Vacuum or controlled atmosphere furnace hot zones are manufactured using materials that can withstand temperatures in the range of 1315ºC (2400ºF) and higher. None is more common than molybdenum.

The popularity and widespread use of molybdenum in vacuum furnaces is due to the wide range of properties that it exhibits, namely:
Lanthanated Molybdenum is stable up to temperatures in excess of 1500°C (2730°F) with exceptionally good creep resistance and higher ductility (after use at elevated temperature). For these reasons, it is now used for heating elements, hearth supports and structural components.
Whether supplied as sheet, rod, plate, wire, hex nuts or threaded rod, Molybdenum and Molybdenum Alloys are used extensive in vacuum furnace applications.
Molybdenum TZM is an established Molybdenum alloy (0.50 Ti, 0.08 Zr, balance Mo), which is consolidated by either the P/M or vacuum arc-casting processes. It gives excellent service in applications that require high strength and creep resistance at elevated temperatures. TZM Molybdenum Alloy also permits higher service temperatures without softening or weakening.
