ALLOY AA 1100, TEMPER H-14 is a commercially pure aluminum material known for its excellent formability, corrosion resistance, thermal conductivity, and electrical conductivity. It is one of the most widely used 1xxx series aluminum alloys for sheet, coil, strip, and fabricated components.
Compared with softer 1100-O aluminum, AA 1100-H14 has been strain hardened to provide higher strength while keeping good forming performance. This makes aluminum 1100 H14 a practical choice for general fabrication, heat transfer equipment, roofing products, kitchen equipment, nameplates, and many industrial applications.
This guide explains the aluminium alloy 1100 datasheet, aluminium 1100 chemical composition, aluminum 1100 properties, mechanical properties, H14 temper meaning, hardness, and the differences between aluminum 1100 vs 6061 and aluminum 1100 vs 5052.
1. What Is 1100 Aluminum Alloy?
AA 1100 is a commercially pure aluminum alloy in the 1xxx series. Aluminum makes up at least 99.00% of the alloy, while small amounts of copper, iron, silicon, manganese, zinc, and other elements are controlled to provide the required material characteristics.
The main advantage of aluminum 1100 is its balance of low strength and excellent workability. It is easy to roll, bend, stamp, draw, and form. It also provides good resistance to atmospheric corrosion and has high thermal and electrical conductivity.
The alloy can be supplied in different tempers. For buyers looking for a stronger sheet while still requiring good fabrication performance, ALLOY AA 1100, TEMPER H-14 is one of the most common specifications.
Property | AA 1100-H14 | Typical Characteristics |
Alloy series | 1xxx | Commercially pure aluminum |
Temper | H14 | Strain hardened, half hard |
Density | About 2.71 g/cm³ | Lightweight material |
Corrosion resistance | Excellent | Suitable for many atmospheric environments |
Formability | Very good | Suitable for bending, stamping and general fabrication |
2. What Are the Properties of AA 1100 H14 Aluminum?
The main aluminum 1100 properties come from its high aluminum purity. AA 1100 offers excellent corrosion resistance, good formability, high thermal conductivity, and high electrical conductivity. These properties make it useful when extreme strength is not the main design requirement.
Excellent formability
Aluminum 1100 is one of the easiest commercial aluminum alloys to form. H14 provides more strength than the fully annealed condition but still retains useful ductility. It can be bent, roll formed, stamped, and fabricated for many sheet metal applications.
Good corrosion resistance
The high aluminum content allows a protective oxide film to form naturally on the surface. This provides good resistance to atmospheric corrosion and makes AA 1100 suitable for many indoor and outdoor applications.
High thermal and electrical conductivity
Aluminum 1100 has high thermal conductivity and electrical conductivity compared with many alloyed aluminum grades. This is why 1100 aluminum is frequently selected for heat transfer components, electrical applications, cooking equipment, and industrial heat shields.
Easy welding and fabrication
AA 1100 can be welded using common aluminum welding processes. It is also easy to cut, machine, drill, and fabricate. For production lines that value simple processing and consistent surface quality, aluminum 1100 H14 remains a practical material choice.
3. What Is the Aluminium 1100 Chemical Composition?
The aluminium 1100 chemical composition is mainly aluminum. Unlike 5xxx and 6xxx series alloys, AA 1100 does not depend on large additions of magnesium or silicon for strength. Its performance is largely based on high aluminum purity and the selected temper.
Element | Typical / Maximum Content | Function |
Aluminum (Al) | 99.00% minimum | Base metal and main source of conductivity and corrosion resistance |
Cu | 0.05–0.20% | Minor alloying element |
Fe + Si | Up to about 0.95% combined | Controlled impurities |
Mn | 0.05% max | Controlled minor element |
Zn | 0.10% max | Controlled impurity |
Note: Exact limits can vary slightly by product form and applicable standard. Buyers should confirm the required standard and mill certificate before ordering.
