Where is it used?

If you think this innovative technique is only used in construction, think again. The transportation sector and automobile air conditioners are just some of the few extrusion uses. The furniture industry and telecommunications sector would not be functional if it weren’t for the AE procedure.

For instance, extrusion is used for car chassis and roof rails. They are also components of boats and trucks.

Automobile engineers are using them due to the concerns around emissions from vehicles and improved mileage. They are moving towards using AE for designing lightweight cars and vehicles that can give better fuel economy. They want to keep the environment in mind.

But apart from such complex uses, you can see AE products all around you if you look hard enough. Most everyday objects can only be finished after going through the AE process. Even the monkey bars at the playground have been a part of this factory process.

  • Lightweight

It only weighs one-third of the weight of steel. This alloy is surprisingly lightweight, considering its high strength and durability. There is no wonder that 29 million tons of aluminum are in demand each year globally.

  • High electrical and thermal conductivity

After alloying with other elements, it can be a great conductor used in conductor electrical cables. It is often the first choice of engineers since it is one of the lightest engineering metals found in nature. A good example of its thermal conductivity is the foil used in packaging food and keeping it warm for a long duration.

  • Corrosion-resistant

Why did steel and aluminum become so popular? Because of iron’s property to rust quickly? These alloys have a top layer of oxide which protects them from rusting. After anodizing, this bad boy is good to go rust-free for a lifetime.

  • Versatile

Aluminum is highly malleable and ductile, but it can also be made to look as you desire. Processes of painting and anodizing can give it the finishing you wish to achieve.

What is it used to make?

Now that we know how resourceful the alloy is let’s look at several industries that make lightweight products.

  • Construction

Here is a field where the uses of finished extrusion products are endless. Thanks to their lightweight properties, structural frames are commonly made from aluminum channel extrusions. This can include both permanent and temporary structures, like sheds and greenhouses.

But it’s not just in the big framing of outdoor structures that this alloy comes in handy. The fine details go into the construction and design of a home or office, where you’ll also find plenty of these products. You’ll find it in the making of a sliding door or foldable furniture.

Moreover, it is even used in the equipment used in DIY projects. For instance, t-track channels are used as safe and sturdy components of a drill press and router tables.

Its weather-resistant property makes it perfect for outdoor fences and awnings. Not only will such products last longer throughout all seasons, but they’ll also look good while doing their job.

  • Electronic and electrical engineering

As mentioned above, this metal’s thermal and electrical conductivity is spectacular. It makes it a fine choice for a range of electronic parts. You’ll find that AE technology plays a major role in making power units and computer casings. It’s important for laptops and even everyday cell phones. The glamorous LED lighting in high-end shops and malls is also a result of the AE process.

In 3D printers, you are likely to find the use of the 2020 or 2040 v-rail profiles. Even the small 20x20mm size is very tough and durable. The larger 20x40mm and 20x80mm sizes can be used for more complicated machinery.

Often t-slots can also be used for the same purpose. The only difference between a T-slot and a v-slot is the shape of the grooves on its edges.

Additionally, the excellent thermal conductivity makes for smart solar panel systems and heat radiators smart engineering.

  • Transportation

Auto companies are always looking for lightweight materials in heavy-duty vehicles. The AE process comes as a relief for many. It is used in aerospace engineering to produce small, lightweight parts. The common RV is used to make for easy transportation in all kinds of weather.

  • Display set-ups

You must have come across those fancy exhibitions showing off luxury products and wondered to yourself, ‘how did they assemble this so quick? Well, the answer is extruded material. These pieces can interlock and pop to assemble and disassemble all over again. The best part is that all showpieces look great while displayed in these display units since their silver finish is spectacular.

How is it made?

Have you ever wondered how this complex but extremely useful product is made? The full step-wise process of aluminum extrusion is explained below for your convenience.

