A  few days  ago, I asked my collague Sarah who in charge of molybdenum bussiness a question that What Is Molybdenum Bar and What Is Molybdenum Rod? I always can not distinguish molybdenum bar from molybdenum rod cleanly. Now, with the help of Sarah I can do it.

Here, I want to share it with you and wish anyone can give any suggestions or doubt to me in what I mentioned in the following.

What is molybdenum bar and molybdenum rod?

The cross sections of molybdenum bar have many shapes, it may be square, triangular, hexagonal etc., but, if the cross section is round it must be called rod. That to say, the cross section of molybdenum rod must be round and molybdenum bar must not be round.

Also, it may be different in other countries and I would like to listen other voice about it .

Plus:

Molybdenum bar is one popular product made of molybdenum. Molybdenum rod is one round cross section, and cylinder-shape metal made of molybdenum. Therefore, they shares the properties of molybdenum, which are high melting point, good thermal conductivity and low thermal expansion. At high temperature, they can resist oxidation and have high strength without any distortion during the procession, etc.

They just have different shapes in their cross sections, also have different application. For example, molybdenum bar may be  used as molybdenum electrde or processed into molybdenum wire, and molybdenum rod may be processed into molybdenum disc or used as supporting rod etc..
