Tungsten rods are not highly susceptible to galvanic corrosion because they are highly resistant to corrosion in most environments. However, if paired with more reactive metals, galvanic corrosion may occur.
Yes, Tungsten bars can be welded using specific techniques such as TIG (Tungsten Inert Gas) welding. However, proper preparation and high heat are required due to Tungsten's high melting point.
Maintain tungsten rods by storing them in a dry, clean area to prevent oxidation. Avoid bending or exposing them to extreme heat. Regularly inspect for damage and handle with care.
Tungsten Bars and Rods find extensive use in industries that require exceptional strength and heat resistance. They play a crucial role in the aerospace, defense, and energy sectors for crafting high-temperature components, turbine blades, and radiation shields. In the electronics field, tungsten rods are utilized for electrodes, filaments, and electrical contacts due to their excellent conductivity. Additionally, they are employed in machining, tool-making, and metalworking industries for producing cutting tools, dies, and heating elements. Thanks to their unmatched durability and stability, tungsten bars and rods are the preferred choice for engineering applications in extreme environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
