Material Introduction
Potassium Tungsten
Material Introduction
The main component of tungsten-potassium alloys is W-(15ppm-100ppm)K. By adding K to tungsten, the potassium bubbles formed can pin down dislocation movement, prevent grain boundary migration, and refine grain size.
Specifications and Performance
| Material | Bar /mm | Plate/mm |
| WK | Φ 1~70 | 0.5~50 |
Fabrication Process
Tungsten and its alloys are rolled, forged, and drawn to reach or approach their theoretical density, while improving strength, plasticity, and toughness. These alloys are widely used as high-temperature furnace components and electronic tube components.
Advantage
By adding K to tungsten, the potassium bubbles formed can pin down dislocation movement, prevent grain boundary migration, and refine grain size. Compared with pure tungsten, tungsten-potassium alloys exhibit outstanding high-temperature strength and creep resistance.
