Rupal Metals is a prominent producer and supplier of premium-grade Tungsten Bars and Rods located in Delhi, India. Acclaimed for precision, quality, and reasonable pricing, Rupal Metals serves the extensive industrial needs of the nation and world. Established years ago with a strong focus on quality assurance, the company produces products according to international standards of strength, density, and resistance. For aerospace, electronics, or industrial machinery applications, Rupal Metals guarantees timely delivery, technical assistance, and customer satisfaction, earning it a renowned name in Tungsten-based components.
Rupal Metals’ Tungsten Bars and Rods contain more than 99.95% pure tungsten, guaranteeing outstanding density (19.3 g/cm³) and melting point (3422°C). These bars demonstrate superior hardness, tensile strength (up to 1000 MPa), and low thermal expansion. The mechanical characteristics are high heat conductivity, excellent corrosion resistance, and fine wear resistance. These characteristics combined make them best suited to operate in high-stress and high-temperature conditions. Rupal Metals applies strict quality control to keep the structural integrity and accuracy of the material intact for industrial and commercial-grade application.

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.
