Analysis of tungsten molybdenum alloy cube
In addition to tungsten copper alloy and tungsten silver alloy, there are tungsten molybdenum alloy. According to the different design shape, W-Mo alloy can be divided into cuboid, cube (cube), hexagonal, cylindrical and spherical, they have the same physical and chemical properties in the same raw material ratio, production process and process parameters under the same conditions, but different uses.
Take the tungsten molybdenum alloy cube as an example. It is a kind of alloy material composed of refractory metal tungsten and molybdenum, which is called Tungsten Molybdenum Cube in English. The tungsten content in common tungsten-molybdenum alloys is 30% ~ 50%. Note: Tungsten-molybdenum alloys can also be called tungsten-molybdenum alloys when the molybdenum content is greater than the tungsten content.
In terms of physical and chemical properties, W-Mo alloy cube has the characteristics of high melting point (2620 ~ 3410℃), high density, high strength, high hardness, low thermal expansion coefficient, low vapor pressure, good electrical conductivity, thermal conductivity and wear resistance, etc. Note: the properties of the alloy will be different with the ratio of raw materials, mainly reflected in the melting point, hardness and strength of the alloy will basically improve with the increase of tungsten content.
In terms of production process, W-Mo alloy cube can be produced by powder metallurgy, vacuum arc melting, vacuum electron bombardment melting and 3D printing technology. Among them, the steps of powder metallurgy technology: the tungsten powder and molybdenum powder are mixed first, and then pressed into the blank by mechanical press, and finally sintered in high temperature sintering furnace to get the required products. Steps of 3D printing technology: tungsten powder and molybdenum powder are mixed first, and then spray granulation technology is used to prepare the mixed powder into spherical precursor powder, and finally sintering, spherodizing treatment can be done.
From the point of use, the tungsten molybdenum alloy cube can not only be used as paperweight and a variety of mechanical equipment, but also as a souvenir.
