Specialty Metals

High-purity tungsten for extreme-temperature and high-density industrial applications.

Distefano Consulting provides international sourcing of high-purity tungsten for companies that require the highest melting point of all metals, exceptional density, and reliable performance in extreme-temperature and high-stress environments. We connect buyers with qualified manufacturers producing tungsten in compliance with ASTM B760, ensuring material integrity and batch traceability.

Technical Description

Tungsten possesses the highest melting point of all metals (3,422 °C), the lowest vapor pressure, and one of the highest tensile strengths at elevated temperatures, making it indispensable for extreme-temperature applications. With a minimum purity of 99.95%, our tungsten is suitable for demanding technical applications across multiple industries. The material is available in fine wires (diameter 0.04 mm to 8 mm), bars, sheets, plates, and discs, supporting uses from precision filaments to heavy-duty radiation shielding. Tungsten's exceptional density (19.25 g/cm³) also makes it a preferred material for counterweights, kinetic energy penetrators, and radiation protection in medical and nuclear settings.

Grades and Compositions

We supply tungsten with a minimum purity of 99.95%, meeting the stringent requirements of lighting, welding, electronics, and defense industries. This high-purity grade ensures consistent mechanical properties, dimensional stability, and reliable performance at extreme temperatures. Specialty tungsten alloys, such as tungsten-copper (WCu) and tungsten-heavy alloy (WHA), may be sourced upon request for applications requiring tailored thermal or density characteristics.
