Tungsten Needle Specifications
CTIA tungsten needle is manufactured with high-precision processing, offering a wide range of specifications with diameters from Φ0.05–3.0 mm and lengths from 10–300 mm, meeting diverse needs such as micro probes, minimally invasive applications, precision testing, and industrial discharge. The needle can achieve an aspect ratio ≤100:1, straightness ≤0.1%L, and concentricity ≤0.01 mm, ensuring processing stability and reliable performance. Various diameter and length combinations allow flexible adaptation, from ultra-fine electronic probes to industrial-grade electrodes.
CTIA tungsten needle maintains strict dimensional tolerances. Ultra-fine specifications can reach ±0.001 mm, while standard tolerances are available for applications such as precision spot welding and TIG (Tungsten Inert Gas) welding electrodes. Multiple length options enable short needles for precise positioning and long needles for remote contact or high-temperature industrial use. With precise dimensional control and diverse configurations, CTIA tungsten needle is suitable for industrial manufacturing, semiconductor testing, micro/nano processing, and scientific research.
