Hot Rolled vs Cast-Rolled Aluminum: Process, Performance and Application Comparison
Aluminum sheets, coils and foils are widely applied in packaging, construction, transportation, electronics and food container industries. Hot rolling and cast rolling are the two mainstream production technologies for rolled aluminum products. They differ greatly in manufacturing flow, internal microstructure, mechanical properties, production cost and applicable scenarios. Many common aluminum alloys including 1xxx, 3xxx and 8xxx series can be processed by both methods. This article makes a comprehensive comparison between the two processes to help purchasers, engineers and manufacturers select appropriate aluminum materials for different projects.
