Using PVD thin film deposition technology, SMI Ltd. is able to supply planar and rotary tungsten metal sputtering targets. Products are adapted to meet the specific requirements of clients.

 

Classification Characteristics Applications W31 Standard doped tungsten with excellent non-sagging property. Filaments for bulb lamps and fluorescent lamps, heaters for electron tubes. W41 Tungsten wires with re-crystallization point lower than that of W31 and excels in reforming. Vacuum metalizing material and high temperature structural material. W91 Excels in non-sagging property and a best fit for high temperature use. Filaments for halogen lamps. W99 Tungsten wires with re-crystallization point higher than that of W91 and excels non-sagging property Filaments for halogen lamps with longer life. WKMT10 Thoria Tungsten Wire (and Rods). Commonly used in inert gas welding (TIG) and plasma welding. Can carry 50% more current than tungsten, and produces a more stable arc. Prematerial for lamp electrodes are available at diameters from 0.25 to 2 mm. Filaments for magnetrons for microwave ovens
