Maduka Metals, a leading manufacturer and supplier located in Abuja, Nigeria, is committed to delivering top-notch Tungsten Bars and Rods that are celebrated for their remarkable strength, density, and heat resistance. These products are meticulously crafted to align with international standards, guaranteeing reliability and precision in challenging industrial settings. Maduka Metals is all about providing exceptional tungsten solutions for sectors like aerospace, defense, electronics, and power generation. Thanks to cutting-edge manufacturing techniques and rigorous quality control, the company ensures that every Tungsten Bar and Rod boasts impressive durability, stability, and performance, even when faced with extreme temperatures and pressures.
Tungsten Bars and Rods are mainly made of pure tungsten (W), typically boasting a purity level exceeding 99.95%, and sometimes mixed with small amounts of molybdenum or rhenium to boost performance. They showcase extraordinary mechanical properties, featuring a tensile strength of up to 1000 MPa and a melting point of 3422°C—the highest of all metals. Tungsten also has a high density of 19.3 g/cm³, excellent thermal conductivity, and minimal thermal expansion. These traits make Tungsten Bars and Rods perfect for high-temperature and high-stress applications that demand superior strength and dimensional stability.

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.
You’ll find Tungsten Bars and Rods widely utilized in industries that need materials capable of enduring extreme conditions. In aerospace and defense, they’re used for missile components, counterweights, and high-density ballast. In the electronics realm, tungsten is crucial for electrical contacts, filaments, and electrodes due to its conductivity and heat resistance. The power generation sector employs them in turbine blades and heat shields, while the medical field relies on them for radiation shielding and diagnostic equipment. Plus, Tungsten Bars and Rods play a key role in tooling, welding, and furnace applications where durability and heat tolerance are essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
