Chalco Aluminum Coil Processing Capabilities
Chalco possesses first-class aluminum coil deep processing production lines, capable of precisely processing high-quality aluminum coils into various aluminum sheets and aluminum strips through advanced leveling and cutting equipment. The cut-to-length process combines multi-roll tension leveling and CNC shearing to ensure excellent flatness and controllable thickness tolerance of the finished sheets. The slitting process utilizes high-precision slitting machines and online edge trimming systems to achieve an aluminum strip width tolerance of ±0.1 mm and burr-free edges, fully meeting the requirements for subsequent processing such as stamping, bending, and welding.
Aluminum Coil Cross Cutting – 3003 Aluminum Sheet
3003 aluminum coils are unwound on decoilers, leveled by multi-roll combinations to eliminate internal stress and waviness, and then precisely cut to the customer's specified length (100 mm–6000 mm) by a PLC-controlled shearing mechanism. Protective film can be applied to the surface of the finished sheets to ensure no scratches or creases.
Standard Sizes
| Dimensions (mm) | Typical Uses |
| 1000×2000 | Curtain wall panels, decorative panels |
| 1220×2440 (4′×8′) | Architectural decoration, furniture panels |
| 1250×2500 | Machinery shells, large equipment guard plates |
| 1500×3000 | Ship skins, rail transit interiors |
*Chalco can customize ultra-wide aluminum coil (≤ 2650 mm) or ultra-long (≤ 6000 mm) sheets.
Applications
3003 aluminum sheets are widely used in building curtain walls, mechanical equipment panels, and furniture decoration. Their high flatness and straightness meet the requirements for spraying, bending, and assembly. Their weather resistance and aesthetics also make them an ideal substrate for advertising signs and interior partitions.
Aluminum Coil Slitting – 3003 Aluminum Strip
3003 aluminum coils are pulled by high-precision slitting machines with automatic tension control into the slitting unit. The slitting width is flexibly adjustable (10–500 mm), and the thickness range is 0.2–3.0 mm. After slitting, online edge trimming and tension leveling are performed, and the aluminum strips are output in tightly wound coils, ensuring clean edges and stable dimensions.

If your priority is excellent formability, superior corrosion resistance, and good electrical and thermal conductivity, with lower strength requirements, then 1100 aluminum coil is your ideal choice.
If you need a good balance between strength, corrosion resistance, and formability, and are looking for a versatile and widely applicable material, then 3003 aluminum coil is a solid choice.
If your application environment is harsh (e.g., marine or industrial) and you have high demands for material strength and corrosion resistance, while also considering fatigue strength, then 5052 aluminum coil is a more suitable option.
We hope the above comparative analysis of 1100, 3003, and 5052 aluminum coils can help you make a better choice. If you have any other questions or need a more in-depth discussion, please feel free to contact us at any time!Contact us

Frequently Asked Questions
Is there a high risk of cracking when 3003 aluminum coil is subjected to complex bending? How can it be avoided?
3003 has good formability, but excessive bending still carries a risk of cracking. Choose a soft temper (O) or a suitable semi-hard temper (H12/H14), and pay attention to the bending radius, die design, and processing speed.
Will a humid environment corrode 3003 aluminum coil? Is extra protection needed?
3003 has better corrosion resistance than pure aluminum and can handle general humid environments. For long-term exposure to high humidity or corrosive media, surface treatments such as anodizing are recommended.
When welding 3003 aluminum coil, how can strength be guaranteed and cracking avoided?
Select a matching welding wire (such as ER4043/ER5356), precisely control welding parameters, thoroughly clean the weld, and avoid rapid cooling to prevent stress.
Can 3003 aluminum coil be directly painted or anodized? What is the effect?
Yes. Paint adhesion is good, and anodizing can improve wear resistance, but the color of the oxide film may not be as vibrant as that of other alloys.
How much more expensive is 3003 aluminum coil than 1100? How much cheaper is it than 5052? How can I find the most cost-effective option?
The price is between 1100 and 5052. Choose the appropriate temper based on strength and corrosion resistance requirements, optimize material usage, and partner with reliable suppliers.
