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.

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.
