0.8*0.4mm Ultra-fine Alumina Ceramic Tube

Alumina ultra-fine ceramic tubes are advanced ceramic components crafted from high-purity alumina (typically 95% to 99.9% purity) through precision manufacturing processes, including ultra-fine powder preparation, controlled sintering, and micro-machining. Their defining feature lies in their extremely small dimensions, with inner diameters often reaching as low as 0.1 mm and outer diameters starting from 0.3 mm, while maintaining exceptional structural integrity.

Key Properties

• Exceptional Precision: Boasting tight dimensional tolerances (often within ±0.05 mm) and a smooth inner surface finish, these tubes ensure consistent flow and minimal resistance for fluids or gases passing through, critical for high-precision applications.
