Aluminum coils are integral to many industries, particularly when specific mechanical properties and resilience are required without compromising material weight. Among the various aluminum alloys, Aluminum Coil 1mm Thick 5052 in H34 and H32 tempers stands out as a highly versatile and functional product known for its excellent durability and wide application range.
Aluminum 5052 alloy is primarily composed of magnesium (Mg), which enhances its corrosion resistance, formability, and strength compared to pure aluminum. The 1mm thickness is a popular dimension offering flexibility for forming and structural use, while ensuring enough rigidity and surface integrity.
The tempers H34 and H32 refer to different hardening processes that balance strength and ductility for distinct needs:
- H34 temper: Strain-hardened and partially annealed for medium hardness
- H32 temper: Strain-hardened and stabilized with less hardening than H34 (half hard)
These tempers influence fatigue strength, bending capabilities, and wear resistance.

Working with 5052 H34 and H32 aluminum coil at 1mm thickness presents a unique set of challenges and advantages. The 5052 alloy itself is prized for its excellent corrosion resistance, making it ideal for applications demanding longevity outdoors or in harsh environments. However, at 1mm, the material is relatively thin and requires careful handling during processing to avoid scratching, denting, or even tearing. We frequently see issues with edge burring during slitting, necessitating extra attention to our machinery's maintenance and the use of specialized tooling. The H34 temper, being slightly softer than the H32, allows for easier forming but requires more consideration during storage to prevent warping or bowing. We've found that optimal stacking and palletizing are crucial to maintain flatness.
The difference between H34 and H32 tempers is subtle yet impactful. While both are suitable for a wide range of applications, the slightly harder H32 offers better dimensional stability, especially important in situations where precise tolerances are critical, like automotive parts or certain types of construction materials. We see a higher demand for the H32 due to this enhanced stability, but the H34's malleability keeps it consistently popular for applications involving more complex forming processes. these nuances, along with the inherent challenges of working with thin gauge aluminum, has been to our team's success in consistently delivering high

Alloy Tempering and Mechanical Behavior
H34 Temper: Produced by strain hardening from the H18 condition, followed by partial annealing to relieve stresses while preserving significant hardness and strength. This makes 5052 H34 coils suitable for parts requiring rigidity combined with modest forming ability, such as marine vessels, fuel tanks, and automotive panels.
H32 Temper: Achieved through strain hardening stabilized at intermediate levels to maintain good ductility alongside moderate hardness. H32 5052 aluminum coils are ideal for curved automotive body parts, architectural panels, and other shapes where medium formability is necessary while maintaining resistance to deformation.
