Aluminum Tube Cold-drawn Tube
In order to meet the specific technical specifications, we often
use cold-drawn process to prepare aluminum rod materials in line
with the standard. After drawing many times, the cross-sectional
area of aluminum rod is reduced gradually, so the quality and
accuracy of products are improved effectively. For the market
demand for high-quality aluminum alloy pipe, the process is highly
adaptable, has been widely used in aviation, automotive, rail
transit and electronic and many other fields.
The cold drawing process of aluminum tube mainly includes material
selection and pre-treatment, first drawing forming, then drying
treatment, then intermediate drawing, size adjustment and heating
treatment, and finally final drawing to remove defects, after
straightening, carry out acid cleaning, then cold treatment
stereotypes. The initial drawing stage involves placing the
prepared aluminum rod into the machine for precise deformation
treatment, while the intermediate drawing stage involves the
gradual drawing of the steel to achieve the desired aluminum tube
outside diameter And the ultimate drawing uses this method to
remove burrs on the aluminum tube to improve the precision and
surface quality of the product.
Let me introduce you to the unique features of cold-drawn aluminum
tube.
First of all, its precision is very good, so that the aluminum
alloy tube surface smoothness can reach less than 0.02 mm, size
accuracy of 0.05 mm or so.
Secondly, the variety of complex shape is no problem, whether it is
irregular or thin-walled tube, can be easily achieved by cold
drawing technology. Finally, this process can also greatly reduce
the burr, improve the surface quality of the pipe.
Aluminum tube cold-drawing is widely used in the production of
high-precision and high requirements of aluminum alloy pipe,
especially suitable for the following fields: 1. Aerospace
Industry: development and manufacturing of high-speed vehicles such
as aircraft and rockets. 2. Transportation: it can be found in the
manufacture of vehicles such as automobiles, trains and subways. 3.
Electronics manufacturing industry: such as electronic products
packaging and conductive tubes.
Features:
In the reduction of cold production, more rigorous dimensional
accuracy can be in the use of high-precision CNC machine tools with
a tight fit Chuck shows the benefits. In addition, this method can
improve the mechanical and physical properties of the material,
thus improving its machining performance, achieving more subtle
cutting and speeding up chip separation, so that the tool runs more
smoothly. This is undoubtedly a major advantage for our products.
Our company is equipped with advanced automatic production
equipment and testing equipment, its unique compound molding
process production line, strong technical force, testing equipment,
widely used in refrigeration, heating and new energy and other
fields.

(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.
