General Info About 1100 Aluminum Sheet

1100 aluminum, known as commercially pure aluminum, is the softest aluminum available. It has an excellent host of benefits and is a good use for many applications spanning several industries.

More Details About 1100 Aluminum

  • Advantages/Disadvantages

    This alloy is part of the softest aluminum alloys but has excellent corrosion resistance and workability. It has high electrical conductivity and the highest thermal conductivity. Due to its softness, it is not used for high-strength or high-pressure applications.

  • Industries

    1100 aluminum sheet is most common in the chemical and food and beverage  industries.

  • Applications

    It has excellent corrosion resistance and is therefore often used in chemical equipment, name plates, cooking utensils, decorative trim, and sheet metal.

  • Machining

    It has excellent machinability, especially when it’s machined in hard temper.

  • Welding

    This aluminum grade demonstrates good weldability.

  • Workability

    Among a host of benefits, its excellent workability makes it a good fit for applications requiring advanced forming. This aluminum grade can be formed into many different shapes and forms through cold working.

  • Heat Treatment

    It is not heat treatable.

Frequently Asked Questions

  • What is 1100 aluminum used for?


    Aluminum 1100 can be shaped into many different products and most frequently appears in railroad tank cars, fin stock, dials, cooking utensils, name plans, chemical equipment, dials, and more. The plumbing and lighting industries also make frequent use of 1100 aluminum sheet, in addition to many other industries.

  • What is 1100 h14 aluminum?


    1100 aluminum is actually commercially pure aluminum, meaning it has 99.00% purity at a minimum. This gives it many of its benefits, including excellent corrosion resistance, workability, and weldability, in addition to high thermal conductivity.

  • What is the difference between 1100 and 3003 aluminum?


    The main difference is that 3003 aluminum gets a 20% boost in strength over 1100 grade aluminum because of the addition of Manganese and Copper. While that seems like a lot, 3003 aluminum is still considered to have only moderate strength compared to other alloys.

  • What is the softest grade of aluminum?


    1100 aluminum is the softest grade of aluminum. It is soft and ductile and has excellent workability, making it ideal for applications with difficult forming. It can be welded using any method, but it is non heat-treatable
