Product Description

Vacuum Evaporator Coating polished Tungsten Wire in Spool

Tungsten wire are used to make filaments of incandescent lamps, fluorescent lamps, and halogen lamps, electrodes of HID lamps, heating components, vacuum metalizing coils and TIG welding electrodes. Surface conditions: Smooth surface, free of splits, burrs, cracks, dents, dots, grease contamination.

High temperature property: According to the specific applications, high temperature property requirements are categorized.

Diameter consistency: Weight deviation of two consecutive 200mm wire pieces is less than 0.5% of nominal value.

Straightness: Regular tungsten wire: In accordance with customers` requirements.

Straightened tungsten wire: For the tungsten wire thinner than 100μm, vertical height of 500mm freely suspended wire should not be less than 450mm; For the tungsten wire at or thicker than 100μm, the maximum arc height between

two pints with distance of 100mm is 10mm.
