Specification :

usage field: arc welding in inert gases atmosphere, and ion welding, cutting , spray, manufacture electrodes.
Character: high melting point, stability in arc, no wastage.the electrodes can last even longer when put ThO2 TrO2 LaO2 CeO2into pure tungsten.it also no pollution to welding slots .it will increase the ability of electronic spray and welding part more perfect.
The electrodes can live up to ISO6848 international standard, American SWSA5.12-95 standard.please see the mainly component in the following sheet.
Lanthanated tungsten ( WLa) electrodes thorium tungsten ( W-Th) electrodes Zirconium tungsten ( W-Zr) electrode yttrium tungsten ( Yt-W) electrode composite tungsten ( wrex) electrodes.
