1100 3003 3004 Alloy Color Coated Aluminum Coil
Color coated aluminum coil has emerged as a highly versatile product used in various applications, notably in construction and manufacturing. This comprehensive guide specifically focuses on the 1100, 3003, and 3004 alloys, commonly used in conjunction with color coating processes to enhance durability, aesthetics, and functionality.
1100 Alloy
The 1100 alloy is commercially pure aluminum and comprises a minimum of 99.0% aluminum content. Its excellent corrosion resistance and formability make it suitable for various industrial applications.
3003 Alloy
The 3003 alloy is part of the 3000 series and comprises around 20% more strength than 1100 alloy fat due to the addition of manganese. It is highly malleable and offers good workability under various temperatures.
3004 Alloy
The 3004 alloy includes manganese and magnesium, which enhances paint adhesion and improves strength for high-stress applications. It is engineered for superior formability and moderate corrosion resistance.
