3.What is Aluminum Extrusion?
Aluminum extrusion is a technique used to transform aluminum alloy into objects with a definitive cross-sectional profile for a wide range of uses. The extrusion process makes the most of aluminum’s unique combination of physical characteristics. Its malleability allows it to be easily machined and cast, and yet aluminum is one third the density and stiffness of steel so the resulting products offer strength and stability, particularly when alloyed with other metals.
4.The Process of Aluminum Extrusion in 5 Steps
Aluminum extrusion is the process of forcing heated raw aluminum (billet) through a pre-designed set of dies using pressure and heat. A ram applies the pressure. This process is similar to a hot glue gun. The raw aluminum (billet) comes in a cylindrical shape that is usually around 20 feet long with a varying diameter that depends on the custom aluminum extrusion manufacturer requirements. Below are the basic steps from beginning to end.
The billet is cut to the desired length based on the product specifications. The billet is then moved to a tunnel heater that heats the billet to about 900 degrees Fahrenheit. The exact temperature is based on what the make-up of the aluminum is.
After heating, the billet is coated with a lubricant to prevent sticking. It is then placed into a cradle. A set of dies that match the customer specification are placed in line. The billet is forced through these dies using a ram and anywhere from 1600 to 6000 tons of pressure. Maintaining a consistent temperature is key through this process.
The extruded pieces are then cooled for the stretching process. Cooling methods vary depending on the manufacturer. Air, water or both achieve cooling. This is key for the stretching process.
-STRETCHING AND CUTTING
A gripper on both ends of the extruded pieces stretch the piece to ensure it is straight and then the stretched pieces are cut to customer lengths.
The pieces are then aged. They are heated up to about 350 degrees Fahrenheit for a minimum of four hours to harden the aluminum.
5. Advantages of Aluminum Extrusion
Growing up, most of us were taught not to do something just because everyone else was doing it. That piece of parental advice doesn’t really apply to design work though. When so many designers are using extrusion it’s worth asking why. Here are eight of the biggest reasons.
1). Easy to work
Most grades of aluminum machine easily. You can cut aluminum extrusion to length with a hacksaw and drill holes with your cordless DeWALT. If you’re designing a frame or display and don’t know exactly where the mounting holes should go, leave it to the installation crew!
At about 1/3rd the density of steel, aluminum is an excellent choice in any motion-related application. Less weight means less inertia, which translates to energy savings and higher speeds. And the benefit of extruded section is that it puts material only where it’s needed, potentially reducing weight further.
3). Inexpensive tooling
When designers think about using extruded aluminum they’ll often restrict themselves to the shapes available in catalogs of standard products. That can be a missed opportunity for design optimization, and it’s a pity because tooling for custom extrusion is surprisingly inexpensive.
Extruded aluminum can be painted, plated, polished and even textured. And let’s not overlook anodizing. This gives the designer a broader pallet of finishes to choose from than is possible with other materials.
5). Won’t corrode
Like iron, aluminum loves oxygen, but with a big difference. Iron oxide – rust – flakes away but aluminum oxide just forms a protective film over the surface. That can save on the expense of coating processes and eliminates maintenance.
6). Reuse and recycle
If you’ve ever been drawn into a can collection drive you’ll know there’s a market for scrap aluminum. That means when your product reaches the end of it’s life there are no disposal headaches. In fact quite the opposite: it will have some value. Don’t overlook either the option of just disassembling a product made from extruded section and putting the pieces to work in a different way.
7). Surprisingly strong
Aluminum has a higher strength-to-weight ratio than many other materials. For example, 6061-T6 grade aluminum is nearly four times the strength of 304 stainless, and extrusion maximizes stiffness while minimizing weight. That makes it a good choice in load-bearing applications – like aircraft!
8). Eliminates welding
Making consistently good welds takes skill and experience, plus you’ll often need fixtures and may have to sacrifice some pieces for practice. In contrast, a single piece of aluminum extrusion can replace multiple separate pieces that would otherwise be welded together. If you’re really clever you’ll even design sections that interlock for easy assembly!

--Aluminum Alloys: 1060 Alloy/ 3003 Alloy/ 6042 Alloy / 6061 Alloy / 6063 Alloy / 6262 Alloy etc.
7. Application Industries
Today, aluminum extrusion is used for a wide range of purposes, including components of the International Space Station. These diverse applications are possible due to the advantageous attributes of aluminum, from its particular blend of strength and ductility to its conductivity, its non-magnetic properties and its ability to be recycled repeatedly without loss of integrity. All of these capabilities make aluminum extrusion a viable and adaptable solution for an growing number of manufacturing needs.
