Different levels of hardness and strength can be achieved through various heat treatments for aluminum coils, resulting in different tempers. These tempers alter the physical and mechanical properties of the coils to suit specific applications.
Aluminum coils can undergo different tempering processes to modify their properties. The most common tempers for aluminum coils are as follows:
1. O Temper (Soft): This represents the annealed state of aluminum, where the metal is fully soft and easily moldable. It has low strength but excellent ductility, making it suitable for applications that require extensive shaping or bending.
2. H14 Temper (Half Hard): This offers moderate strength and hardness, while still maintaining some formability. It is used in applications that require a balance between strength and flexibility, such as roofing or cladding.
3. H18 Temper (Hard): This provides high strength and hardness, with reduced formability. It is commonly used in applications that demand structural integrity and resistance to deformation, such as automotive parts or industrial equipment.
4. H22, H24, H26 Temper (Extra Hard): These tempers are achieved through additional cold working or strain hardening processes. They offer even higher strength and hardness but sacrifice some ductility. They are often used in applications that require enhanced mechanical properties, such as aerospace components or high-stress structural parts.
5. T Temper (Tension Leveled): This involves stretching the aluminum coil beyond its elastic limit and then stabilizing it. It helps eliminate internal stresses and improve flatness, making it suitable for applications that demand precise dimensional stability, such as electronic devices or architectural panels.
It's important to note that there are many other tempers available for aluminum coils, each designed to meet specific requirements. The choice of temper depends on factors such as the intended application, desired mechanical properties, and processing capabilities.
The different tempers of aluminum coils refer to the varying levels of hardness and strength that can be achieved through different heat treatments. Aluminum coils can be subjected to various tempering processes to alter their physical and mechanical properties for specific applications.
The most common tempers for aluminum coils include:
1. Soft (O Temper): This temper represents the annealed state of aluminum, where the metal is fully soft and easily formable. It has low strength but excellent ductility, making it suitable for applications that require extensive shaping or bending.
2. Half Hard (H14 Temper): This temper offers moderate strength and hardness, while still retaining some formability. It is used in applications where a balance between strength and flexibility is necessary, such as roofing or cladding.
3. Hard (H18 Temper): This temper provides high strength and hardness, with reduced formability. It is commonly used in applications that demand structural integrity and resistance to deformation, such as automotive parts or industrial equipment.
4. Extra Hard (H22, H24, H26 Temper): These tempers are achieved through additional cold working or strain hardening processes. They offer even higher strength and hardness but sacrifice some ductility. They are often utilized in applications that require enhanced mechanical properties, such as aerospace components or high-stress structural parts.

The different tempers of aluminum coils refer to the various stages of heat treatment and mechanical processing that aluminum undergoes to achieve desired properties. These tempers include annealed, H12, H14, H16, H18, H22, H24, H26, H32, H34, H36, H38, T4, T6, and T651. Each temper offers specific characteristics in terms of hardness, strength, formability, and corrosion resistance, making them suitable for different applications.
