30%W Tungsten Molybdenum Alloy Rod Diameter 30mm
1. Material description of 30%W Tungsten Molybdenum Alloy Rod Diameter 30m:
Tungsten-molybdenum alloy has the common characteristics of tungsten and molybdenum metal, and has good high temperature stability, resistivity and good processing performance under vacuum or inert gas protection.
2. Size of 30%W Tungsten Molybdenum Alloy Rod Diameter 30m:
Diameter 5~150mm
Length <2000mm
Or can process as per customer request.
3. Production method of 30%W Tungsten Molybdenum Alloy Rod Diameter 30m:
Preparation method The molybdenum-tungsten alloy billet production
methods include powder metallurgy, vacuum arc melting and vacuum
electron bombardment melting. The powder metallurgy method is the
most widely used, because the method is simple and can obtain alloy
ingots with fine grains, which is conducive to plastic processing.
The main process of powder metallurgy is: mechanically mixing
molybdenum powder and tungsten powder in proportion; pressing into
original billet by mechanical press or isostatic pressing; then
sintering into alloy billet in a high-temperature sintering furnace
with hydrogen. The sintering temperature increases with the
increase of tungsten content, and its range is between 2150 and
2300 °C. Finally, the sintered billet is rolled or forged into a
product.

5. Temperature characteristics of 30%W Tungsten Molybdenum Alloy Rod Diameter 30m:
Properties (1) The melting point of molybdenum-tungsten alloy
increases with the increase of tungsten content. When the tungsten
content increases to 25%, the melting point of the alloy is about
200℃ higher than that of pure molybdenum. Therefore, the
corresponding alloy composition can be selected in the range of
2620-3410 °C according to the use temperature and the required
melting point of the alloy. This advantage is also one of the
advantages that molybdenum-tungsten alloys are widely used.
So tungsten-molybdenum alloy rods are mostly used as high-temperature components under high temperature conditions.
