Aluminum round tube

So in this section, I want to take you through some of the basic things that happen during the manufacturing process of this particular material.

Basically, it starts with determining the size of the billet that you’ll need to use as raw materials.

Remember the billets ordinarily are long; hence, you need to cut them down to a particular size of depending on your preference or that of the client.

The next step is to pre-heat the billets and then heat them to an appropriate temperature depending on the specific requirements.

You then exert pressure which estimated to be over 10, 000,000 pounds to push the aluminum through the standard extrusion die.

This intense pressure leads to the creation of solid and hollow aluminum tubes.

These hollow aluminum tubes are then cooled down on large flat surfaces, stretched out and then cut according to your preference.

Additionally, hardening of the aluminum round tube also takes place by heating to help in bringing out its inherent qualities such as corrosion resistance and durability.

Primarily, that’s what is involved in the manufacturing process of this particular type of aluminum material.

But you also need to take note of the fact that on paper, the process might look quite simple.

However, in reality, it is quite involving and thorough hence the need for having all the necessary equipment to that effect.

How to Fabricate Aluminum Round Tubing
