5454 Color Coated Aluminum Coil

The 5454 color coated aluminum coil is a high-performance decorative metal coil made from 5454 aluminum-magnesium alloy. Its surface undergoes degreasing, chemical conversion film treatment, roll coating, and baking to form a durable and vibrant color layer. This material combines the high strength, excellent corrosion resistance, and good weldability of 5454 alloy with a colorful protective coating, making it a composite material suitable for both structural and decorative applications.

As a typical medium-strength Al-Mg series alloy, 5454 aluminum contains 2.4%-3.0% magnesium with small amounts of manganese to enhance corrosion resistance and fatigue performance. Compared to 5052 alloy, 5454 offers superior high-temperature strength and better resistance to stress corrosion cracking, making it widely used in storage tanks, automotive fuel tanks, ship structures, curtain wall decorations, and transportation facilities.

After color coating, 5454 color coated aluminum coils not only have a rich and bright appearance but also resist oxidation, acid rain, UV radiation, and sea salt corrosion, making them ideal for high-end industrial and architectural applications.

Comparison with Other Alloys

• Versus 5052 Alloy: 5454 has higher tensile strength and better heat resistance, suitable for high-temperature or high-pressure environments; 5052 is lighter, better for general decorative applications.

• Versus 5754 Alloy: Similar corrosion resistance, but 5454 slightly outperforms in weldability and structural strength, better for storage tank manufacturing.

• Versus 3004 Alloy: 5454 is Al-Mg series with much higher strength and better salt spray resistance than the Al-Mn 3004 alloy.

• Versus 6061 Alloy: 6061 is stronger but less formable; 5454 is preferable for forming complex structures.

Storage and Handling

Store in a dry, ventilated, flat area, away from direct sunlight and humidity.

Avoid impact or scratches on the coil edges during handling.

Clean surface oils or debris before use to ensure proper coating adhesion.

Recommended processing at room temperature to prevent coating deformation.

FAQ

Q1: What is the difference between 5454 and 5052 color coated aluminum coils?
