Description

Tungsten is doped with 60 to 65 ppm potassium and the material is formed to create wire products with an elongated stacked microstructure. This microstructure gives the material excellent high-temperature properties such as good creep resistance and dimensional stability. Special production steps can be used to make WK65 more load-resistant than WVM.
