Overview of 1100 Aluminum Sheet
1100 aluminum is a commercially pure, non-heat-treatable alloy with a minimum aluminum content of 99.0%. It is the most commercially pure of all aluminum alloys and is considered a ‘workhorse’ for general-purpose fabrication. 1100 aluminum is best known for its superior ductility, excellent formability, outstanding corrosion resistance, and high thermal and electrical conductivity. While it is a very low-strength alloy, its other properties make it the ideal choice for applications involving intricate forming, deep drawing, or where excellent corrosion resistance is paramount. It is specified under standards like ASTM B209 and EN 573 (as EN AW-1100).
Key Features and Properties of 1100 Aluminum
The characteristics of 1100 aluminum stem directly from its high purity:
– **Superb Formability:** In its annealed state (O temper), it is extremely soft and ductile, making it the best aluminum alloy for deep drawing, spinning, and complex bending operations.
– **Excellent Corrosion Resistance:** It has outstanding resistance to weathering and a wide range of chemicals, making it suitable for chemical equipment and food handling.
– **High Thermal & Electrical Conductivity:** Its conductivity is among the highest of all aluminum alloys, making it an excellent material for heat exchanger fins and electrical components.
– **Excellent Weldability:** 1100 aluminum is readily weldable using all conventional methods, particularly TIG and MIG, producing strong and reliable joints.
– **Low Strength:** It has the lowest strength of all commercial aluminum grades. Its strength can only be increased via strain hardening (cold working) to tempers like H14 or H18.
Main Applications of 1100 Aluminum Sheet
The exceptional formability of 1100 aluminum makes it a top choice for a variety of applications:
– **Sheet Metal Work:** Used for general fabrication, flashing, architectural trim, and ductwork.
– **Chemical & Food Industries:** Ideal for manufacturing chemical storage equipment, food processing equipment, and aluminum foil for packaging.
– **Heat Exchangers:** Widely used for fins on heat exchangers in air conditioning units and refrigerators.
– **Lighting & Decorative:** Its ability to be finished to a bright, reflective surface makes it perfect for light reflectors, nameplates, and decorative parts.
– **Spun Hollowware:** The preferred material for producing spun items like bowls, utensils, and kitchenware.

❓ Frequently Asked Questions
What is 1100 aluminum?
1100 aluminum is a commercially pure aluminum alloy with a minimum aluminum content of 99.0%. It is a soft, ductile, low-strength alloy known for its excellent formability, corrosion resistance, and high electrical and thermal conductivity.
What is 1100 aluminum used for?
It is used for applications where formability is key and strength is not a major concern. Common uses include deep-drawn parts, spun hollowware, heat exchanger fins, chemical equipment, food handling equipment, and general sheet metal work.
What is the difference between 1100 and 3003 aluminum?
The main difference is strength. 3003 contains added manganese, making it about 20% stronger than 1100. In exchange for this added strength, 3003 has slightly lower formability than 1100. 1100 is chosen for the most demanding forming operations.
Is 1100 aluminum heat-treatable?
No, 1100 is a non-heat-treatable alloy. The only way to increase its strength is through cold working, which results in tempers like H14 (half-hard) and H18 (full-hard).
What do H14 and H18 tempers mean?
These tempers indicate the degree of strain hardening (cold work). H14 is half-hard, offering a balance between increased strength and some remaining formability. H18 is full-hard, providing the highest strength for this alloy but with very limited formability.
