As you can see from my profile, I have been involved in the sale of chromium metal and the associated consulting and service for over 30 years.

Chromium is a chemical element, with the symbol Cr. Its atomic number is 24; it is the first element in group 6, and has a high melting point. Its melting point is approximately 1900 degrees Celsius. It is steel grey in color and has a glossy surface. Chromium metal has been used industrially for over 200 years. Chromium metal can be produced by means of electrolysis (around 30% of consumption), in which it takes the form of flakes. Its manufacture is naturally very cost-intensive.

However, chromium metal can also be produced aluminothermically. In this process, chromium oxide of metallurgical quality is mixed with aluminum in a crucible and then ignited. The chemical reaction produces so-called chromium corundum (chromium slag) that proportionately contains pure chromium metal.

Chromium metal is produced for sale in forms ranging from pellets to powder. The consumption of pure chromium metal is around 40,000 mt worldwide. Pure chromium metal is used in the aerospace industry, in the production of gas turbines, in medical alloys (implants, dental), in the chemical industry, in the automotive industry, in the steel industry, in foundries, in the coating industry (surface protection, foil coating), in fuel cells, in solar modules, in welding electrodes, and in energy Servers.
