Common Alloys for 4mm Aluminium Checker Plate
For 4mm aluminium checker plate, the most commonly used alloys are 3003, 5052, and 6061, each tailored to specific performance requirements.
Alloy 3003
- Composition: Al-Mn alloy (manganese content 1–1.5%), with excellent corrosion resistance and formability.
- Temper: Typically H22 (strain-hardened and partially annealed) to balance strength and workability.
Key Features:
- Decorative: Known for its bright surface, often used in architectural decoration, signage, and decorative flooring.
- Corrosion Resistance: Suitable for indoor or mild outdoor environments, such as truck toolboxes and cargo vehicles.
- Formability: Easy to bend or weld, making it ideal for custom fabrication projects.
- Limitation: Lower strength compared to 5052 or 6061, making it less suitable for heavy-duty structural applications.
Alloy 5052
- Composition: Al-Mg alloy (Mg content 2.2–2.8%), with high corrosion resistance and medium strength.
- Temper: Commonly H32 (strain-hardened and stabilized) to enhance durability.
Key Features:
- Marine Grade: Resistant to seawater and humid environments, widely used in ship decks, offshore platforms, and refrigerated trucks.
- Strength: Tensile strength (230–280 MPa) is higher than 3003, suitable for medium-load applications such as loading ramps and trench covers.
- Workability: Retains good formability even after heat treatment, allowing complex shapes for specialized designs.
- Applications: Refrigerated flooring, marine hardware, and industrial flooring where anti-slip and corrosion resistance are critical.
Alloy 6061
- Composition: Al-Mg-Si alloy (0.8–1.2% Mg, 0.4–0.8% Si), offering high strength and weldability.
- Temper: T6 (solution heat-treated and artificially aged) is the standard condition for maximum strength.
Key Features:
- Structural Performance: Highest strength among the three alloys, suitable for load-bearing applications such as truck beds, machinery platforms, and aircraft components.
- Machinability: Easy to machine and weld, ideal for custom projects.
- Corrosion Resistance: Moderate corrosion resistance, suitable for general industrial use, but less ideal for marine environments without additional coating.
- Applications: Structural frameworks, automotive parts, and heavy-duty flooring requiring high rigidity.
Other Considerations
- Thickness-Specific Requirements: For 4mm plates, 6061-T6 is generally more suitable for structural integrity, while 5052-H32 performs better in corrosive environments. 3003-H22 is an economical choice for decorative or low-stress applications.
- Surface Finish: Anodizing or powder coating can enhance corrosion resistance and aesthetics, especially for 3003 and 5052.
- Standards: These alloys comply with international specifications such as ASTM B209 and GB/T 3618-2006, ensuring consistency in quality and performance.
Summary of Alloy Selection
| Alloy | Key Advantages | Ideal Applications |
| 3003 | Corrosion resistance, decorative finish | Truck toolboxes, architectural trim, signage |
| 5052 | Marine-grade corrosion resistance | Ship decks, refrigerated trucks, cold storage |
| 6061 | High strength, weldability | Truck beds, machinery platforms, structural framing |
By matching the alloy to the specific environment and load requirements, 4mm aluminium checker plates can deliver optimal performance in anti-slip flooring, transportation, and industrial settings.
