One of the world's major producers of molybdenum and rhenium powders is Herman C. Starck Berlin (HCST). Annual production today is in the region of 500–600 tonnes of molybdenum powder and some 4500 kg of rhenium powder. Metal Powder Report recently had the opportunity to visit HCST's plant in Goslar, Germany, and reports …

Arizona copper mines also produce the economically important trace metals rhenium and molybdenum, which are primarily used in steel and other alloys. Arizona has one active gold mine (Moss Mine, Mohave County) and other deposits of silver, gold, lead and zinc are also in the process of being developed into mines. ... (copper - #1 and molybdenum ...

Most rhenium occurs with molybdenum in porphyry copper deposits. Identified U.S. resources are estimated to be about 7 million kilograms. Rhenium also is associated …

The choice between high-speed steel and sintered carbide (C2 Grade) depends largely on production quantities. In either case, tool life is shorter than would be expected with steel because molybdenum is considerably more abrasive than steel at the same hardness, and molybdenum has a tendency to chip while being machined.

W-Re alloy is an alloy of tungsten and rhenium. One type of the alloy is low rhenium alloy with rhenium under 5%, the other is high rhenium alloy with rhenium of 20% ~ 30%. Rhenium is a rare metal, scarce and expensive. Molybdenum alloy can be added 2% ~ 5% rhenium which can improve the plasticity and strength of molybdenum.
