widely used in the production of hydrogen through the catalytic reforming of hydrocarbons. It serves as an effective catalyst in processes like steam reforming, where it helps convert methane and other hydrocarbons into hydrogen and carbon monoxide. This application is crucial in industries such as petrochemicals and energy, where hydrogen is a key component for refining and fuel production.

Additionally, the alloy is employed in the manufacturing of high-performance magnets, particularly in the creation of Alnico magnets. These magnets are known for their strong magnetic properties and resistance to demagnetization, making them suitable for use in electric motors, sensors, and various industrial equipment.

In the aerospace sector, aluminum-nickel alloy is utilized for its lightweight and durable characteristics. It is often incorporated into components that require a balance of strength and weight efficiency, such as turbine blades and structural parts in aircraft.

Furthermore, the alloy finds application in the field of metallurgy as a deoxidizing agent in steel production. It helps remove oxygen from molten steel, improving the quality and strength of the final product. This makes it valuable in the construction and automotive industries, where high-strength steel is essential.
