Chromium Tube Description
Chromium is a type of light metal with a blue silvery-white colour. It is reflective, hard and brittle and exhibits high corrosion resistance and a high melting point. Chromium is distinguished by its magnetic properties; it is the only elemental solid that exhibits antiferromagnetic ordering at room temperature (and below).

Applications of Chromium Tubes
Due to its high corrosion resistance, chromium metal is frequently employed for various protective coatings. Given its high resistance to hot gases, it is used as a component in high-temperature fuel cells. In addition, chromium is utilised in combustion systems as a wear-resistant coating to extend the lifespan of specific components.
Chromium metal is also applied as a decorative coating for control elements of devices or for jewellery.
Packaging of Chromium Tubes
Our chromium metal products are clearly marked and labelled externally to facilitate efficient identification and quality control. Care is taken to ensure that no damage occurs during storage or transport.
