Aluminum Extrusion Machining Service

At DEK, 6061 aluminum is one of the most versatile choices for aluminum extrusion machining. It offers an excellent balance of strength, corrosion resistance rating of 8/10, and machinability score of 90%, making it suitable for structural frames, machine components, and transportation parts.

Our process ensures tight tolerances and smooth finishes, allowing complex profiles to be integrated directly into assemblies. With its excellent anodizing response, 6061 extrusions can be tailored for both durability and appearance. Typical projects include precision machine frames, conveyor system rails, and custom heat sink housings for aerospace, automotive, electronics, and general engineering applications.

DEK frequently uses 6063 aluminum alloy for extrusion machining when high-quality surface finish and corrosion resistance are priorities. Known as the “architectural alloy,” it features a tensile strength of 190 MPa, a corrosion resistance rating of 9/10, and a machinability score of 80%. ideal for window frames, door frames, enclosures, and decorative trims.

Our precision machining processes integrate slots, grooves, and mounting features directly into the extrusion, reducing secondary work. With excellent anodizing properties, 6063 supports aesthetic and functional coatings for outdoor and architectural use. Applications include architectural curtain wall frames, decorative panel trims, and precision instrument enclosures.

In DEK’s aluminum extrusion machining, 6082 is the alloy of choice for demanding structural and load-bearing applications. Known for its high strength with tensile strength of 340 MPa and excellent machinability, it is well-suited to cranes, bridges, transport structures, and offshore platforms.

DEK’s machining capabilities create complex shapes and precision joints directly into extruded profiles, enhancing assembly efficiency. With strong corrosion resistance and weldability, 6082 is ideal for both indoor and outdoor applications such as heavy-duty support beams, transport vehicle chassis rails, and offshore walkway frames.

DEK uses 7075 aluminum alloy in extrusion machining when maximum strength is required without sacrificing precision. This high-strength alloy offers excellent fatigue resistance, making it ideal for aerospace components, defense hardware, and high-performance sporting equipment.

Our advanced CNC processes machine detailed geometries into 7075 extrusions with minimal deviation, maintaining tight tolerances. Although less corrosion-resistant than some alloys, DEK applies protective surface treatments to extend service life. Common uses include aerospace landing gear struts, precision firearm receiver housings, and performance bicycle frame members.

In DEK’s aluminum extrusion machining, 2024 is valued for its superior fatigue resistance and high strength, making it ideal for aerospace and motorsport applications. It performs exceptionally well in parts subjected to repeated stress, such as wing structures, fuselage components, and racing chassis elements.

Our extrusion and precision machining processes allow complex features to be integrated seamlessly. While 2024 has limited corrosion resistance, DEK applies coatings like anodizing or plating to ensure durability. It is often used for aircraft fuselage stiffeners, racing car suspension arms, and helicopter rotor hub components.

DEK works with 5052 aluminum alloy for extrusion machining projects requiring excellent corrosion resistance with a rating of 9/10, especially in marine and coastal environments. Its superior formability and weldability make it a strong choice for boat components, fuel tanks, enclosures, and food processing equipment.

DEK’s machining process incorporates precise holes, slots, and cutouts into extruded profiles, ensuring components are ready for immediate assembly. Typical applications include marine deck railings, refrigerated truck body panels, and food-grade processing enclosures.

DEK’s aluminum extrusion machining with 5083 alloy serves industries requiring extreme corrosion resistance with a rating of 10/10 and high strength with 317 MPa, such as marine, cryogenics, and defense sectors. Known for its performance in challenging environments, 5083 maintains structural integrity even under prolonged exposure to seawater or low temperatures.

Our machining process enables intricate detailing in extrusions while preserving mechanical properties. It is widely used in ship hull reinforcement beams, cryogenic storage vessel frames, and military vehicle armor panels.
