Non-sag Tungsten Wire
Introduction
Non-sag tungsten wire is doped with the chemical element of K, which can improve the property of non-sagging. During its swaging, there are small holes after adding the K, and the hole will be parallel potassium bubble after drawing. Regularly, there are two kinds of non-sag wire, with different content of K, including 20~40 and 40~80ppm.
