Small Diameter Aluminum Tubing
Small Diameter Aluminum Tubing
Product Overview
We specialize in manufacturing ultra-precision small diameter aluminum tubing, with outer diameters ranging from φ1 mm to φ25 mm. These tubes are suitable for cutting-edge industries such as medical devices, precision instruments, 3D printing, and semiconductor equipment. We offer both standard tubing and customized solutions based on fluid dynamics and structural strength requirements, ensuring precision, cleanliness, and reliability.
Core Advantages
Ultra-precision control: Utilizing high-speed precision drawing and continuous rolling processes, the outer diameter tolerance is ±0.02 mm, the wall thickness tolerance is ±0.05 mm, and excellent concentricity is ensured. This guarantees stable processing benchmarks.
High-quality material selection: We offer various alloys such as 6061-T6 and 5052-O/H32, which undergo homogenization heat treatment to eliminate internal stress, making them suitable for micro-machining.
High-cleanliness surface: The inner and outer surfaces have a roughness of Ra ≤ 0.4 μm, supporting chemical and electrochemical polishing. Ultrasonic cleaning and dust-free packaging ensure compliance with cleanroom standards.
One-stop service: We provide value-added processing such as custom-length cutting and CNC bending, as well as special treatments including hard anodizing.
