Irregularly shaped aluminum capillaries are aluminum alloy capillaries with special cross-sectional shapes. Their core material is typically high-purity or medium-strength aluminum alloys such as 1060, 1100, 1050, and 5052, manufactured through a precision drawing process. These capillaries are characterized by non-circular cross-sections; they may be elliptical, rectangular, polygonal, or other custom shapes to meet the needs of specific applications. Their diameter or cross-sectional dimensions typically range from 0.1mm to 10.0mm, and their length can be customized to a maximum of 8000mm, with tolerances controlled within ±0.05mm to ensure high-precision machining.
