Molybdenum-Rhenium Alloys

Molybdenum-Rhenium, commonly known as Moly-Rhenium (Mo-Re), is used extensively in industries as diverse as medicine, defense, pure research and production welding. Thanks to its excellent thermal and mechanical properties, this material is a less costly alternative to pure rhenium.
Moly-Rhenium products are available in three standard alloy compositions:

  •  Mo-Re 41%
  •  Mo-Re 44.5%
  •  Mo-Re 47.5%
These materials are available in wire, rod, bar, tubing, foil, sheet and plate. Plus, we now offer arc cast Mo-Re in 47.5% forms. Powders in composite, spherical and spherical alloyed (SMoReP ™) forms are also available in a variety of mesh/sieve sizes, as are traditional flaked powders. Powders are sized by the FSSS, (Fisher Standard Sieve Size) measurement method.
