Alumina ceramic tubes are made from high-purity alumina material through high-temperature sintering, offering excellent mechanical strength and dimensional stability. The single-hole channel design ensures smooth conduction, while the short section structure facilitates precise installation in compact spaces. These tubes provide outstanding electrical insulation properties and exceptional thermal stability.

Specifications: Material is 99% aluminum oxide (Al₂O₃) with a density of 3.9g/cm³. Available sizes include 1.7×4×4.2mm, 2.3×3.1×15mm, 2.4×5×5mm, and 2.9×4.7×19mm. Package includes 10 pieces of alumina ceramic tube.

Widely used in electronic equipment, sensor housings, gas conduction, and scientific research experiments. Please allow slight measurement error due to manual measurement. Monitor calibration may cause slight color variation from actual item.
