A typical next-generation passenger aircraft contains around 250kgs of chromium metal, found in a variety of superalloys according to the application. Engines and exhausts (disks, blades, tailpipes) are the primary uses where their heat, corrosion and creep resistance at very high temperatures (over 1,000°C ) is essential, however they are also found in high-speed parts such as aircraft wheels as well as in heat-resistant bolts, fasteners and casings. Superalloys in the aircraft industry contain around 18-20% chrome metal consumed.

Cr-Ni based superalloys are extensively used in power generation. Whilst their corrosion-resistance means that they continue to play a part in deep-sea drilling environments, they are also at the forefront of clean energy technologies such as nuclear, where their presence in valves and vapour tubes require mechanical resistance to constant high temperature and high pressure. They are also used in gas turbine blades and in turbochargers and be capable of withstanding temperatures of up to 1300°C. Superalloys used in the power generation industry contain between 18-28% Cr content.

Chrome metal therefore is essential in some of the world’s most demanding products and applications and is helping to solve some of the planet’s most pressing environmental concerns. AMG Chrome is a world leader in its production.
