Properties and Characteristics:
1.High temperature property: according to the specific applications, high temperature property requirements.
2.Diameter Consistency. Weight deviation of two consecutive 200mm-wire pieces is less than 0. 5% of nominal
3.Straightness:Regular tungsten wire in accordance with customers' requirements
Straightened tungsten wire. for the tungsten wire thinner than 100um. Vertical height of 500mm freely,suspended wire should not be less than 450mm:for the tungsten wire at or thicker than 10oum, the maximum arc height between two points with distance of 100mm is 10mm
4.Surface conditions: Smooth surface, free of splits, burrs, cracks, dents, dots. Grease contamination.
Tungsten wire mainly used to make filaments of incandescent lamp, fluorescent lamps, and halogen lamps, electrode of HID lamps, heating components, vacuum metallizing coils, and TIG welding electrodes.
Application
