The core material of aluminum signs is aluminum or aluminum alloy. The specific grade is chosen based on the application scenario, process requirements, and cost factors.
Aluminum signage is a product made primarily of aluminum or aluminum alloys, used for identification signs, nameplates, or other signage. According to publicly available information, common materials include:
Pure aluminum sheet: such as the 1050 and 1060 series, with aluminum contents ≥99.5% and ≥99.6% respectively. It has good corrosion resistance and formability, suitable for general indoor or light outdoor environments.
Aluminum alloy sheet: such as 3003 and 6061, with added manganese, magnesium, silicon, etc., to improve strength and weather resistance, making it more suitable for traffic signs, machinery, and other applications requiring higher mechanical performance.
