Tungsten powder description
Tungsten powder is a fine, grey-black powder that is derived from the metal tungsten. It is known for its high melting point, extreme hardness, and excellent strength. The powder is often used in various industries and applications, such as manufacturing tungsten carbide, which is widely used in cutting tools, drilling bits, and wear-resistant parts.
Tungsten metal powder has a very high density, making it ideal for applications where weight is a critical factor. It is also highly resistant to corrosion and has a low coefficient of thermal expansion. These properties make tungsten powder suitable for use in industries like aerospace, defense, electronics, and automotive.
The particle size of tungsten metal powder can vary depending on the desired application, with sizes ranging from a few micrometers to several hundred micrometers. The powder is typically produced through a series of processes such as grinding, milling, and sintering.
Tungsten powder application
Tungsten powder has a wide range of applications due to its unique properties, such as high density, high melting point, and low thermal expansion coefficient. Here are some common uses for tungsten powder:
-
Filaments: Used in incandescent light bulbs and fluorescent lamps for coating filament wires due to its high melting point and thermal shock resistance.
-
Alloying: Added to various alloys, such as tungsten-nickel-iron, for use in heavy metal components like aircraft counterweights and medical radiation shielding.
-
Electrical Contacts: Used in manufacturing high-current electrical contacts, switches, relays, and circuit breakers due to its resistance to electrical arcing.
-
Welding Electrodes: Commonly used in TIG welding for its high melting point and good electrical conductivity, ensuring precise and quality welds.
-
Thermal Spray Coatings: Applied in thermal spray processes to create wear-resistant coatings for protection against erosion, corrosion, and wear.
-
Catalysts: Utilized in catalytic processes like sulfuric acid production and petroleum refining, offering high activity and selectivity.
-
Additive Manufacturing: Applied in additive manufacturing processes like selective laser melting or electron beam melting to create strong, heat-resistant metal parts.
