White tungsten wire
Black tungsten wire after caustic wash or electrolytic polishing. Compared with the surface of black tungsten wire, the surface of white tungsten wire is smooth, bright and clean.White tungsten wire aftercaustic wash is silver gray metallic luster.
• 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.
