To meet a standard tolerance, aluminum extrusions must be produced with dimensions accurate within hundreths or thousandths of an inch. The figures below are broad generalizations. Twist 0.5 deg. The designer should carefully consider the requirements of the application and specify special tolerances only where they are really needed. The design properties of aluminum extrusions are many.
Extruded aluminum can be a vital part of any project, no matter the industry or application.
While competing materials may offer a few of the advantages of aluminum extrusions, none can offer them all at the same time. Following is a list of the many advantageous properties of aluminum. Compared to competing materials like steel and copper, aluminum is lightweight yet extremely strong. Resilient Extruded aluminum profiles can deflect under loads and shocks and still spring back, for those projects and applications that require flexible strength. Thermally conductive Aluminum conducts heat better than any other common metal, and excels in cooling applications as well.
