Products Description
Tungsten rods are made of tungsten, a rare metal known for its remarkable properties. Tungsten is characterized by its high melting point, resistance to corrosion, and excellent mechanical strength. These features make tungsten rods ideal for a wide range of applications in various industries. Tungsten's exceptional density and durability make it ideal for use in high-temperature environments. Its resistance to thermal shock and chemical erosion make it a reliable material for non-reactive container linings and laboratory equipment. Tungsten rods' remarkable properties make them highly suitable for use in nuclear power plants and other similar applications where strength, durability, and high-temperature resistance are essential.

Tungsten rod's characteristics such as high hardness, high density and high temperature resistance make it an indispensable raw material in the field of industrial manufacturing. In fields such as chemical industry and electric power, tungsten rods can be used to manufacture electrodes, furnace wires, high-temperature heaters, high-temperature stoves, etc.
Mechanical processing
Tungsten rod is a key material for manufacturing cutting tools, drill bits and milling cutters. Tungsten steel blades have the characteristics of high hardness, good wear resistance, and not easy to deform, and are often used to process hard materials. Tungsten steel milling cutters can be used for high-speed machining, with high wear resistance and advanced machining accuracy.
Aerospace
In the field of aerospace, tungsten rods have become one of the main materials for manufacturing high-performance aerospace devices due to their high strength, high stability, and high melting point. For example, tungsten alloys can be used to make rocket nozzles and components in engine propulsion systems that need to withstand high temperatures and pressures.
Medical devices
Tungsten rods can be used in the manufacturing of medical devices. For example, tungsten steel blades, mushroom-head needles and other medical devices use tungsten rods as materials. Tungsten rods are also growing in importance in medical device manufacturing.
Packaging, labeling and storage
Standard individual packaging: the rods are either bundled (Ø < 6 mm) or packaged individually.
Rod sections < 25 mm long are also packed as bulk goods, depending on the diameter
Each transport packaging is marked with an adhesive label;
Store the material dry and protected from mechanical damage, if possible until left in the original packaging for actual use.
Special packaging: (additional costs will be charged)
For particularly aggressive storage conditions (e.g. sea air) we recommend special packaging.
