Aluminum Extrusion

Aluminum Extrusion

Tolerancing, General Rules: 

  • Linear Cross Section or Profile Dimensions: ± 0.008" per inch of the dimension. 
  • Wall Thickness: ± 10% of the specified dimension. 
  • Twist: ½ degree per foot of length 
  • Straightness: 0.0125" per foot of length. 
  • Flatness: 0.004” per foot 
  • Angularity: Will vary with wall thickness and size of the surface but are generally between ±1 degree and ±2 degrees. 

More specific industry standard tolerancing can be found in The Aluminum Extrusion Manual published by the Aluminum Association Incorporated and the Aluminum Extruders Council. 

Affordable

Cost effective material and less expensive than other metal forming processes for long linear shapes, especially hollow profiles.

Corrosion Resistant

Properly alloyed aluminum does not rust. Its exposed surface combines with oxygen to form an inert aluminum oxide film which further blocks oxidation.  

Lightweight

Appropriately alloyed and treated, aluminum can be as strong as some steels with minimum yield strengths as high as 76,000 psi. Can also be made with lower strength where product specifications call for it.

Linear Extrusion Process Overview

Linear extruding is the process of shaping material starting in the form of a billet or slug and forcing it to flow through a shaped opening in a die with the use of a ram. Extruded material emerges as an elongated piece with the same profile as the die opening. There are two types of extrusion processes, direct and indirect. Direct extrusion is a process in which the die head is held stationary, and a moving ram forces the metal through it. Indirect extrusion is a process in which the billet remains stationary while the die assembly is on the end of the ram and moves against the billet, creating pressure needed for metal to flow through the die. 

  • Strength

    Appropriately alloyed and treated, aluminum can be as strong as some steels with minimum yield strengths as high as 76,000 psi. Can also be made with lower strength where product specifications call for it.

  • Resilient

    Can deflect under loads and shock and spring right backCan be designed as a product function wherever functional strength is valued.
