Aluminum coil A5052 H32 10 Mm 20mm Thickness
When it comes to aluminum coils, the A5052 alloy stands out for its remarkable blend of strength, corrosion resistance, and versatility. Particularly in sheath thicknesses of 10mm and 20mm, the A5052 H32 temper coil offers an ideal solution across multiple industrial applications.
Aluminum Coil A5052 H32: A Technical Snapshot
The A5052 is an aluminum-magnesium alloy known primarily for enhanced corrosion resistance, especially against marine and industrial environments. The “H32” designation signifies a specific temper treatment—a strain-hardened state with approximately half hard characteristics—resulting in moderate strength and exceptional formability.
Thicknesses: 10mm & 20mm
- 10mm Thickness: Strikes a balance between flexibility and bulk — optimal for forming processes where bending without cracking is necessary.
- 20mm Thickness: Offers added rigidity for structural components requiring higher stiffness and durability without compromising machinability.
This thickness flexibility allows manufacturers to optimize coil weight, durability, and mechanical response based on end-use needs.
Chemical Properties of A5052
For a nuanced of the alloy’s performance, the exact chemical composition under standard specifications is crucial. Below is the typical chemical composition for A5052 aluminum coils adhering to standards like ASTM B210 / AMS 4035.
| Element | Composition (%) |
|---|---|
| Magnesium (Mg) | 2.2 – 2.8 |
| Chromium (Cr) | 0.15 – 0.35 |
| Manganese (Mn) | ≤ 0.1 |
| Iron (Fe) | ≤ 0.4 |
| Silicon (Si) | ≤ 0.25 |
| Copper (Cu) | ≤ 0.1 |
| Zinc (Zn) | ≤ 0.1 |
| Others | ≤ 0.15 |
| Aluminum (Al) | Balance |
The elevated magnesium imparts significant corrosion resistance while maintaining excellent fatigue properties and moderate strength increases.
Temper Classification: What Does H32 Mean?
The temper label H32 is a crucial designation:
- H: Strain Hardened (cold worked but not heat treated to enhance strength)
- 3: Represents the degree of strain hardening (~50% hardness of full hard)
- 2: Corresponds to partial annealing of the H3 temper
This temper is a midpoint optimally balancing the metal’s workability (for processes like bending and forming) and its outstanding mechanical strength.
Implementation Standards:The technical fabrication and quality parameters for A5052 H32 coils generally align with:
- ASTM B209/B210: Covers aluminum and aluminum-alloy sheet and coil thickness from 0.0079" to heavier gauges, ensuring chemical composition and mechanical properties compliance.
- MIL-DTL-46027: Military specification adherence often used in defense and aerospace applications.
- EN 485: European standard governing aluminum alloy sheets and strips commonly referenced for thickness measurement and chromium/magnesium quantities.
Due to consistent performance in both corrosion resistance and mechanical integrity, the A5052 H32 coil is fully compliant within these standards for manufacturing excellence.
Typical Mechanical Parameters at 10mm & 20mm Thickness
| Parameter | 10mm Thickness | 20mm Thickness | Units |
|---|---|---|---|
| Ultimate Tensile Strength | 170 – 250 | 160 – 240 | MPa |
| Yield Strength (0.2% offset) | 110 – 190 | 105 – 180 | MPa |
| Elongation at Break | 8 – 12 | 7 – 11 | % |
| Hardness (Brinell, HB) | ~75 – 90 | ~72 – 88 | HB |
| Density | 2.68 | 2.68 | g/cm³ |
These values show robustness for demanding conditions and flexibility for intricate metal-forming.
