5754 Color Coated Aluminum Coil

The 5754 color coated aluminum coil is a decorative metal coil made from 5754 aluminum-magnesium alloy sheets. After degreasing, chemical pre-treatment, roll coating, and baking, an organic coating is formed on the surface. This material combines the lightweight, high-strength, and corrosion-resistant properties of aluminum alloy with the aesthetic appeal and weather resistance of the color coating. It is a high-end material integrating both functionality and decoration and serves as an ideal alternative to traditional steel coils and color steel sheets.

The 5754 alloy belongs to the 5xxx Al-Mg series, with magnesium content ranging from 2.6% to 3.6%. It offers medium strength, excellent fatigue resistance, and outstanding seawater corrosion resistance. After color coating, it not only improves decorative appearance but also significantly enhances surface oxidation, acid/alkali resistance, and UV resistance.

In applications such as architectural facades, ship hulls, automobile bodies, rail transport, storage tanks, and appliance panels, 5754 exhibits higher strength than 5052, making it particularly suitable for floors and curtain wall applications.

Advantages of 5754 Color Coated Aluminum Coil

1. Exceptional Corrosion Resistance: Excellent resistance to salt spray, seawater, and humid environments. Superior to 3xxx series alloys; ideal for coastal, marine, and heavy industrial areas.

2. Medium to High Strength: Higher strength than 3003 or 3105 color coated aluminum; good fatigue resistance ensures component stability and longevity.

3. Excellent Formability: Good cold workability and deep drawing performance; suitable for complex shaping, bending, and stamping.

4. Outstanding Weldability: Typical weldable alloy; welded joints maintain high strength, critical for shipbuilding and automotive applications.

5. Long-lasting Decorative Appearance: High-quality color coating provides rich colors and gloss; tightly bonded to the base material, preventing peeling and fading.

6. Environmentally Friendly & Recyclable: Free of heavy metals and VOCs; complies with RoHS and REACH standards; 100% recyclable.

Applications of 5754 Color Coated Aluminum Coil

• Construction: Exterior wall curtain systems, roof tiles, ceiling panels, aluminum honeycomb panels, roller shutter doors; used in airports, exhibition centers, metro stations, and commercial complexes.

• Transportation: Ship hulls, yacht decks, vehicle interior/exterior panels, RV exteriors, refrigerated truck bodies; vibration and fatigue resistant, lightweight, reduces energy consumption.

• Home Appliances & Industrial Equipment: Refrigerator side panels, washing machine housings, air conditioner decorative panels, machine enclosures; industrial equipment covers, elevator panels, reflector plates for lighting.

• Packaging & Storage Tanks: Food packaging, beverage cans, liquid storage tanks, chemical containers; acid/alkali resistant, ensures content safety.

Comparison with Other Alloys

• Versus 3xxx Series: Higher magnesium content provides superior salt spray and seawater corrosion resistance; ideal for ship hulls, coastal buildings, and transport equipment.

• Versus 3105 Alloy: Higher yield and tensile strength; suitable for structural applications while maintaining excellent formability and weldability.

• Versus 5052 Alloy: Similar strength with better surface smoothness and coating adhesion; widely used in curtain wall decoration and appliance panels.

Overall: 5754 color coated aluminum coil balances strength, corrosion resistance, and formability, positioning it as a medium-high strength alloy ideal for demanding decorative and structural applications.
