Cold rolled aluminum strip is an aluminum alloy material processed by cold rolling. Cold rolled aluminum strip usually has good surface quality, high strength, excellent plasticity and good formability. It is widely used in construction, packaging, electronics, transportation and other fields.

When producing cold rolled aluminum strip, it usually goes through a series of process steps, including smelting, casting, hot rolling, cold rolling and annealing, to achieve the required thickness and performance requirements. The thickness of cold-rolled aluminum strip is usually thin, and the common thickness range is between 0.1mm and 5mm.

The biggest difference between cold rolled aluminum strip and hot rolled aluminum strip lies in its unique "cold processing" process. After multiple cold rolling processes, the thickness accuracy of the aluminum strip can be controlled within ±0.01 mm, which is equivalent to 1/5 of the diameter of a hair. This extreme precision allows it to meet the stringent requirements of electronic components - for example, the battery shell of a mobile phone must be both light and portable, and have sufficient structural strength. The cold rolled aluminum strip increases the tensile strength by more than 30% through the cold rolling hardening effect, perfectly balancing weight and performance.​

In the field of automobile manufacturing, cold rolled aluminum strips shine even more. The 5000 series aluminum alloy strips we export to Europe are used in the battery pack shells of new energy vehicles. Its surface roughness can be controlled below Ra0.8, which can directly meet the requirements of electrophoretic coating, eliminating the secondary grinding process and reducing the processing cost for car companies by 15%. Japanese customers are particularly fond of our 3000 series aluminum strips. Due to its good stamping performance, it has become an ideal material for automobile heat sinks and can maintain stable thermal conductivity under the high temperature environment of the engine compartment. ​

Customers in the electronics industry have almost stringent requirements for the flatness of cold rolled aluminum strips. The 1060 pure aluminum strips we customized for Korean electronics manufacturers have a wave degree of no more than 2 mm per meter to ensure that no wrinkles will be generated during high-speed stamping. This precision comes from the twenty-roll rolling mill imported from Germany that we introduced, which can "iron" every tiny defect of the aluminum strip like a precision instrument. ​

The packaging field has witnessed another charm of cold rolled aluminum strips. The production of pharmaceutical aluminum foil requires extremely high purity of aluminum strips. The 8011 aluminum strips we export undergo six degreasing and cleaning steps, and the surface oil residue is less than 5mg/m², which fully complies with EU pharmaceutical packaging standards. The aluminum strips for food packaging exported to Australia last year, with a uniform thickness of 0.03 mm, not only ensure good sealing, but also achieve lightweight packaging. The weight of a single roll is 20% lighter than traditional materials.

As an exporter, we know that every roll of aluminum strip carries the trust of our customers. From raw material screening to finished product testing, we adhere to 18 quality control processes to ensure that every batch of products delivered can bloom on production lines around the world. This is the power of cold rolled aluminum strips - empowering thousands of industries with precision manufacturing.
