You may not know that Molybdenum is one of the 90 naturally occurring elements.  It is actually a rare element.  Classified as a refractory element with a melting point of 2620 degrees Celsius.  The name of this metal comes from the Greek word for “heavy”.  In fact, Molybdenum used to be confused with lead because it is combined with lead in wulfenite.  C.W. Scheele was the first to recognize the difference between these two elements and is considered the discoverer.  The largest deposits of Molybdenum are found in the USA (primarily Arizona, Colorado, and New Mexico), it is also found in the Canadian province British Columbia and in copper mines in Chili.

After processing the Molybdenum, it becomes a powder which is preceded into rods or plates., this process is the reason Molybdenum is so strong, and dense. Molybdenum is also used to make wire which is used in lighting due to its electrical resistance.

Electro Arc makes the Molybdenum Electrodes we sell, which means swagging, large diameter wire is rolled and drawn at high temperatures, small diameter wire at low temperatures.  Electro Arc uses high purity, unalloyed, un-doped, metallic molybdenum containing a minimum of 99.95% molybdenum.  Pure molybdenum has a melting point of 2620 degrees Celsius.

This makes it great for supporting wires in headlight lamps for cars and motorcycles, parts of electron tubes, and annealing boats.  Of course, we make Electrodes with them as they are the longest-lasting option and can easily disintegrate through carbide.

Molybdenum also has the remarkable quality of corrosion resistance.  Round bars supplied in straight lengths are referred to as rods.  These rods are referred to as electrodes in the case of the Electro Arc application for use with our metal disintegrators.  Formerly the term was disintrode, and was available in both solid and hollow, now only hollow electrodes are used with Electro Arc machines.

Molybdenum provides an advantage when using a metal disintegrator because the melting temperature has double that of other electrode materials.  This equals faster disintegrating time and lower cost for you.  In comparison, copper erodes rapidly which raises your labor cost.  Of course, Molybdenum is more expensive than copper initially, however, the savings in labor more than justifies this expense.  Thousands of disintegrator customers just like you use molybdenum in the electrical discharge process.
