WKM material is tungsten doped with ppm levels of potassium (K), aluminium (Al) and silicon (Si). It is produced principally as rod and wire. The combination of doping and highly directional deformation develops a longitudinal grain structure, which results in an increased recrystallization temperature, improved high-temperature sag-resistance and greater corrosion resistance against molten metals. WKM is used as single or multiple-stranded wire for evaporation coils and furnace elements.
