Furnace - Leading Edge Metals and Alloys | LEMA

Overview

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.

Furnace replacement parts are in stock! 

The popularity and widespread use of molybdenum in vacuum furnaces is due to the wide range of properties that it exhibits, namely:

  • High melting point, 2620ºC (4748ºF)
  • Low vapor pressure
  • High strength at elevated temperature
  • Low thermal expansion
  • High thermal conductivity
  • High elastic modulus
  • High corrosion resistance
  • Elevated recrystallization temperature, between 800º – 1200ºC (1470º – 2190ºF)
