Aluminum Extrusion Profiles

At Whitehall Industries, we provide precision aluminum extrusions to diverse industries such as business machines, medical products, and consumer goods. Our engineers and skilled technicians work in tandem using cutting edge technology to deliver custom and near net profile shape precision extrusions of solids, semi-hollows and hollow profiles. Using aluminum and alloys in the 1000, 3000, 6000 and 7000 series, our presses have capacity between 2000 and 2700 tons allowing a maximum circumscribing circle size of 7" to 8" for any extrusion. All extrusions achieve precision tolerances of ±0.1 mm dimensional, ±0.25 mm for feature location, ±0.05 mm for inside diameter, and ±0.15mm for concentricity. Upon exiting the presses, extrusions move to fully automated handling and stretching systems followed by air and water quench to achieve tempers of T1, T4, T5 or T6 depending on the alloy.

Another differentiator we offer from the competition is our ability to reach surface finishes of 6.5 Ra-which is 30% better than the industry standard of 32 Ra. We have the ability to manufacture in volume from early prototype development up to full production up to three million units annually, with typical lead times of four to six weeks.
