3000 Series Mill Finish Aluminum Coil
The 3000 Series Mill Finish Aluminum Coil belongs to the Al-Mn alloy, which is well known for its excellent corrosion resistance, stable mechanical properties, and outstanding formability. With manganese content between 1.0% and 1.5%, this alloy delivers a good balance of strength and ductility, making it a trusted choice across industries such as construction, transportation, packaging, and HVAC manufacturing.
Unlike pure aluminum (1000 series), the addition of manganese significantly improves strength without sacrificing corrosion resistance. As a result, 3000 series coils are widely used in roofing, siding, cladding, beverage packaging, and appliance manufacturing where durability and long service life are essential.
Excellent resistance to corrosion in humid, salty, or industrial environments
Stable mechanical strength with long-term reliability
Good weldability and formability for complex processing
Smooth and uniform surface suitable for coating, painting, or anodizing
Cost-effective material with a long service life and low maintenance

FAQ
Q: What makes 3000 series different from 1000 series aluminum coil?
A: The 3000 series contains manganese, which increases strength while maintaining corrosion resistance. It performs better in roofing, siding, and packaging applications where both durability and mechanical reliability are important.
Q: Is this material suitable for coastal or humid environments?
A: Yes, the alloy's strong corrosion resistance makes it highly suitable for marine and coastal applications.
Q: Can you supply coils in customized dimensions?
A: Absolutely. We offer precision slitting, custom width, and cutting-to-length services to match project requirements.
Q: What surface finishes are available besides mill finish?
A: We provide options including color-coated, anodized, and embossed finishes.
Q: What is the minimum order quantity?
A: The MOQ depends on thickness and alloy grade. Please contact us for specific details.
