Refractory Metals

refractory metalsPrized for their resistance to extreme heat, corrosion and thermal shock, refractory metals have become indispensible to the medical, aerospace, oil and gas and chemical processing industries.

Hard, durable and with melting points up to 3,500 degrees centigrade, high-performance refractory metals such as tungsten and molybdenum have helped make possible many emerging and advanced technologies that were not long ago concepts and dreams.

With outstanding abrasion and wear resistance, high tensile strength and extreme hardness, refractory metals make ideal rocket and turbine engine components because they handle repeated extreme temperature changes and on/off cycles with ease. Their corrosion resistance makes them useful in the oil and gas and chemical processing industries, and their ability to conduct heat and electricity makes them ideal for use in microelectronics.

Refractory metals are often used in the medical device industry because of their ability to withstand high temperature, high stress environments. They are well suited for use in: x-ray tubes; diagnostic-imaging devices; to shield patients from radiation; and for beam collimation.

Refractory metals often cause fits for machinists; the same properties that make them resistant to extreme environments make them very challenging metals from a machinability standpoint. Tube Hollows International has focused significant R&D effort on gun drilling and machining refractory metals during the past several years and has become expert at producing extremely high precision refractory tubing. This tubing boasts industry leading ID surface finish and concentricity tolerances.
