Applications of Ni Alloys

‘Nickel mixtures are indispensable across numerous industries, with their applications spanning aerospace, automotive, and chemical processing sectors.’. In aerospace, these materials are essential for parts such as turbine engines and exhaust systems, valued for their high-temperature strength and durability against oxidation. ‘The automotive sector gains advantages from metal mixtures in components that require strength and toughness in severe conditions, such as exhaust systems.’. Chemical processing industries utilize certain alloys for their exceptional resistance to corrosive media, making them ideal for use in valves, pumps, and heat exchangers.

The demand for this metal is projected to surge by around 65 percent by the end of the decade, driven largely by the energy transition. Nickel’s role in energy storage technologies, particularly in the cathodes of lithium-ion batteries for electric vehicles (EVs), is expanding. At present, only four percent of the world’s metal output is utilized in vehicle batteries, but this figure could increase to 40 percent by 2030. This increased usage is not limited to EVs; wind turbines, solar panels, and green hydrogen production also require high-performance metal alloys.

The aerospace sector’s rebound and increasing need for jet aircraft from firms such as Boeing and Airbus are anticipated to drive metal prices higher. This could potentially strain the supply for energy infrastructure projects, which also rely on nickel for various equipment. The global leader in motion and control technologies, Parker, continues to play a vital role in developing precision-engineered solutions that rely on these high-performance materials, contributing to a cleaner, smarter, and safer world.

Corrosion Resistance of Ni Alloys

‘Nickel mixtures are famous for their outstanding ability to withstand corrosion, a trait that is vital for numerous industrial uses.’. This opposition is primarily caused by the creation of a protective oxide layer on the metal’s surface when subjected to corrosive conditions. In particular, nickel-copper and nickel-molybdenum mixtures excel in resisting pitting and crevice corrosion, making them indispensable in marine and chemical industries.

The practical advantages of this corrosion protection are significant. For instance, the robust performance of these alloys in harsh conditions can extend the lifespan of components used in offshore wind farms. The International Energy Agency projects a fifteen-fold increase in global offshore wind capacity by 2040, highlighting the importance of durable materials.

Furthermore, this barrier lowers maintenance expenses significantly. Given the high capital expenditure required for constructing and operating offshore installations, minimizing maintenance through the use of corrosion-resistant materials is economically advantageous. As Dr. Kaiping Yu noted, understanding and exploiting corrosion resistance mechanisms can lead to breakthroughs that enhance material performance and reliability.

Researchers at Pacific Northwest National Laboratory (PNNL) have also developed new techniques to monitor corrosion more accurately. Traditional methods often left gaps in understanding corrosion progression, but advanced techniques like Shear Assisted Processing and Extrusion (Shape™) provide high-resolution insights. This improved comprehension aids in the creation of metal mixtures that can endure even the most challenging settings, guaranteeing both durability and cost-effectiveness.
