| Manganese (Mn) | ≤ 0.10 |
| Iron (Fe) | ≤ 0.40 |
| Copper (Cu) | ≤ 0.10 |
| Silicon (Si) | ≤ 0.25 |
| Zinc (Zn) | ≤ 0.10 |
| Titanium (Ti) | ≤ 0.03 |
| Others | ≤ 0.05 each, total ≤ 0.15 |
Mechanical Properties
The mechanical properties of aluminum 5052 alloy show remarkable strength combined with good ductility and formability. Typical typical mechanical values for different tempers are as follows:
| Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (Brinell) |
|---|---|---|---|---|
| H32 | 228 – 265 | 193 – 214 | 8 – 15 | 75 – 85 |
| H34 | 270 – 300 | 230 – 250 | 10 – 12 | 85 – 95 |
| H38 | 290 – 320 | 260 – 280 | 7 – 9 | 95 – 105 |
| O (annealed) | 145 – 190 | 90 – 120 | 15 – 22 | 40 – 50 |
Note: Actual properties may vary slightly based on processing and supplier.
Features and Benefits
1. Excellent Corrosion Resistance
The magnesium content significantly improves corrosion resistance especially to seawater and marine atmosphere corrosion. This makes 5052 plates ideal for shipbuilding, offshore structures, and chemical plants.
2. High Strength
With its higher strength than pure aluminum and some other alloys, 5052 is commonly used in pressure vessels and lightweight components without compromise on durability.
3. Superior Weldability and Formability
This alloy type can be easily welded by MIG, TIG, and resistance methods without excessive loss in strength or corrosion resistance. Also, it exhibits excellent cold formability, allowing bending, stamping, and rolling operations.
4. Good Fatigue Resistance
5052 aluminum alloy tends to have robust fatigue strength which is useful in automotive, aerospace, and structural components subjected to dynamic stresses.
5. Non-Heat Treatable
As a non-heat treatable alloy, it relies on work hardening to reach desired mechanical properties, thus manufacturing processes involve mostly cold working for strengthening.
Typical Applications
Due to its combination of mechanical performance and corrosion resistance, aluminum alloy 5052 plates serve multiple industries:
| Application Sector | Specific Uses |
|---|---|
| Marine | Boat hulls, decks, bulkheads, fuel tanks, yacht panels |
| Transportation | Truck tanker bodies, trailers, fuel tankers, bus bodies |
| Construction | Roofing sheets, wall panels, siding, soffits |
| Electrical | Components for electrical enclosures and bus bars |
| Aerospace | Fuselage panels, structural racks, avionics housing |
| General Manufacturing | Pressure vessels, storage tanks, kitchen utensils, packaging |
