Thorium tungsten needle

Thorium tungsten needle Changxing brand consumables aim is: quality first, customers first, credit first. Warmly to inquire telephone 0315-8139919 15176607956 ---------- main production WC20 cerium tungsten needle (electrode) WC20 cerium tungsten electrode tungsten needle (electric WC20 cerium tungsten great) WC20 cerium tungsten electrode argon wholesale sale tungsten arc welding electrodes. Range, quality assurance. Cerium tungsten electrodes, tungsten electrodes thorium, 1.6 * 150mm, 1.6 * 175mm, 2.0 * 150mm, 2.4 * 150mm, 2.4 * 175mm, 3.2 * 150mm, 3.2 * 175mm, 4.0 * 150mm, 5.0 * 150mm and so complete specifications, quality assurance , priced at wholesale. Non-radioactive material. Electron emission capacity than the high thorium tungsten, arc voltage is low, stable arc. Positive polarity, the allowable current density of 5% -8% over the thorium tungsten, exchange high allowable current density, long life, suitable for DC or AC welding and the use of time in the same amount of longer than thorium tungsten. Typically used for welding carbon steel, stainless steel, titanium and other metals. Grade quality ingredients Composition adding 1.80-2.20% CeO2 added oxide impurities% ≤0.02% margin Remainder WT20 tungsten thorium tungsten electrode WC20 cerium tungsten electrode pure tungsten electrode WL15 WP blue tungsten electrode WL20 (lanthanum tungsten 20 #) WZ8 (zirconium tungstate 8 #) I plant has a set of scientific and strict management system and procedures, from product design, development, production through to sales and service all aspects to ensure strict quality requirements. The main products are tungsten series products: tungsten filament, tungsten, tungsten rod, tungsten needle, tungsten tube, thorium tungsten electrodes (WT20), cerium tungsten electrodes (WC20), pure tungsten electrodes (WP), blue tungsten electrode (WL15), other tungsten products, molybdenum products: molybdenum wire, molybdenum, molybdenum rods, molybdenum plates and other molybdenum products Our tenet is: quality first, customers first, credit first. Warmly to inquire. : High melting point, arc stability, no self-consumption. Tungsten added 0.15% to 4% of ThO2, ZrO2, LaO2, CeO2, YO2 reduce the burning of tungsten, increase its life, do not pollute the weld; increase the tungsten electron emission capability, so that from the arc current, arc stability current, arc gap, broken arc gap, and therefore high weld quality.
