The alloy selection of patterned aluminum plate needs to comprehensively consider strength, corrosion resistance, processability and surface treatment requirements. According to the differences in application scenarios, the following aluminum alloy series are mainly used:
1. Mainstream alloy types and typical grades
| Alloy Series | Common Grades | Core Characteristics | Typical Application Scenarios |
|---|---|---|---|
| 1xxx series (Pure Al) | 1050/O, 1060/O, 1100/O | High ductility (≥25%), excellent electrical/thermal conductivity | Decorative non-slip pedals (stairs/indoors) |
| 3xxx series (Al-Mn) | 3003/H14, 3004/H34 | Medium strength, excellent corrosion resistance, easy welding | Building roof/curtain wall substrate |
| 5xxx series (Al-Mg) | 5052/H32, 5083/H111, 5086 | High strength (tensile strength ≥260 MPa), resistance to salt spray corrosion | Industrial equipment walkway, ship deck, vehicle bottom plate |
2.Alloy performance and scene adaptability
1xxx series Checker Plate (purity ≥99%)
Advantages: Excellent ductility, suitable for complex stamping (such as deep-drawn cans), low cost
Limitations: Low strength (tensile strength of about 85-110MPa), not suitable for heavy-loaded structures
5xxx series Checker Plate (containing 2-5% magnesium)
Strengthening mechanism: solid solution strengthening + cold work hardening (H32/H34 state)
Performance highlights:
5052 Checker Plate: Balanced strength and formability (tensile strength 210-260MPa)
5083 Checker Plate: Strong impact resistance, suitable for extreme environments (such as ships/polar vehicles)
Special needs selection
Wear resistance: Select 2xxx series Checker Plate (such as AlCuMg) for aging treatment, hardness up to 150 HB
Surface decoration: Anodizing or spraying process is suitable for 1xxx/3xxx series (such as imitation wood grain curtain wall panels)
3.Surface treatment process matching
| Process Type | Applicable Alloy Series | Effect |
|---|---|---|
| Anodizing | 1xxx / 5xxx / 6xxx series | Improves wear resistance, allows customized colors (e.g., champagne gold, black) |
| Fluorocarbon Spraying | 3xxx / 5xxx series | Enhances outdoor weather resistance (UV protection, acid rain resistance) |
| Embossed / Punched | 1xxx / 3xxx series |
Improves anti-slip performance and breathability (e.g., industrial platforms) |
4.Industry application recommendation table
Industry Recommended alloy Key parameter requirements
Architectural decoration 3003-H14, 5052-H32 Thickness 1.5-3mm, corrosion resistance ≥10 years
Heavy transportation 5083-H111, AlCuMg-T6 Tensile strength ≥400MPa, salt spray resistance test passed
Electronic heat dissipation 1050-O, 1100-O Thermal conductivity ≥ 200 W/(m·K), surface flatness ≤ 0.1mm
Conclusion: The mainstream materials of patterned aluminum plates are 1xxx, 3xxx and 5xxx series aluminum alloys, among which 5052 and 5083 are the first choice in the industrial field due to their high strength and corrosion resistance, while 1xxx series pure aluminum dominates the decoration and lightweight scenes. When selecting, it is necessary to prioritize the matching of load strength, environmental weather resistance and processing technology requirements.
