Rhenium-tungsten (Rheni-tung®) Targets (Rotating Anodes)

Tungsten has a high melting point and generates X-rays when irradiated with a high-speed electron beam. Because of these properties, it is used as an X-ray source for various X-ray tubes used in medical and security devices.
Toshiba Materials produces targets with Rheni-tung®, an alloy that is extremely strong and tough (resistant to cracking and swelling). These include standard Rheni-tung® targets in which Rheni-tung® is combined with a molybdenum alloy, and Rheni-tung®/graphite targets in which some of the molybdenum alloy is replaced with graphite for a lighter weight. These targets are used for medical X-ray tubes.

Probe Pins

Tungsten is a strong, wear-resistant metal that is used make probe pins (contact pins) for inspecting high-density integrated circuits in parts such as semiconductors and liquid crystal panels. Toshiba Materials has developed Rheni-tung®, an alloy in which rhenium is added to tungsten to further improve its properties. In addition to high strength and electrical conductivity, Rheni-tung® can be formed into smooth pin points using trace element control technology, making it ideal for probe pins.
