Aluminum veneers can be manufactured by hot rolling or cold rolling. The specific process to be selected depends on the use environment and requirements.
The surface of hot-rolled aluminum veneers is relatively rough, but it has good plasticity and toughness, and is suitable for occasions that require bending and stamping. The hot rolling process uses the good plasticity of metal at high temperatures, with a large processing rate, high productivity and high yield rate. 12
Cold rolling usually refers to the rolling process of metal below the recrystallization temperature, which produces work hardening, increases the strength and deformation resistance of aluminum veneer metal, and is accompanied by a decrease in plasticity. The organization and performance of cold-rolled products are uniform, with good mechanical properties and the ability to withstand reprocessing; the product has high dimensional accuracy, good surface quality and plate shape; by controlling different processing rates or coordinating with finished product heat treatment, products in various states can be obtained; cold rolling can produce aluminum veneer thin strips or foils that cannot be rolled out by hot rolling. 3
Since cold rolling of aluminum veneer has the above characteristics, it is a better choice to choose cold rolling of aluminum veneer in occasions with high precision requirements or high shape requirements. In addition, cold rolling can also be used for some situations where hot rolling of aluminum veneer cannot be handled well. Therefore, for specific applications such as hyperbolic aluminum veneer, the choice of hot rolling or cold rolling plate manufacturing needs to be determined according to the specific use environment and requirements.
