What is cold drawn aluminum tube?
Cold drawing is a process where an aluminum tube is drawn through a die at room temperature to reduce its cross-section and increase its length. The specific process includes:
Pre-treatment: The raw aluminum tube needs to be annealed or heat-treated to achieve a certain degree of ductility.
Drawing: The aluminum tube is drawn through a die under drawing force, reducing its diameter and increasing its length to the desired specifications.
Post-treatment: After drawing, the aluminum tube may require surface treatment, straightening, cutting, and other further processing to meet the final requirements.

What characteristics of Cold Drawn Aluminum Tubes?
High Precision: Cold drawing and cold rolling processes can produce aluminum tubes with very high dimensional accuracy and small tolerance ranges.
Good Surface Quality: The surface of cold drawn or cold rolled aluminum tubes is smooth and requires minimal subsequent processing.
Improved Mechanical Properties: The strength and hardness of the aluminum tube are enhanced through cold working, meeting higher usage requirements.
Variety of Specifications: Able to produce aluminum tubes of different cross-sectional shapes and sizes to meet various design needs.
What applications of drawn aluminum tubes?
Due to their excellent mechanical properties and high precision, cold drawn and cold rolled aluminum tubes are widely used in the following fields:
Aerospace: Used to manufacture lightweight, high-strength structural components such as aircraft frames and conduits.
Automotive Industry: Used to produce high-precision hydraulic lines, brake system components, etc.
Mechanical Manufacturing: Suitable for manufacturing high-precision bearings, hydraulic cylinders, and other mechanical parts.
Architectural Decoration: Used to produce high-quality decorative aluminum tubes such as railings and handrails.
Electrical Engineering: Used to manufacture cable protection tubes, radiators, etc.
The choice between cold drawing and cold rolling processes mainly depends on the final product requirements and material characteristics. Through reasonable process control, aluminum tubes can be produced to meet various high demands.
