Types of Extruded Aluminum Alloys

Aluminum Alloy 6063

The most economical and widely used, 6063 has superior extrudability. With very good corrosion resistance and finishing response, it also is readily welded, machined, and formed. Examples of the many applications that utilize 6063 aluminum alloy include:

  • Architecture and construction products
  • Window and door frames
  • Electrical tubing
  • Irrigation system pipe and tube
  • Handrails and furniture
  • Awnings
  • Trims and thresholds
  • Cleanroom Filtration

Aluminum Alloy 6463

Since 6463 is roughly 98% raw aluminum, heat-treating increases the strength of the aluminum while lowering the ductility. It can be polished to a mirror-like finish and is primarily used for decorative trim. Examples of the many applications that utilize 6463 aluminum alloy include:

  • Boating
  • All-Terrain Vehicles
  • Picture frames
  • Shower Doors
  • High-End Cosmetic Shelving

Aluminum Alloy 6005

When high corrosion resistance and moderate strength is required, 6005 aluminum alloy is preferred. It has excellent extrudability and is classified as a more structural alloy that finishes well. It is similar to 6063 but finishes more consistently and at better quality. It can be easily formed, machined, and welded. Examples of the many applications that utilize 6005 aluminum alloy include:

  • Ladders
  • Automotive applications
  • Curtain wall
  • Bullet Resistant Storefronts
  • Composite Wall Systems

Aluminum Alloy 6061

6061 has superb strength, corrosion resistance, and machinability. It has good formability and weldability but does not respond well to finishing. For that reason, it is typically used in transportation and structural applications. Examples of the many applications that utilize 6061 aluminum alloy include:

  • Aerospace
  • Automotive
  • Machining
  • Marine Applications
  • Transportation
  • Utility trailers
