Product Descriptions

Tungsten wire is a high-performance metal wire, usually made of tungsten alloy. Its product structure is mainly composed of fine wires made of tungsten alloy and special ceramic materials, used to improve its high temperature resistance and oxidation resistance. The production process of tungsten wire includes using single or multiple strands of tungsten wire to wrap and produce. During the production process, the tungsten wire will undergo a secondary inspection to ensure that the wire diameter is uniform, without internal cracks, splits, continuous pits, scratches, and other issues, in order to meet high-quality requirements.
