Molybdenum Alloys for Making Molybdenum Products Molybdenum (chemical symbol Mo) is a strong metal with excellent thermal conductivity, low heat resistance, high strength but considerably lighter than the other similar metals. With these fine qualities, molybdenum products are highly accepted and have wide range of usages. It mainly exists in an alloying form, doped commonly with elements of nickel, cobalt, chromium, and tungsten. These products have wide applications in the chemical industries, the aerospace research and development, marine biotechnology as well as various medical applications. Molybdenum products, namely molybdenum alloys, are commercially available in many forms and compositions. This enables users to choose from a wide range of products the particular product that suits their requirements appropriately.

There are mainly two established procedures of manufacturing these alloys. These are namely vacuum arc-casting (VAC) and powder metallurgy (PM). These two consolidation procedures are the most popular, cost effective and most widely followed procedure to produce a molybdenum product, and he commercial production of molybdenum alloys are mainly by these two methods.

Some of the most commonly found alloys of the metal are listed below: 1. TZM alloy: an exceptionally strong alloy that offers least weakness, high resistance at very high temperatures. It is the most widely used alloy of molybdenum. The alloy contains 0.5% titanium and 0.08% zirconium apart from Mo being the principal component. 2. MHC alloy: an alloy of molybdenum and hafnium carbide, this alloy has an amazing strength, low thermal expansion, and high thermal conductivity that make this alloy ideally suited for die applications, particularly for brass extrusion. Besides, MHC alloy works under extreme mechanical and thermal loads since the carbon is uniformly distributed from a microscopic view of this material. 3. Mo-30W alloy: a widely used alloy for commercial purposes, this molybdenum and tungsten alloy is highly effective in handling high temperature substances like molten zinc. 4. MP35N: an alloy based on the combination of chromium, molybdenum, nickel and cobalt being the basal components. It has an outstanding strength and corrosion resistance. This

accounts for its ideal for applications in the aerospace, marine, chemical, and medical fields. 5. ODS Mo-La alloy: an alloy of molybdenum and lanthanum oxide, which is of high strength, ductility and great thermal resistance that leads to its wide applications that require dimensional and strength at extremely high temperatures.

Molybdenum alloys including the above-mentioned are used to produce industrial molybdenum products commonly seen as molybdenum rods, tubes, wires, plates, bars, billets, forgings, crucibles, mandrels, powders, etc. these products are also used as sintering trays, as sputtering targets for a number of activities like flat panel display, photovoltaic, etc. The exceptional strength, ductility, thermal resistance and capability of recrystallisation are some of the major characteristics on molybdenum products and have led to wide industrial applications as these characteristics are rarely found in molybdenum or the other alloy metals separately.

At present, there are a lot of research initiatives going on worldwide, related to molybdenum and its composite materials. Most of these studies focus on finding new-type material and different efficient ways in which the metal can be used for wider applications for the sake of mankind.