4. What Does H14 Mean in Aluminum?
H14 is a temper designation. In aluminum temper terminology, the letter H means the alloy has been strain hardened. The number 1 indicates strain hardened only, while the final number 4 indicates a half-hard condition.
Therefore, aluminum 1100 H14 means AA 1100 has been cold worked to achieve a controlled strength level without heat treatment. It is harder and stronger than 1100-O, but it remains more formable than fully hard tempers.
Temper | Condition | Typical Use |
O | Annealed | Maximum formability and deep forming |
H14 | Strain hardened, half hard | General sheet metal fabrication, roofing, panels and industrial parts |
H18 | Strain hardened, full hard | Applications requiring higher strength and lower ductility |
For buyers who need a balance between strength and fabrication, H14 is often a more practical choice than the softer O temper or harder H18 temper.
5. What Are the Mechanical Properties of Aluminum 1100 H14?
The aluminum 1100 mechanical properties depend on product thickness and the applicable material standard. Typical values for AA 1100 H14 sheet are shown below as a practical reference for material selection.
Mechanical Property | Typical AA 1100-H14 | Unit |
Tensile strength | 110–145 | MPa |
Yield strength | 95–125 | MPa |
Elongation | Approximately 4–10 | % |
Elastic modulus | About 69 | GPa |
Density | 2.71 | g/cm³ |
Actual mechanical values should always be confirmed against the specified ASTM, EN, JIS, or other applicable standard and the supplier's mill test certificate.
6. What Is the Hardness of Aluminum 1100 H14?
Aluminum 1100 is a relatively soft aluminum alloy. In H14 temper, its hardness increases because of cold working. Typical hardness is around 32–40 HB on the Brinell scale, although the exact value varies with thickness, processing route, and testing method.
This hardness level is useful for sheet metal fabrication because the material has enough strength for many general-purpose applications without becoming difficult to bend or form. If a project requires much higher hardness and strength, an alloy such as 6061-T6 may be a better choice.
7. Aluminum 1100 vs 6061: Which Alloy Should You Choose?
Aluminum 1100 and 6061 serve different purposes. AA 1100 is a commercially pure aluminum alloy designed mainly for formability, corrosion resistance, and conductivity. 6061 is a heat-treatable structural alloy designed for higher strength.
Property | 1100-H14 | 6061-T6 | Typical Choice |
Strength | Low to moderate | High | Choose 6061 when structural strength is critical |
Formability | Excellent | Moderate in T6 | Choose 1100 for easier forming |
Conductivity | Excellent | Lower | 1100 is preferred for conductivity-focused applications |
Machinability | Fair | Good | 6061 is usually better for machined structural parts |
In simple terms, choose 1100-H14 when formability, corrosion resistance, and conductivity are more important than high structural strength. Choose 6061 when strength and machining performance are the priority.
8. Aluminum 1100 vs 5052: What Is the Difference?
The main difference between aluminum 1100 and 5052 is strength. 5052 is an aluminum-magnesium alloy and normally provides much higher strength than 1100-H14. However, 1100 offers higher aluminum purity and excellent thermal and electrical conductivity.
Factor | 1100-H14 | 5052-H32 | Better Choice |
Strength | Lower | Higher | 5052 |
Formability | Excellent | Very good | 1100 for easier forming |
Conductivity | Very high | Lower | 1100 |
Marine use | Limited | Better | 5052 |
For general sheet fabrication and conductivity applications, 1100-H14 is often economical and easy to process. For marine components, transportation parts, fuel tanks, and applications requiring higher strength, 5052 is generally more suitable.
9. Applications of Aluminum 1100 H14
Because of its combination of formability, corrosion resistance, conductivity, and relatively low cost, aluminum 1100 H14 is used across many industries.
Industry | Application | Why 1100-H14 |
Heat transfer | Heat exchangers and heat shields | High thermal conductivity |
Kitchen equipment | Utensils, cookware components | Easy forming and good thermal performance |
Building | Roofing, flashing and panels | Light weight and corrosion resistance |
