Tungsten Bars and Rods mainly contain high-purity tungsten, often over 99.95% pure, which ensures exceptional strength and stability. This material has impressive mechanical properties, like a very high melting point of 3,422°C, significant density (19.3 g/cm³), and superior hardness. It retains excellent tensile strength, wear resistance, and dimensional stability, even at high temperatures. Tungsten’s low thermal expansion and high modulus of elasticity make it a great choice for critical applications that require mechanical strength under severe thermal and mechanical stress.

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.
