3103 H12 Cold Drawn Aluminum Alloy Tubing For Radiator Extruded
Aluminum Tube
1, Overview
Aluminum tube cold drawing process is a processing method of cold
drawing prepared aluminum rods according to certain process
requirements. By gradually compressing the cross-sectional shape of
the aluminum rod through multiple drawing processes, the surface
quality and dimensional accuracy have been significantly improved.
This process is suitable for producing high demand aluminum alloy
pipes and is widely used in industries such as aviation,
automotive, rail transit, and electronics.
2, Process
The basic process of aluminum tube cold drawing process includes a
series of steps such as bar material selection, pre-treatment,
initial drawing, drying, intermediate drawing, heat treatment,
final drawing, straightening, pickling, and cold treatment. The
initial drawing process involves placing the aluminum rod on a
machining machine for preliminary stretching processing, promoting
the deformation of the bar material. Middle drawing is the process
of pulling a bar in the middle to achieve the optimal external
dimensions for manufacturing aluminum pipes. The function of final
drawing is to eliminate burrs on the aluminum tube, further
improving the surface quality and dimensional accuracy of the
aluminum tube.
3, Characteristics
The aluminum tube cold drawing process has the following
characteristics:
1. High precision: Cold drawing of aluminum tubes can improve the
surface flatness of aluminum alloy tubes to below 0.02mm, and the
dimensional accuracy can also reach about 0.05mm;
2. It can produce various complex shapes of aluminum tubes: The
cold drawing process of aluminum tubes can process various complex
tube shapes, such as irregular tubes, thin-walled tubes, etc;
3. Less burrs: The cold drawing process of aluminum tubes can
effectively reduce burrs on the surface of the tubes and improve
their surface quality.
4, Application
Aluminum tube cold drawing process is a major processing method for
manufacturing high-precision and high demand aluminum alloy pipes,
widely used in the following fields:
1. Aerospace field: production of high-speed transportation
vehicles such as airplanes and rockets;
2. Transportation field: application of aluminum alloy materials
such as automobiles, trains, subways, etc;
3. Electronics field: packaging of electronic products, production
of conductive tubes, etc.
【 Conclusion 】
The cold drawing process of aluminum tubes is an important method
for manufacturing high-precision aluminum tubes, characterized by
high surface smoothness, high dimensional accuracy, and few burrs
of the processed aluminum tubes; Applied in industries such as
aviation, automotive, rail transit, and electronics, it has broad
market prospects.

(Technical requirements refer to national standards or customer
technical quality requirements for production)
Applications:
While extruded aluminum is extremely common in a wide range of
applications, it is not suitable for everything. Any requirement
for elevated properties may turn toward cold finished product as
raw material. Aerospace and defense products requiring high
strength often specify cold finished bar, as well as a host of
automotive applications.
