molybdenum Stab
With a melting point of around 2600 ° C, molybdenum is a
slightly lower melting metal than tungsten. However, its properties are
very similar. The sintered material is practically not cold-formable and
brittle at normal temperature.
At temperatures between 1000 and 1600 ° C, the semi-finished products
are given their basic shape by forging, round hammers, rollers or
extrusion. Subsequent grinding of the surface enables workpieces with
very tight tolerances to be produced.
Molybdenum is resistant to most acids, alkalis and non-metals.
(Prerequisite: air humidity <60%; the respective application must be
considered separately). Molybdenum is not stable in oxygen-releasing and
in alkaline liquids at temperatures above 100 ° C. Molybdenum is very
resistant to hydrogen, nitrogen, noble gases, glass and molten metals -
even at very high temperatures. Alloying with other high-melting metals
can further improve the corrosion behavior towards certain media.
Compared to tungsten, molybdenum is easily deformable and easier to
process even at low temperatures. The brittle-ductile temperature during
forming must be taken into account - the thicker the material, the
higher the heating temperature. Above the brittle-ductile temperature,
molybdenum loses its brittleness - it can be reliably deformed without
cracks. Cutting, punching and machining are also possible with the
correct heating temperature.
