Metal stamping is a metalworking process used to form various parts and products from sheet metal. It accommodates a wide range of materials, including aluminum.
Aluminum is highly suitable for stamping operations due to its strength and workability. Stamped aluminum components find application in nearly every industry, including aerospace, automotive, electronics, marine, medical, and more. Below we provide an overview of the aluminum stamping process, including typical materials employed and the properties they exhibit.
For stamping operations, pure aluminum is often alloyed with other metals to add or enhance certain material properties to improve the performance of the end product. Typical alloying materials include copper, iron, magnesium, manganese, silicon, and zinc. Each alloy is assigned a unique four-digit number, the first digit of which is determined by the primary alloying element. For example:
The four-digit number may also include a letter tagged onto the end. This letter is indicative of the alloy’s temper designation. For example, fabricated is represented by F, annealed is represented by O, strain hardened is represented by H, solution heat-treated is represented by W, and heat treated (not applicable to F, O, or H designations) is represented by T.
Some of the most commonly used aluminum alloys in metal stamping operations are:
As indicated above, aluminum alloys may demonstrate different properties depending on the exact composition. However, there are some shared properties among the material group, including:
