3003 aluminum coil
3003 Aluminum Coil Description
The aluminum-manganese alloy 3003 is a member of the 3000 series (also known as the 3xxx series). Although heat treatment cannot strengthen this alloy, cold working can improve it. Similar to other aluminum-manganese alloys, 3003 aluminum coil exhibits exceptional corrosion resistance, good machinability, and moderate strength.
Although rolling and extrusion are common processing techniques for 3003 aluminum coil, casting is not an appropriate method. It is frequently utilized in applications like gutters, downspouts, roofing, and wall panels that call for good formability and weldability.
In comparison to the 1100 alloy, the popular aluminum-manganese alloy 3003 provides greater strength and improved corrosion resistance. It works well for a range of applications that call for superior formability and weldability.
The 3003 aluminum coil is made of pure aluminum with 1.0–1.5% manganese added, which greatly increases the material's strength and resistance to corrosion while preserving its lightweight properties (density of about 2.73 g/cm³).

3003 Aluminum Coil Production Process
Melting and Casting: To create a homogenous aluminum liquid that is subsequently cast into ingots, manganese and other raw materials are melted at high temperatures in proportion to the aluminum ingots.
Rolling Process: To guarantee a flat and smooth surface, rolling processes regulate the aluminum coil's thickness (0.2–10 mm) and width (600–2000 mm).
Surface Treatment: To improve appearance and functionality, high-performance coatings are applied to certain products through color coating procedures.

Our advantages
The 3003 aluminum coils are packed with several layers of protection to guarantee secure transportation and long-term storage. Our standard packaging is made to guard against mechanical damage, oxidation, moisture, and scratches.
1. Every 3003 aluminum coil is wrapped in either moisture-proof kraft paper or plastic film.
To further guard against oxidation and moisture, desiccants may be added.
2. Moderate Cushioning
To stop scratches and mechanical friction during handling, a layer of foam, cardboard, or hard kraft paper is applied.
The purpose of edge protectors is to prevent damage and preserve coil shape.
3. External Packaging
Strong steel straps hold the coil in place, and it is covered with protective film or hard paperboard.
Coils are packed in fully enclosed wooden cases or fixed on wooden pallets for export shipments, both of which adhere to international shipping regulations (fumigation treatment available).
