Molybdenum
Not many metals hold up at high temperature, and fewer still can be worked into thin sheet and wire. Molybdenum is in that rare position.

Why the geometry survives at high temperature
Heating elements that go through repeated heating and cooling cycles do not sag. Form tolerances hold, so the temperature distribution holds with them.
Its expansion coefficient is close to that of AlN and alumina, so interfacial stress stays low in embedded structures. This is the main reason molybdenum is used as the heating element in AlN heaters.
At 10.2 g/cm³ it is about 53% of tungsten. For the same geometry the weight is halved, which helps in large heat-shield structures and moving parts.
Key Properties
The dimensions listed are the range we can supply. Final feasibility depends on the combination of grade, quantity and tolerance and on the material condition you request, so send us a drawing and we will confirm and reply.
