    Product Description

    Tungsten powder is an important metal powder with high density, high melting point, good mechanical properties and chemical stability. It is widely used in the manufacture of high-speed steel, cemented carbide, rocket engine components, electronic devices and other fields. Tungsten powder has different shapes and particle sizes and can be used in different fields. Fine tungsten powder can be used to manufacture electronic devices, catalysts, etc. Coarse tungsten powder can be used to manufacture high speed steel, cemented carbide and so on. In addition, tungsten powder can also be mixed with other metals or non-metallic elements to prepare alloys or composite materials with better properties.
