Electronic mechanical tungsten rod can be used in making the electricity photo source, the automobile and the tractor light bulb, make lattice side rod, framework, leading wire, electrode, heater and contact materials and so on.
Electronic mechanical tungsten rod is the best choice for the excellent high-temperature characteristics. Tungsten heating elements is used almost exclusively in vacuum furnaces for higher temperature ranges (1800 to 3000 C for example). The heating element operates at a higher temperature than any other component in the system.
Tungsten rod for electronic mechanical heating element design takes into account thermal capability, mechanical stability, and configuration and service life. The heating element is the most critical part of the system in terms of material choice.
