Feature
• High temperature performance
- 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 customer’s requirements.
Straightness 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 pints with distance of 100mm is 10mm;
•Surface conditions
- Smooth surface, free of splits, burrs, cracks, dents, dots, grease contamination.
