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.
Features
- Strong and compatible with high-output electron beams
- High precision; shafts will not lose precision at high rotations
- High strength, toughness and heat resistance

Examples of uses
- Medical X-ray tubes (standard X-ray tubes, X-ray tubes for CT scanners, X-ray tubes for circulation devices)
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. It has high strength and high conductivity, and at the same time, it has a smooth pin tip due to trace element control technology, making it suitable for probe pins.
Features
- Outstanding electrical conductivity, strength and wear resistance
- Extremely smooth pinpoint surface

Rhenium-Tungsten (Rheni-tung) Wires
Rhenium and tungsten have different electrical resistance and mechanical properties, and the electrical resistance and mechanical properties of the Rheni-tung alloy change depending on the amount of rhenium added to tungsten. Toshiba Materials has a lineup of wires that can be applied to various applications by taking advantage of the characteristics of tungsten.
Features
- Homogeneous and highly functional with few cracks
- Wide range of wires with a variety of properties
