Wire Types

Elmet produces two types of molybdenum wire; pure and HCT. Diameter sizes range from 0.001 inches to 0.250 inches. 

The pure wire products find use in most standard applications for production of mandrels, supports, furnace elements, furnace windings and formed parts. HCT is a potassium silicate doped product which has a higher recrystallization temperature and for diameters below 0.090 inches it exhibits better ductility after recrystallization. It is used in more demanding applications such as for halogen lamp leads where it provides superior weldability and glass-to-metal seal properties.
