Lighting: Used as mandrel wire for manufacturing of tungsten filaments. Also used in lamps for pins and support hooks
Electron tubes: Moly rods are used as heater element and supports in electron tube because of their good electrical conductivity and good mechanical propertiesat high temperature.
High temperature furanaces: Moly in wire ,rods and strip form is used as a heating element in high temperature furanaces operating about 1300°C.
Welding electrodes: Moly rods are used as electrodes in spot welding machines.
Semi conductors: Thermal expansion of moly closely matches that with silicon.This allows the use of moly as supports and contacts for silicon in semi conductors.
Other applications: Special bolts,screw and machined parts.Cupels for the evaporation of metal such as silver and gold.
