Aluminium, magnesium and their alloys; Temper designations

This standard establishes a systematic approach for designating status codes related to aluminum, magnesium, and their corresponding alloys. The primary objective is to provide a uniform method for classifying the material state based on processing history and mechanical properties. By implementing specific symbols and numerical codes, the document facilitates clear communication among manufacturers, engineers, and suppliers regarding the condition of these non-ferrous materials. This classification covers various temper states achieved through processes such as cold working, annealing, heat treatment, or combinations thereof. The adoption of these codes ensures consistency in technical documentation, manufacturing specifications, and quality control procedures across international industrial sectors. Through this standardized nomenclature, the need for lengthy textual descriptions is minimized, thereby reducing ambiguity in product orders and engineering drawings. The system applies specifically to wrought products and castings derived from the mentioned base metals, offering a structured framework essential for global trade and technical interoperability in metallurgy and engineering applications.
