1100 H26 Aluminum

1100 H26 aluminum alloy is commonly used in applications that require high strength, good corrosion resistance, and moderate ductility. It belongs to the 1100 series of aluminum alloys, which are known for their excellent corrosion resistance, good workability, and very high ductility. Specifically, the 1100 H26 version of aluminum alloy is treated to combine strength and formability, making it widely used in fields that require good formability and corrosion resistance.

1100 H26 Aluminum Properties

Property	Description
Hardness	The H26 state of aluminum alloy has relatively high hardness. Although its hardness is lower than the H28 state, it still provides sufficient strength to withstand certain mechanical pressures. Compared to the H22 and H24 states, H26 has a higher hardness, but it does not have the maximum hardness, making it suitable for applications that require higher strength but do not need extreme hardness.
Ductility	Compared to other states of 1100 aluminum, the H26 state has lower ductility, ranking second. Ductility refers to the material's ability to deform under external force. Although its ductility is lower, it still meets certain forming requirements but may have limitations in extremely complex forming processes. This alloy is suitable for applications that require shape retention but has weaker deformation ability compared to H22 and H24 states.
Workability	1100 H26 aluminum alloy has a certain degree of workability. Due to its work hardening characteristics, although its ductility is lower, the alloy can be processed into different forms through cold working, deep drawing, and other methods, especially suitable for stamping, curling, and stretching thin sheets. Due to the higher hardness of H26, more processing force may be required during forming, but it is still suitable for various light-load mechanical processing applications.
Corrosion Resistance	1100 H26 aluminum alloy has excellent corrosion resistance, especially suitable for environments that require oxidation and corrosion resistance, such as marine environments, chemical environments, etc. This alloy can remain corrosion-resistant for a long time in natural environments and is ideal for equipment and components exposed to moisture, salt spray, or chemicals. Its outstanding corrosion resistance makes it an ideal material for many industrial and construction applications.
Surface Treatment	1100 H26 aluminum alloy can further enhance its corrosion resistance and extend its service life through surface treatments such as anodizing and spraying. Although it already has strong corrosion resistance in its natural state, surface treatment can improve its appearance, wear resistance, and ability to withstand environmental impacts. Anodizing can form a protective film on its surface, further enhancing its rust resistance, making it especially suitable for use in harsh environments.

Due to its hardness, corrosion resistance, and certain workability, this aluminum alloy is suitable for applications in chemical equipment, marine structures, decorative materials, and other applications requiring oxidation resistance and strength.

1100 H26 Aluminum Mechanical Properties

Tensile Strength: The tensile strength of 1100 H26 aluminum alloy is approximately between 120-170 MPa. It has lower strength than the annealed state (O) and the full-hard state (H28), positioned between the two.
Yield Strength: Due to partial annealing, the yield strength of 1100 H26 lies between the O and H28 states, exhibiting a moderate increase in strength.

1100 H26 Aluminum Heat Treatment and Work Hardening

Partial Annealing: 1100 H26 aluminum alloy undergoes strain hardening followed by partial annealing, which enhances its strength while maintaining some formability. This treatment makes it neither too hard (like the H28 state) nor too soft (like the O state).
Hardness Increase in H26 State: Due to strain hardening, the hardness of the aluminum alloy in the H26 state is higher but not at the maximum hardness, making it suitable for applications that require a balance of strength and formability.

1100 H26 Aluminum Applications

Storage Tanks and Containers: 1100 H26 aluminum is commonly used in manufacturing storage tanks, containers, and other applications requiring corrosion resistance and moderate strength, especially in chemical storage and liquid containers.
Aerospace Components: In the aerospace field, 1100 H26 aluminum is applied to non-load-bearing structural components, external devices, interiors, and other parts requiring excellent corrosion resistance and good machinability. Its strength makes it suitable for low-load components.
Construction Applications: In the construction industry, 1100 H26 aluminum is used for structural components requiring high formability, especially in external decorations, roofing materials, and curtain wall systems. Its good corrosion resistance and moderate strength are ideal for these applications.
Other Industrial Applications: Due to its excellent machinability and high corrosion resistance, 1100 H26 aluminum is widely used in other industrial fields, such as electronic device casings, condensers, conductive parts, etc.
