The Benefits of using Molybdenum Machined Parts or Fabricated Products

The Benefits of Using Molybdenum

 One of the great things about using molybdenum for machined parts or fabricated products is that it is so versatile. It can be used in a wide variety of applications thanks to the fact that, when it is a pure element, molybdenum is very hard. Furthermore, the metal offers an extremely high melting point which can exceed 2,500 °C, when relatively pure. In addition, it possesses a high thermal conductivity and affords high levels of corrosion resistance to both glass and other metals. Let’s take a look at these properties in a bit more detail and establish just how they can be advantageous within a number of industrial applications.

 The Hardness of Molybdenum

 Products which are exposed to grinding motions and friction are ideal for being made from molybdenum, due to its exceptional hardness. This means that it is not liable to be deformed or that components will wear down rapidly, potentially making them unsafe to use in an environment where they cannot be inspected regularly. As such, molybdenum is often used for medical parts or stirring equipment thanks to its ability to remain hard. It is also much favoured by sections of the aerospace industry for the same reason. The silvery metal has a hardness level of 5.5 when measured in Mohs. It is frequently used with other metals to improve the hardness of a specific alloy, particularly when stiffness is property that is desirable, such as is found in high strength steel alloy.

The Melting Point of Molybdenum

 Molybdenum is an outstanding material that can frequently deal with the toughest requirements of components that will be put to use in high temperature situations. Because the metallic element has a very high melting point as well as a low thermal expansion co-efficient, precision parts can be fabricated from it that will not deform under heat. It can be used to provide parts such as glass melting electrodes and used in the extremely hot conditions of furnaces. It is also much utilised in highly pressurised environments where other metals would be liable to melting, such as with certain pigmentations and catalysts. Of great benefit to those who use it in high temperature applications, pure molybdenum has a melting point of about 2620 °C.

 The Thermal Conductivity of Molybdenum

 Because it conducts heat very efficiently, molybdenum is able to be used for things like sputtering targets which are often used for coating solar cells and flat screens, among other things. It can also be used to produce wiring for the lighting industry where heat generated from lamps can cause other metals problems. The thermal conductivity of molybdenum is measured at 138 W/(m·K) which means that it is frequently a chosen material for the electrical component industry. High power densities and electrical flow through some transistors, for example, can produce plenty of heat. The same is true of certain power diodes, but those made from molybdenum can conduct this heat with ease.

The Corrosion Resistive Properties of Molybdenum

 The glass manufacturing industry has long used molybdenum for its stirrers which mix together all manner of glass melt. Of course heat resistance is important for this, but the corrosion resistance of molybdenum against both metal and glass melts is also crucial for it to be the material of choice in the industry, allowing for the long life of components. Where corrosive materials are mixed, such as free sulphur which can behave like a oxidiser, molybdenum alloys are often put to use. Chrome and molybdenum are frequently used together in an alloy form by the automotive industry and for earth moving equipment because it is so corrosion resistant, too.
