Product Description Product Description Chemical composition:Tungsten>99.96% Physical properties:Density: 19.3g/cm3Melting point (liquid): 3422°CConductivity: 30% IACS Min,Hardness: 69HRA Min Surface condition:Rough groundedpolished, alkali washed, flatness: ≤2% Tungsten strips of any size can be provided and cut into small tungsten strips using tungsten plate wires.Characteristics of tungsten electrode:Tungsten electrode is widely used in welding due to its properties.Tungsten electrodes are ground or polished and black rods. The final colors are all different and the difference can be distinguished.In tungsten electrodes, it is important that their final color differs as does the tungsten content. When welding, choose the correct tungsten electrode to make the welding easier and more importantly get the best welding. Some important factors to consider in making the right choice are the type of power source (inverter or transformer), welding material (steel, aluminum or stainless steel) and material thickness.Tungsten electrode plays an important role in arc starting, arc stability and welding quality in tungsten argon arc welding. The mass loss of the tungsten electrode occurs under the high temperature of the arc, which is called ablation of the tungsten electrode. In order to facilitate the discussion of the ablation mechanism of tungsten electrodes, ablation can be divided into ablation of added oxides and ablation of tungsten itself.Other Pure tungsten ProductsPure tungsten Rod Pure tungsten plates, pure tungsten strips, and pure tungsten sheets are plate shapes made from tungsten billets through hot rolling, leveling, and cold rolling processes. Strips, rods and other pure tungsten profiles. Tungsten has a high melting point, high temperature strength and creep resistance as well as thermal, electrical and The electron emission performance is good and the specific gravity is large. Low expansion coefficient metal vapor pressure. Generally, powder metallurgy is used.