  1. Preparation of the Die – You will need the tube to get the round toothpaste out. Similarly, the die is your mold to get the cross-sectional shape of the metal you require. Consequently, an H13 steel die is prepared or ordered from a warehouse and preheated for use.
  2. The billet is preheated and transferred – A billet is made from aluminum-shaped cylindrically. Before loading into the extrusion press, it is preheated at 400 and 500 degrees temperature. It makes it just ready enough for the molding but not enough to melt. A lubricant is applied, and the billet is transferred into the press.
  3. The ram pressurizes the billet – Now, the hot and extremely malleable billet is pressurized by the hydraulic ram with 15000 tons of weight. This forces the billet to fit inside the container and take its shape.
  4. The Die – Next, the continual pressure pushes the content material into the die and takes its shape. The ram keeps pushing the weight until the billet has fully molded to the die’s dimensions. It comes out through the opening as the desired profile.
  5. Puller and cooling – The profile comes out from the opening. It is handled by a puller running at a matching speed to guide it on the runway or runout table. Water and fans on this runway are used to cool the profile even. This process is also known as quenching.
  6. Cutting – Now that the profile has exited onto the table, it must be sheared according to the table length. Despite the quenching, a temperature-controlled saw is used to cut through the still-hot profiles.
  7. Cooling – Now, the transfer takes place from the runout table to the cooling station. All profiles will remain here until they reach room temperature. This is crucial for the next step of extending and shaping to occur.
  8. Straightening and shaping – Even though the process described above is thorough, some natural twisting occurs that aligns the profiles out of shape. The profiles are moved to a stretching station, where they are pulled from both sides by machine hands to tackle this problem. This results in completely linear profiles.
  9. Sawing – On this station, the profiles are sawed according to the industrial dimensions required for sale. This can be anywhere from 7ft to 22ft.
  10. Tempering – This whole process has led to making profiles that are T4 in temper. According to the market requirement, they are moved to the oven and brought to T5 or T6 tempers.
  11. Enhancement through heating- The T4 profiles have a tensile strength of approximately 240MPa. They can be heat-treated in the oven to increase their overall yield stress and strength. This leads to the more load-bearing capacity of the metal. It can further be used to produce more heavy-duty equipment or construction. For instance, heating to achieve the T6 temper means achieving the tensile strength of 310 Mpa.
  12. Finishing – These profiles are famous for their stunning appearance. It’s due to their ability to be open to options of painting and sublimation. However, all this is only possible after anodizing has taken place. Anodizing involves enhancing the already present oxide layer on the profiles. This makes them weather-proof and rust-resistant. After this step, you’re free to style your metal as you please!
  13. Final detailing – This consists of any drilling or grooving that your product requires. Any kind of accessories or screws and bolts can now be adjusted in this final step.

Why is it called 80/20?

The 80/20 name has become an example of genericization like Hoover or Kleenex. They have become the namesake of the product they endorse. The originating manufacturer of aluminum extrusion was called 80/20 Inc. But why this name was chosen involves an interesting tale that dates back to the 19th century.

The 80/20 rule is also known as the Pareto principle. The work of Vilfredo Pareto inspired it. Pareto was an engineer and philosopher from Italy. He devised the ‘law of the vital few,’ which stated that 80% of the land in Italy was owned by 20% of the population.

Soon enough, this law caught on in many fields. To observe a simple example, the top 20% of earners pay 80% of the income tax. In business, it was seen that 80% of the company’s results are directly a cause of 20% of its efforts.

Now isn’t that an interesting bit of trivia?

Are aluminum extrusions strong?

They are extremely popular for their variety of cross-sectional shapes. The alloy’s strength made its popularity blow over if seen in terms of tensile strength. It is a unit dedicated to assessing the amount of load a material can take before it breaks. Aluminum rates highly.

6063 is the most common alloy used for extrusion, and its tensile strength ranges from 145-186 Mpa. The top-level temper of 6063-T6 has a high tensile strength of 190MPA.

But even with this capacity, it remains lightweight. This is evident when you note that aluminum with 276MPA strength has a density of merely 2.81gcm-3. It becomes the primary factor in its outdoor structural framework and an integral part of heavy-duty construction machinery.
