If you’ve never heard of Molybdenum alloys, you have much to learn. This alloy is valuable in a variety of ways due to its outstanding ability to resist corrosion, which is at a level close to that of Tungsten. There are three types of Molybdenum alloys, which offer different capabilities according to their specific combination of elements. The three alloys are: TZM Molybdenum – 99% MO, 0.5% Ti, .0.08 ZR; Molybdenum / 30% Tungsten; and Molybdenum / 50% Rhenium.
The Molybdenum family of alloys offers many valuable attributes which make them great for use in various industrial applications. These include the alloy’s low vapor pressure, electrical resistivity, a low emission level, ductility, resistance to corrosion, great machinability, low level of thermal expansion, easy fabrication capability, excellent thermal conductivity, and a high level of strength and stiffness even at high temperatures. These qualities have made Molybdenum alloys great for use in creating heat shields, nozzles for rockets, tools, filaments, jet tabs, and more.
Molybdenum alloys are machined in different ways depending on how the alloy has been processed. Pressed Molybdenum alloys machine in a way that is similar to how medium hard cast iron is. Molybdenum alloys that have been wrought machine in a way that is similar to how stainless steel is worked. Unlike cast iron or steel, however, Molybdenum can break at the edges if dull cutting tools are used. Molybdenum is also a very abrasive metal, which means that it can wear out tools faster than steel can.
These alloys have a corrosion resistance level that is close to that of Tungsten, and they are great for resisting non-oxidizing mineral acids. Molybdenum alloys also offer a high level of resistance to corrosion from other elements, including chlorine and iodine vapors.
Another quality of Molybdenum alloys is their ability to bend and shape after being heated. Sheets of these alloys can be formed into many complicated shapes after heating, and they can also be sawed easily.
This also explains why Molybdenum is used the majority of ultra-high strength steels, such as those destined for use in highly stressful applications such automotive bumpers and a building structural components due to its ability to increase other metals tensile strength and flexibility. By simply adding amounts varying from 0.25 to 8% of Molybdenum helps to increase the materials minimum yield point up to 300,000 psi.
Due to sharing many of the same beneficial properties with Tungsten, such as its extreme heat and corrosion resistance, Molybdenum has been widely considered a viable substitute. Also, due to its generally more stable price, Molybdenum can be seen as a favorable option when a more financially economic material is needed for producing a product or application.
Yes, the great versatility of Molybdenum alloys does make them very valuable for industry use, which is why we are seeing more of these metals used in myriad industrial applications today.
