Tungsten rods are solid cylindrical bars made from the metal tungsten. Tungsten is a refractory metal known for its high melting point, exceptional hardness, and excellent resistance to heat, wear, and corrosion. Tungsten rods have several applications across various industries. Here are some common uses:

Electrical and electronic industry: Tungsten rods are used in electrical discharge machining (EDM) and high-temperature applications where their high melting point and good electrical conductivity are valuable. They are also used as heating elements in vacuum furnaces and as filaments in incandescent light bulbs.

Aerospace and defense: Tungsten rods find applications in the aerospace and defense sectors due to their high density and strength. They are used in the production of counterweights, ballast weights, and balance weights in aircraft, missiles, and other defense equipment.

Welding and electrodes: Tungsten rods, particularly those alloyed with other metals like thorium or lanthanum, are used as electrodes in Tungsten Inert Gas (TIG) welding. These rods provide stable and reliable arc performance and are commonly used in industries such as automotive, aerospace, and construction.

Medical and radiation shielding: Tungsten rods are utilized in medical equipment and radiation shielding applications due to their high density and radiation absorption properties. They can be used in X-ray machines, radiation therapy devices, and nuclear power plants to protect against radiation exposure.

Chemical and industrial applications: Tungsten rods are used in chemical reactors, heat exchangers, and other equipment that requires resistance to corrosive environments. Their high melting point and chemical stability make them suitable for handling corrosive substances.

Filament wires: Tungsten rods can be drawn into fine wires and used as filaments in various applications, such as incandescent light bulbs, electron microscopes, and cathode ray tubes.
