Pure Thoriated Tungsten Wire

Application:

W 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.

Properties and Characteristics:

1.High temperature property: according to the specific applications, high temperature property requirements

are categorized

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 100um, the maximum arc height

between two pints with distance of 100mm is 10mm

4.Surface conditions: smooth surface, free of splits, burrs, cracks, dents, dots. grease contamination.

5.Coilability no splits or breaks during coiling process

6.Piece weight up to 5kgs for fine tungsten wire, 10kgs for heavy tungsten wire
