Nickel aluminum alloy, often used as a precursor for Raney nickel, is widely employed as a catalyst in various chemical reactions, particularly in hydrogenation processes. It is effective in converting unsaturated compounds into saturated ones, making it valuable in the production of fine chemicals and pharmaceuticals. In materials science, nickel aluminum is utilized in the creation of intermetallic compounds like NiAl and Ni₃Al, which are known for their high strength, lightweight properties, and resistance to oxidation at elevated temperatures. This makes it suitable for use in aerospace and automotive industries, where durable and heat-resistant materials are essential. Furthermore, nickel-aluminum alloys contribute to the production of nickel-metal hydride (NiMH) batteries, which are commonly used in portable electronics and hybrid vehicles due to their high energy density and long cycle life.
