1100 H18 aluminum refers to 1100 aluminum alloy that has been processed to the H18 temper. 1100 H18 aluminum alloy is suitable for applications requiring high strength, but its lower ductility needs to be considered during use and processing.
The H18 temper is a hardness state of aluminum alloy obtained after severe cold working (strain hardening). This processing method increases the strength and hardness of the aluminum during plastic deformation, thereby enhancing its mechanical properties. Compared to other tempers, H18 aluminum alloy has higher strength, but its ductility and workability are relatively lower.

1100 H18 aluminum sheet is suitable for applications that require high strength, such as manufacturing components with high strength requirements.
The 1100-H18 aluminum sheet is primarily used as a substrate for PCBs (printed circuit boards) in the electronics industry. Its high strength and good thermal conductivity make it an ideal choice for heat dissipation management. The hardness and strength of the aluminum sheet help provide stable support and protection while enhancing the heat dissipation of electronic components.
Example Applications: Used in the manufacture of high-performance LED lighting, heat sinks, and other electronic device substrates.
The 1100 H18 aluminum sheet, with its high strength and rigidity, is highly suitable for making ceiling fan blades. The strength of the aluminum sheet ensures stability and durability of the fan blades during operation, while its lightweight properties help improve the efficiency and performance of the fan.
Example Applications: Used in the production of ceiling fan blades, ensuring smooth operation and long-term use of the fan.
Note: 1100 H18 aluminum sheet is not suitable for applications that require high ductility and complex processing.
The main differences between 1100 H14 and 1100-H18 aluminum grades lie in their mechanical properties, processing methods, and resulting performance.
| Feature | 1100-H14 Aluminum | 1100-H18 Aluminum |
| Temper | Strain-hardened temper. Partially hardened through cold working but not fully hardened. | Fully hardened temper. Subjected to a higher level of strain hardening. |
| Hardness | Medium hardness, between fully annealed (O temper) and fully hardened (H18). | Higher hardness, stronger strength, but reduced formability. |
| Strength | Moderate tensile strength, suitable for applications requiring good formability and moderate strength. | High tensile strength, more suitable for applications requiring higher strength. |
| Ductility | Good ductility, easy to form and process. | Lower ductility, increased hardness reduces flexibility, more prone to cracking. |
| Formability | Excellent formability, suitable for bending, stamping, and deep drawing processes. | Reduced formability, more challenging to process. |
| Common Uses | Automotive interiors, building panels, kitchenware, and consumer products requiring a balance of strength and ease of processing. | Structural components, heavy-duty applications, and other situations requiring higher strength. |
