1. Properties of the products :high melting point ,steady electric arc ,without self-consume .Tungsten increasing 0.15-4% Tho 2 ,Zro 2 ,Lao 2 ,Ceo 2 ,which can reduce the loss of tungsten pole ,prolong its life ,not pollute the welding seam ,increase launching ability of tungsten pole electrons and so on Therefore ,the quality of welding seam is high. 2. Export tungsten electrodes execute ISO 6848 international standard and AWS5.12.

3. Size and size tolerance.

   Diameter:Φ0.1-15mm

   Diameter tolerance:≤Φ2.5mm±0.05mm,

   >Φ2.5mm±0.1mm ,

   Length tolerance:±1mm 4. Flat degree :not large 0.5% length of electrodes. 5. Quality of surface :smooth ,clear ,no defect ,no greasy dirt and other impurity.6. The end surface of electrodes should be even ,smooth and no burrs ,no section and no internal defect.
