Molybdenum sheet

Molybdenum sheet is used for heater of electronic vacuum furnace and heat-insulation screen, molybdenum round sheet to produce molybdenum boat and electric power semiconductor, and raw materials to make vacuum light house. Forming the molybdenum powder with isostatic pressing, and with the technology of hot rolling, annealing, washing with alkali, cold rolling ,cutting, leveling off after the molybdenum sheet billet is formed by sintering with medium frequency furnace, also molybdenum sheets have the excellent characteristic of brightness and smoothness on the surface and well reprocessing.

Material from .005 inches to .090 inches in thickness is classified as molybdenum sheet. It is used for fabrication of sintering boats, high temperature furnace heating elements and heat shields. Standard availability is described below. Other sizes and tolerances are available.

The specification of molybdenum sheet

Thickness	Max. Width
.005" to .015"	24"
> .015" to .040"	24"
> .040" to .090"	24"
Length is dependant on surface condition required and width.

Surface condition

Surface can be supplied in a shiny, matte, satin, or as-rolled condition; dependent upon thickness and width parameters.

Heat treatment

Molybdenum flat products are rolled and annealed to provide the optimum condition for the desired end use (Furnace, Punch, Deep Draw).
