| Application areas | Thanks to its very high corrosion resistance against many different acids and bases as well as hot gases, chromium is a popular material for all types of protective coating. In combustion equipment, chromium is used as a wear-resistant coating to increase the service life of specific components. As a component in high-temperature fuel cells, chromium also performs brilliantly. Alongside these applications, chromium is also used as a brilliant decorative coating for operating elements on appliances or for jewellery. | |
