    Tungsten sheet can be produced by many different grades of tungsten steel, it is made by the use of metallurgical methods which is including with ball milling, milling, pressing, sintering.
    Tungsten plates for different purposes in the WC and Co content is not same, but they are wided applied in many fields,because of high tensile strength, good chemical stability (acid, alkali, high temperature oxidation), low impact toughness, low coefficient of expansion, high hardness, high hardness, good abrasion resistance, high elastic modulus, high compressive strength, Thermal conductivity, electrical conductivity.
    The use of specific materials should be selected according to the use of tungsten carbide plates.
