Aluminum extrusion is a process by which aluminum is turned into a variety of different shapes with the purpose of the aluminum becoming part of a cross-section profile. In its creation, the aluminum is pushed through a die, which allows the producer to create complex cross-sections while strengthening the metal. There are numerous benefits involved with purchasing extruded aluminum shapes from reduced manufacturing costs, to reduced purchased part weight. If you are working a reputable metal supply company, they will have the experience to guide you through the process, and educate you on the benefits of a custom extrusion option.
Easily Accessible
One of the main benefits of aluminum extrusions is how accessible the material is. Aluminum is one of the most commonly mined materials on Earth and there is no shortage upcoming, making it easy to find aluminum suppliers. In your search, you will find a number of different aluminum extrusion suppliers, so it is vital that you do your research to find the vendors that best meets your needs. These vendors should provide you with great customer service, have a deep rooted knowledge of the extrusion process, and have the ability to process and inventory your custom aluminum extrusions as needed.
Different Shapes
Another thing to consider is the extensive number of extruded aluminum shapes that can be created by your vendor. The complexity of possible shapes that can be extruded is amazing. Sometimes the shapes have very light gauge walls and irregular surfaces, making these shapes difficult to cut. Be sure that you are working with an aluminum supplier that is experienced in cutting custom extrusions, one with the proper precision sawing equipment to make cuts to very precise tolerances. The highest quality metal service centers will be able to cut hundreds or thousands of parts consistently to a +/- .005 tolerance. Lastly, if you are comparing an aluminum casting to an aluminum extrusion, the casting might weigh less, but you will be sacrificing strength. In addition aluminum extrusions do not have the long lead times and high tooling costs that you will find in castings.
Long Life
Perhaps the most important benefit provided by aluminum extrusion is that the finished product will stand the test of time. When many people think of aluminum, they envision a soda can that is crushed without any effort whatsoever. The truth is that aluminum is actually a very durable, although sometimes soft, aluminum takes a very long time to break down. Once you have your extrusions in place, they will serve their purpose for a long period of time without the need for replacement.
