Molybdenum (Mo)

A tongue-twister but nevertheless valuable beyond words! We supply molybdenum at a purity of more than 99.8%. Like tungsten, molybdenum is a high melting-point refractive metal with outstanding thermo-physical, mechanical, and chemical properties.
Molybdenum is resistant to most acids, alkaline solutions, and non-metals. At temperatures above 100 °C, molybdenum is unstable in oxidizing and alkaline fluids. It is highly stable against hydrogen, nitrogen, inert gases, glass, and metal melts – even at very high temperatures. By alloying with other high melting-point metals, the corrosion resistance to certain media can be increased even further. Compared to tungsten, molybdenum can already be shaped and easily machined at low temperatures.
The brittle-ductile temperature during forming must be observed – the thicker the material, the higher the heating temperature. Above the brittle-ductile temperature, molybdenum loses its brittleness – it can be reliably formed without cracks. Cutting, stamping and machining are also possible at the correct heating temperature. Through targeted and precisely controlled alloying measures, we achieve molybdenum alloys with further optimized properties – precisely tailored to the highest requirements in the high-tech sector. For example: Molybdenum-Lanthanum (ML), Titanium-Zirconium-Molybdenum (TZM), Molybdenum-Copper (MoCu), Molybdenum-Tungsten (MoW) etc.
