Detailed Product Description

Gengfei Steel supplies premium 3003 aluminum coils, a versatile and widely used non-heat-treatable alloy. With the addition of manganese (~1.2%), 3003 offers higher strength than 1xxx series aluminum while retaining superb workability and corrosion resistance.

This alloy performs well in both indoor and outdoor environments, especially where moisture and mild chemicals are present. Gengfei provides 3003 coils in various tempers (O, H14, H16, H18, H24, etc.), thicknesses, and surface treatments such as mill finish, color coating, and stucco embossing.

Whether you’re manufacturing kitchenware, cladding commercial buildings, or insulating ductwork, 3003 aluminum coil provides a cost-effective and high-performance solution.

FAQ – 3003 Aluminum Coil

Q1: What is the difference between 3003 and 1100 aluminum coil?
3003 has higher strength and better corrosion resistance due to the addition of manganese. It’s more suitable for roofing and cookware.

Q2: Is 3003 aluminum coil good for welding?
Yes, 3003 is highly weldable using conventional methods like TIG and gas welding.

Q3: Can 3003 aluminum be anodized or color coated?
Yes, we offer 3003 coils in anodized and color-coated finishes (PE/PVDF).

Q4: Is 3003 suitable for outdoor use?
Yes, 3003 performs well in humid and moderately corrosive environments.

Q5: What’s the lead time for orders?
Typically 15–30 working days depending on quantity and finish requirements.
