Baimaoxing
Cold rolled aluminum coils (CRAC) are critical for aerospace skins and structural components. Our high-precision 2xxx and 7xxx series offer unmatched strength-to-weight ratios, ensuring fuel efficiency and structural integrity under extreme atmospheric pressure.
As the EV market expands, the demand for 5xxx and 6xxx series coils for battery enclosures and body panels has surged. Our cold-rolling process ensures the surface smoothness required for high-end paint finishes and aerodynamic optimization.
With superior conductivity, our 1xxx series aluminum coils serve as the backbone for transformer windings and heat exchangers. Cold rolling enhances the material's grain structure, providing better workability for complex stamping.
Cold rolled aluminum coil is produced by passing hot-rolled sheets through a series of rollers at room temperature. This process, unlike hot rolling, increases the material's yield strength and hardness through strain hardening. Our facility employs advanced 6-high rolling mills to achieve thickness tolerances as tight as Β±0.01mm.

Cold rolled coils are slit into fins for heat exchangers. Our hydrophilic-coated aluminum prevents water bridging, enhancing thermal efficiency.
Used for ACP (Aluminum Composite Panels) and roofing. Excellent weather resistance and formability for modern facade designs.
High-strength 5083 coils for marine shipbuilding and pressure vessels where corrosion resistance is paramount.
Hot rolling happens at high temperatures, which is better for heavy gauges but leaves a rough finish. Cold rolling happens at room temperature, providing a smoother surface, higher dimensional accuracy, and increased strength due to strain hardening.
1050 is 99.5% pure, ideal for chemical/electrical work. 3003 adds manganese for better corrosion resistance (common in cookware). 5052 adds magnesium, making it much stronger and suitable for marine environments.
For standard specifications, lead times range from 7β15 days. Custom alloys or specific surface treatments (anodizing/coating) typically take 20β30 days depending on the volume and technical requirements.
Yes, every shipment is accompanied by a Mill Test Certificate (MTC) according to EN 10204 3.1, detailing chemical composition, tensile strength, elongation, and hardness test results.
The aluminum industry is moving toward a "Circular Economy." At Baimaoxing, we are investing in low-carbon smelting processes and increasing the ratio of recycled aluminum content in our cold-rolled products. Future technical roadmaps include the development of Al-Li (Aluminum-Lithium) alloys for next-gen aerospace and enhanced Graphene-Aluminum composites for superior thermal management in 6G infrastructure.
