Core Performance of 5754 Aluminium Chequered Plate:

1. Mechanical Performance Enhancement

- H114 Properties:

Cold work hardening achieves a hardness of HB 65-80, a tensile strength ≥190 MPa, a yield strength ≥110 MPa, and an elongation ≥12%.

- Compared to other properties:

H112 (annealed and lightly worked) has lower strength, while H24 (work hardened + partial annealing) has higher elongation, but H114 offers superior overall performance in anti-skid applications.

- Fatigue Performance:

Under alternating loads (such as vehicle vibration), aluminum chequer plate 5754 H114's fatigue life exceeds that of ordinary carbon steel, making it suitable for long-term load-bearing structures.

2. Corrosion Resistance Mechanism:

- Magnesium oxide film:

Magnesium forms a dense MgO·Al₂O₃ composite oxide film on the aluminum surface, blocking chloride ion penetration and providing seawater corrosion resistance 1.5 times that of 304 stainless steel.

- Electrochemical Protection:

In salt spray environments, 5754 aluminum chequered sheet acts as an anode, preferentially corroding, protecting connected components (such as steel brackets) and extending the life of the overall structure.

3. Quantified Anti-Slip Performance

- Friction Coefficient:

The five bar aluminum chequer plate has a dry friction coefficient of ≥0.65 and a wet friction coefficient of ≥0.45 (with a water film thickness of 1mm), significantly exceeding that of flat aluminum plates (0.3 in dry state and 0.1 in wet state).

- Drainage Design:

With a pattern spacing of 15-20mm, drainage efficiency reaches 90% at slopes ≥5%, eliminating the risk of water accumulation and slips.

4. Processing Adaptability

- Cold Formability:

Can be bent up to 90° (with an inner diameter ≥3 times the plate thickness) without cracking, making it suitable for curved decks or special-shaped structures.

- Welding Compatibility:

When welding with 5052 and 6061 aluminum alloys, the weld strength reaches over 85% of the parent material, making it suitable for the assembly of complex structures.

Application Scenarios of 5754 Aluminium Chequer Plate:

1. Shipbuilding and Marine Engineering
