Ultra wide aluminum coils reach a width of 2650mm, far exceeding the typical width of standard aluminum coils (typically between 1000mm and 1500mm). This extra wide specification meets the needs of specialized applications for large-area sheets, reduces splicing, and improves production efficiency and product quality. Ultra wide aluminum coils up to 2650mm are typically used in specific industrial applications such as construction, aviation, and automotive.
The SMS 2800mm six-high cold rolling mill produces ultra wide aluminum coil as thin as 0.2mm in widths up to 2650mm. It can produce a full range of aluminum alloys from Series 1000 to 8000, offering excellent sheet shape, smooth and fine surface finishes, tight thickness tolerances, and enhanced deep drawing and oxidation performance. These ultra wide aluminum coil products are suitable for a variety of applications, including wide curtain wall panels, automotive, and marine applications.
The 2850mm wide coating line provides ultra wide color coated aluminum coils for carriages. The aluminum sheets range in thickness from 0.8mm to 2.0mm and are up to 2650mm wide, providing material for various composite panels and vehicle manufacturing industries.
Alloy Series and Properties of Ultra Wide Aluminum Coil:
1000 Series Aluminum Alloys:
These alloys, such as 1050 and 1060, belong to the pure aluminum series and offer excellent electrical and thermal conductivity and corrosion resistance. They have relatively low strength and are easily processed and molded, making them commonly used in electrical and electronic applications where strength requirements are low.
3000 Series Aluminum Alloys:
These alloys, represented by 3003, are aluminum-manganese alloys with excellent corrosion resistance, weldability, and processability. They also offer moderate strength and are used in building curtain walls and automotive manufacturing.
5000 Series Aluminum Alloys:
These alloys, such as 5052 and 5083, are aluminum-magnesium alloys with high strength, good corrosion resistance, and weldability. 5052 is commonly used in the manufacture of fuel tanks and silos, while 5083 is widely used in the manufacture of ships and naval vessels.
6000 Series Aluminum Alloys:
These alloys, such as 6061 and 6063, are aluminum-magnesium-silicon alloys with moderate strength, good corrosion resistance, and heat-treatable properties. They are widely used in building doors and windows, automotive parts, and other applications.
BCM offer ultra wide aluminum coil with high product quality:
- Excellent Plate Shape:
Advanced rolling technology and equipment are used to effectively control the plate shape, achieving high levels of flatness and convexity in the aluminum coil, meeting various processing and application requirements.
- Excellent Surface Quality:
The cold rolling process effectively prevents the effects of high temperatures on the aluminum coil surface, resulting in a smooth and fine surface free of defects such as roughness, pitting, and indented scale. Strict quality control is implemented throughout the production process to ensure consistent surface quality.
- Small Thickness Tolerance:
High production precision enables precise control of the aluminum coil thickness, resulting in tight thickness tolerances and consistent product quality, facilitating subsequent processing and use.
- Excellent Deep Drawing and Oxidation:
Specialized processing ensures excellent deep drawing performance for complex parts. The oxidation effect is also excellent, resulting in a uniform and dense oxide film with excellent wear resistance, corrosion resistance, and decorative properties.
