Molybdenum’s properties include a melting point of 2610° C, good electrical conductivity and tensile strength at high temperatures, along with low vapor pressure and a low coefficient of thermal expansion.
Because of such characteristics, Molybdenum rods are widely used in the fabrication of heating elements, fasteners, structural components for high temperature HIP, vacuum and hydrogen atmosphere furnaces. It is also of value in the lighting, electronics and semiconductor industries. Applications of metal rod include lamp supports, power tube components and Silicon rectifier mounts.
T & D Materials manufactures and supplies pure, Potassium doped (HCT type) and Lanthanated doped Molybdenum rods. The Potassium doped and the Lanthanated doped products are targeted for use in higher temperature applications where ductility is retained after recrystallization for material with smaller cross sections.
Molybdenum rod is manufactured as random length pieces or cut to customers’ desired lengths in diameters ranging from .020 inches to 1.75 inches. Standard diameter and length tolerances are listed in the accompanying tables. Other closer tolerances can be quoted on request. In addition, there are three different surface processes or finishes which are provided depending on the desired end use.
- Black Surface is “as swaged” or “as drawn”; retaining a coating of processing lubricants and Oxides.
- Cleaned Surface is chemically cleaned to remove all lubricants and oxides.
- Ground Surface is centerless ground to remove all coating and to achieve precise diameter control.
Custom fabrication is available upon customer request.
