In the aluminum extruding process, applied pressure provided by a ram forces heated aluminum billets through a die to form aluminum extrusions in different shapes. This extruding process can produce a variety of shapes like rods, complex cross-sections, hollow sections and tubes at very close tolerances. Aluminum extrusions can range from millimeter parts weighing ounces to parts that are meters in length weighing considerably more.
Because of the inherent properties and versatility of aluminum, there are advantages in using aluminum extrusions over other materials in product designs. Some of these are that aluminum is abundant so therefore cost-effective, has a high strength- to -weight ratio and high electrical conductivity, a good heat conductor and can be extruded into complex shapes. In addition, aluminum extrusion producers can provide aluminum components for many applications and to diverse industries without having to melt down and cast the metal.
Some parameters to consider when searching for aluminum extrusion suppliers are:
1. Review carefully the design considerations for your project when creating aluminum extrusions.
2. Look for aluminum extrusions manufacturers that provide multiple services.
3. Select the right aluminum extrusion company for custom or specialty extrusion products.
Action Steps
The best contacts and resources to help you get it done
Determine the best alloy for your aluminum extrusion project
A critical design element for an aluminum extrusion project is choosing the right alloy. Finding companies that can meet your design needs, knowing about extruded aluminum alloys by series and looking at factors like alloy strength and finish are also important. The best solution is to get this information online from resources that can help you choose the right design specifications for a project and the companies that can meet them.
I recommend: The
Aluminum Extruders Council is a trade association that offers directories in which you can find extrusion suppliers, producers and buyers’ guide. It also offers technical information like material comparison charts, alloy designation and much more. At
Engineering Fundamentals, you can find the mechanical properties and description of different aluminum alloys by category.
Find an aluminum extrusion company that can meet all your project needs
When looking for extrusion services, find out about the different services that each company provides. You may need services that include design assistance, fabrication, and machining or having certification requirements. Choose a company that has multiple services all under one roof to meet all your needs.
I recommend: Mid-States Aluminum Corp. is a one-stop solution for aluminum extrusions. The company offers many services that include engineering support, anodizing and finishing.
Aluminum Extruded Shapes and
Aerolite Extrusions Co. are other full service aluminum extrusions distributors that offer channels, tubing and other shapes.
Futura Industries can provide a full range of extruded profiles from large to thin- walled ones. There are many other services provided like fabrication, anodizing and no minimum quantity is required.
Get a custom or specialty product from aluminum extrusion companies for a unique or complex applicat
Many times, a standard product may not meet your all design requirements. If you need a very small, complex or custom extrusion then pick an aluminum extrusion manufacturer that has the experience to deliver cost effective custom products.
I recommend: Custom Aluminum Products, Inc. can provide custom extrusion profiles in different sizes ranging from 7 to 10 in circle sizes and complex shapes. The company also has many other services available. At
Mann Made Inc., you can find miniature extrusions in exacting tolerances, different aluminum alloy series and cross sectional areas as low as .002 inches.
American Douglas Metals Inc. also offers custom extrusions in various finishes.
Tips & Tactics
Helpful advice for making the most of this Guide
- For aluminum extrusions, you should select the best cost effective packaging method for your type of product. This depends on the finish grade of the material to be shipped. Ask about the types of packaging methods provided by a company.
