5052 1mm 2mm Thin Aluminium Sheet
Aluminum sheets, especially those manufactured from the 5052 alloy series, have become indispensable in modern industry. Among the variety of options, the 5052 aluminum sheet with thin gauges such as 1mm and 2mm thicknesses presents a specialized solution renowned for combining strength, excellent corrosion resistance, and remarkable workability.
What Is 5052 Aluminum Sheet?
The 5052 aluminum sheet is an alloy primarily made from aluminum and magnesium (Mg), with aluminum as the major constituent (approx. 97.25% or greater), alongside trace elements such as chromium for increased strength and corrosion resistance. This non-heat-treatable alloy belongs to the 5xxx series and is widely favored for superior performance in marine, automotive, and chemical environments. The designation “5052” identifies the chemical composition within the Al-Mg system consistent with established standards such as ASTM B209.
The typical thicknesses of 1mm and 2mm qualify as thin sheets, providing lightweight yet tough materials optimal for diverse manufacturing tasks.
Functional Characteristics
Superior Corrosion Resistance:Thanks to the added magnesium (typically around 2.5%), and minor amounts of chromium (~0.15-0.35%), 5052 sheets notably resist seawater and marine atmospheres. Their ability to form an oxide-hosting protective film over surfaces sustains longevity during outdoor and automotive exposure.
Good Medium to High Strength:When compared to purer aluminum grades, 5052 offers enhanced mechanical strength. Thickness grades at 1mm and 2mm excellently maintain rigidity for precision fabrication without excessive bending or warping.
Excellent Workability & Anodizing Ability:Owing to alloy temper conditions (commonly H32, H34, and H36 tempers provide a balance of strain hardening and height), 5052 sheets offer stretch formability, ideal for bending, rolling, and deep drawing procedures.
Welding and Joining Benefits:Due to its chemical makeup, this alloy is highly compatible with methods like TIG and MIG welding, facilitating assembly of complex painel designs while retaining strength.
Alloy Temper Condition of 5052 Aluminium Sheet
Thin 5052 sheets in 1mm or 2mm thicknesses are rarely supplied in fully annealed conditions; tempering imparts well-controlled mechanical properties.
| Temper | Condition Description | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|---|
| O | Full Anneal (soft) | 165 | 83 | 18 - 22 |
| H32 | Strain-Hardened, Stabilized | 228 | 193 | 8 - 12 |
| H34 | Harder Heat Strengthened Option | 258 | 232 | 6 - 10 |
| H36 | Highest Strength Temper through Hardening | 277 | 249 | 5 - 8 |
The temper H32 is most prevalent in thin sheets since it balances ductility and strength for general forming and assembly purposes.
Detailed Chemical Composition
For adherence to ASTM B209 and EN 485 standards, the compositional range of 5052 sheets is tightly controlled:
| Element | Composition Range (%) |
|---|---|
| Aluminum (Al) | Balance (approx. 97.0 min) |
| Magnesium (Mg) | 2.2 – 2.8 |
| Chromium (Cr) | 0.15 – 0.35 |
| Iron (Fe) | ≤ 0.4 |
| Copper (Cu) | ≤ 0.1 |
| Manganese (Mn) | ≤ 0.1 |
| Silicon (Si) | ≤ 0.25 |
| Zinc (Zn) | ≤ 0.1 |
| Titanium (Ti) | ≤ 0.03 |
| Others | ≤ 0.05 |
The magnesium-magnesium relationship and trace metals are driven to precisely regulate strength and corrosion integrity.
Implementation Standards and Quality Control
5052 aluminum sheets in thin gauge meet international aluminium sheet standards such as:
- ASTM B209 – Standard Specification for Aluminum and Aluminum-Alloy Sheet and Plate
- EN 485-2 – Aluminum and Aluminum Alloys: Sheet, strip, and plate mechanical properties
- QQ-A-250/11 – Chemical and mechanical standards for 5xxx series
During manufacturing, suppliers perform rigorous inspection including dimensional and surface defect testing (roughness, flatness), tensile tests per standard protocols, and plating compatibility samples for anodization consistency.
Applications of 5052 Thin Aluminum Sheet (1mm & 2mm)
Owing to its thin profile, balanced strength, corrosion resistance, and malleability, 5052 aluminium sheets find applications in:
- Marine Equipment: Boat hulls, yacht components, and decks withstand harsh saline exposure
- Automotive Panels: Underbody panels, fuel tanks, truck rims that need rust protection, and lightweight composites
- Aircraft Interiors: Seatpanels and floor plates requiring low-density strong metals
- Chemical Storage and Tanks: Due to non-ferrous benefits and corrosive chemical compatibility
- Kitchen and Consumer Goods: Roofing sheets, refrigerator units, and siding sheets that are both durable and attractive
- Electrical Cabinet and Enclosure casings: High resistance to salts, acids ensure broad electronics housing usage
- Architectural Facades: Combining sturdiness with decorative anodized finishes
