Seismic Tungsten Wire

Seismic tungsten wire having good seismic performance not only has a good seismic performance and impact properties at room temperature and high temperature, also has a high temperature anti-sag property and good winding performance. Seismic tungsten wire is mainly used in lighting system for vibration environment, such as cars, motorcycles, tractors and other vehicles lighting, but it also can be applied to the military lighting field and as a heating wire used in aerospace field engine. Its use is widespread.

Seismic tungsten wire was produced by doping K, Si, Al and other elements into tungsten powder. After studies found that adding K and Al into tungsten powder seismic tungsten wire can not be successfully produced, but the product has excellent processing performance. And doping in the tungsten powder with K and Si obtained seismic tungsten wire has ordinary seismic performance. Only doping with K, Si and Al, you can achieve seismic tungsten wire which has excellent performance. This is because that doping Si is conducive to maintaining oxidation layer’s sponginess and permeability of water during the reduction process, so that the doping will more uniform, but also conducive to obtaining the necessary potassium. Doping Al can improve the potassium content in tungsten powder to obtain high-quality seismic tungsten wire. Doping with K can obtain potassium bubble. The dispersion of potassium bubble which can significantly reduce the low-temperature brittleness of tungsten wire, reduce splitting, making seismic tungsten wire get the best seismic performance.

With the development of science and technology, every industry has strict quality requirements of stringent seismic tungsten wire. To produce excellent performance seismic tungsten wire need to optimize production processes and process improvements, but also need further research and experimentation, making seismic tungsten wire can have broad market prospects in various fields.
