WebMolybdenum has a very high melting point so it is produced and sold as a grey powder. Many molybdenum items are formed by compressing the powder at a very high pressure. Most molybdenum is used to make alloys. It is used in steel alloys to increase strength, hardness, electrical conductivity and resistance to corrosion and wear. WebMolybdenum works in tandem with iron to support several essential biological processes. Iron is a well-known mineral that plays a critical role in the production of red blood cells and the transportation of oxygen throughout our body. Molybdenum enhances iron’s effectiveness by aiding in its absorption and utilization.
