Product Category
Color coated aluminum coil is a high-quality, pre-painted aluminum product that is produced through a continuous coating process. This process involves applying one or more layers of organic paint to aluminum coils, which are then baked and cured to form a durable, colorful, and protective coating. This type of aluminum coil is widely used in various industries due to its aesthetic appeal, lightweight, and excellent corrosion resistance.
Types of Aluminum Material
Aluminum coils come in several grades, each with unique characteristics that make them suitable for different applications:
1. Pure Aluminum (AA1100):
- Characteristics: Soft, excellent corrosion resistance, high thermal and electrical conductivity.
- Applications: Used in applications where good workability is required, such as chemical and food processing industries, and architectural applications.
2. Aluminum-Manganese Alloy (AA3003):
- Characteristics: Good corrosion resistance, moderate strength, excellent workability.
- Applications: Used in cooking utensils, heat exchangers, and chemical equipment.
3. Aluminum-Manganese-Magnesium Alloy (AA3004):
- Characteristics: Higher strength than AA3003, good formability, and corrosion resistance.
- Applications: Commonly used in the manufacturing of beverage cans, building products, and storage tanks.
4. Aluminum-Magnesium-Silicon Alloy (AA3105):
- Characteristics: Good corrosion resistance, formability, and weldability.
- Applications: Used in residential siding, mobile homes, and rain-carrying goods.
5. Aluminum-Magnesium Alloy (AA5052):
- Characteristics: Excellent corrosion resistance, high fatigue strength, good weldability.
- Applications: Used in marine environments, fuel tanks, and pressure vessels.
6. Aluminum-Zinc Alloy (AA6061):
