Beschreibung

• Description Product name: high-purity tungsten wire, electrode wire, white tungsten wire, black tungsten cord Purity: W≥99% Basic knowledge of tungsten wire: Tungsten wire, a skinny twine made through forging and drawing a tungsten bar Tungsten filaments are mainly use in electric gentle assets similar to incandescent lamps and halogen lamps The resistivity of tungsten twine is 5*10^-8 Tungsten has a high melting point, high resistivity, nice strength, and low vapor stress It is a reputable materials for making incandescent filaments amongst all natural metals But tungsten is tough and brittle, and it is tough to process When the current passes throughout the tungsten wire and is heated to a definite temperature, the resistance value of the tungsten wire additionally increases to a definite cost (generally, the resistance price of the steel cord will increase because the temperature rises) The resistance of this object should be 1370°C-2000°C at room temperature, however the resistance value will substitute when the size of the cross-sectional subject of the tungsten cord modifications Notice: 1 Due to handbook measurement, please allow a slight deviation in size 2 Due to the affect of sunshine and reveal brightness, the color tone of the photo could also be slightly varied from the actual task
