Molybdenum tips welding Electrode is used as an essential part of welding of high conductive metals like copper. It is also used for roller welding and upset welding purpose. Besides having high conductivity level, this type of electrode shaft exhibits good physical stability under high temperature. It contains BeCu and copper. Apart from its good machinability, this electrode shaft is preferred for its accurate composition, long working life, corrosion resistance capacity and fracture proof formation. We would like to introduce ourselves as a growth oriented manufacturer of excellent quality Molybdenum tips welding Electrode.
