Alloy Tempering Conditions
The 'H' temper designation indicates that the material has undergone strain hardening with the second digit specified (in this case, 12) indicating the specific strength and IDs for intermediate levels of resistance to deformation.
- H12 specifies that dealing operations were performed and moderate recovery of strength has taken place whilst retaining some of the stamping characteristics – the solution enhances both performance and manufacturability.
1100 H12 polished aluminum sheets combine high efficiency, versatile applications, and aesthetic appeal into a single product. They contain excellent mechanical properties, ensuring consistent reliability across multiple operational environments. Widely usable in various industries, from architecture to automotive production, these polished sheets effectively balance both functionality and design aesthetics.
By the inherent material properties, chemical composition, and practical uses, engineers and manufacturers can make informed decisions when selecting aluminum sheets for their specific applications.
