WC20 cerium tungsten needles (electrode) WC20 tungsten tungsten cerium (Ce tungsten great power WC20) WC20 cerium tungsten electrodes 
 Non-radioactive materials. Thorium tungsten electron emission ability than higher arc voltage is low, arc stability. Positive polarity, the allowable current density higher than 5% thorium tungsten -8%, AC allowable current density, long life, suitable for DC or AC welding, and use the same amount of time longer than the case of thorium tungsten. Typically used for carbon steel, stainless steel, titanium and other metals welding. Grade quality ingredients Composition adding CeO2 added oxide impurities% ≤ 0.02% 1.80-2.20% margin Remainder of tungsten 


 WT20 Thorium Cerium Tungsten Electrode Tungsten electrode WC20 WP Lan pure tungsten electrode tungsten WL15 WL20 (La W 20 #) WZ8 (Zr W 8 #) 



 I plant with a scientific and strict management system and practices, from product design, development, production to sales and service to ensure that all aspects of strict quality requirements. 
 The main products are tungsten series products: tungsten wire, tungsten bar, tungsten rod, tungsten, tungsten pipe, thorium tungsten electrode (WT20), Cerium Tungsten Electrode (WC20), pure tungsten electrodes (WP), blue tungsten electrode (WL15), and other articles of tungsten, molybdenum series products: molybdenum wire, molybdenum, molybdenum rods, molybdenum plates, and other molybdenum products. Our tenet is: quality first, customers first, credit first. Enthusiasm you to inquire. 
 : Melting point, high arc stability, no self-consumption. Tim Tungsten 0.15 to 4% of ThO2, ZrO2, LaO2, CeO2, YO2 reduce the burning of tungsten, to life expectancy, do not pollute the weld; increased electron emission capacity of tungsten, so that from the arc current, arc stability current, arc gap, breaking arc gap, so the weld quality.
