General Info About 6063 Aluminum Tube

Due to good corrosion resistance, weldability, and excellent surface finishing characteristics, 6063 is one of the most common alloys in the 6000 aluminum series.

More Details About 6063 Aluminum Tube

  • Advantages/Disadvantages

    6063 aluminum tube has good corrosion resistance, good weldability and excellent finishing characteristics. Another advantage is that the tube can be both hot and cold-finished. Though it has fair machinability, this grade can be easily formed and anodized.

  • Industries

    This grade is common in a wide range of industries, including the construction, architectural, building products, home goods, irrigation, appliance, marine, aerospace, and automotive industries.

  • Applications

    It is used in electrical systems, pipe railings, anodized parts, door frames, railroad transportation, architecture, irrigation tubing, and automotive parts.

  • Machining

    It has fair machinability.

  • Welding

    It has good weldability.

  • Heat Treatment

    It is heat treatable.

Frequently Asked Questions

  • What is the difference between 6061 and 6063 aluminum?


    Strength is the main difference between these two common alloys. They have excellent corrosion resistance and finishing quality. They are both lightweight, easily anodized, and good for extrusion. However, where strength is a critical factor, 6061 is recommended over 6063, which is better described as a medium strength alloy.

  • Which 6063 temper is better for bending?


    When bending is a significant fabrication consideration, and both 6063-T5 and 6063-T6 are available, T5 is recommended.
