The correlation between alphanumeric and numeric temper designations represents a critical aspect of aluminum alloy specification and quality control. These designation systems provide standardized methods for communicating material conditions and expected properties throughout the supply chain.
Alphanumeric designations typically utilize letter codes combined with numerical values to indicate specific heat treatment conditions, work hardening levels, and aging processes. Numeric designations offer alternative coding systems that may align with different international standards or legacy specification systems.
Cross-reference tables eliminate confusion and potential errors that could arise from misinterpretation of temper designations. They serve as essential tools for procurement professionals, quality engineers, and production managers who must ensure material compatibility across different specification systems.
The aluminum sheets, strips, and wires covered by DIN 1788 and DIN 1790 standards find applications across diverse industrial sectors. In the automotive industry, thin aluminum sheets provide lightweight solutions for body panels and structural components while maintaining excellent corrosion resistance and formability.
