You will learn everything about the process, features, specifications, and critical parameters, amongst others.

Keep reading to learn more.

What Is Cold Drawn Aluminum Tubing?

Cold drawn aluminum tubing is a special type of aluminum tubing that you will manufacture through cold drawn method.

Cold drawing process

The cold drawn aluminum tubing is special because it has uniform tolerance, increased strength and enhanced machinability.

Aluminum tube

Is There Difference Between Cold Rolled Aluminum Tubing And Cold Drawn Aluminum Tubing?

Yes, there is a difference between cold rolled aluminum tubing and cold draw aluminum tubing.

First, you have to note that you will perform both cold rolling and cold drawing at room temperature.

Cold rolled aluminum tubings are often flat in comparison to the cold drawn aluminum tubings that are thin shaped.

Cold drawing is a process where a metal is pulled through a die without passing it through heat.

Usually, cold drawing changes the mechanical properties of the aluminum metal thus giving it a very bright finish.

Cold rolled aluminum tubings are special types of tubes that you can make using different pairs of rolls.

Cold rolling is responsible for increasing the strength of the aluminum metals as well as the surface finish.

Cold rolling process

What Is The Difference Between Cold Drawn Vs. Hot Rolled Aluminum Tubing?

You can opt for different types of aluminum tubings among them being cold drawn and hot rolled aluminum tubings.

You may, however, go through a hard time trying to establish the most suitable type of aluminum tubing among them.

Well, here is a comparison between the cold drawn aluminum tubing and hot rolled aluminum tubing.

Cold Drawn Aluminum Tubing

You will process the cold drawn aluminum tubings at room temperature to produce thin shape tubings.

It involves turning and pulling of aluminum through a die to make the final elongated shape.

You can use the cold drawn aluminum tubings for longer products such as structural parts and shafting.

Apart from that, it is the most ideal aluminum tubing that you will use to improve aesthetic value for consumer products.

Hot Rolled Aluminum Tubing

This is a flat aluminum tubing that you will manufacture using rollers at very high temperature.

Usually, you will change the size and shape of the hot rolled aluminum tubing as it cools down slowly.

You should avoid using the hot rolled aluminum tubings in applications that require uniform thickness.

In addition to that, you will get a rougher finish on the hot rolled aluminum tubings with very low strength.

How Does Cold Drawn Vs. Extruded Aluminum Tubing Compare?

The main difference between the cold drawn aluminum tubing and extruded aluminum tubing is mode of formation.

Here is a comparison between the manufacturing processes of cold drawn aluminum tubing and extruded aluminum tubings.

Cold Drawn Aluminum Tubing

Just from the names, you can note that cold drawn aluminum tubings are from the cold drawing process.

Here, you will force aluminum through a formation die before stretching it o form the desired shape.

After that, you will push the aluminum through a second die where cold working or cold drawing takes place.

You should also understand that the process of clod drawing happens under room temperature.

You will determine the final dimension of the cold drawn aluminum tubings through plastic deformation which involves bending and compression.

Extruded Aluminum Tubing

On the other hand, you will make the extruded aluminum tubings using the extrusion manufacturing method.

It involves pushing heated, soft and malleable aluminum billets through a shaped die before cooling.

In this case, you will perform the extrusion process at high temperatures in comparison to cold drawing.

Different colors of extruded aluminum tube

What Are The Benefits Of Cold Drawn Aluminum Tubing?
