Aluminium alloy ingots for castings

This document establishes technical specifications for aluminum alloy ingots specifically designated for casting applications. The content outlines the classification system based on chemical composition, defining the permissible ranges for various alloying elements and impurities. It details the requirements for the physical structure and surface quality of the ingots to ensure suitability for subsequent molding processes. Procedures for sampling, testing, and inspection are provided to verify conformity with the defined criteria, covering aspects such as chemical analysis methods and visual examination protocols. The standard addresses the consistency of manufacturing practices to guarantee that the material performs reliably in industrial casting operations. It serves as a foundational reference for producers and users in the metallurgical sector to maintain uniform quality standards across transactions. The text specifies the conditions under which the materials should be stored and transported to prevent degradation prior to use. Adherence to these guidelines facilitates interoperability and quality assurance within the broader supply chain of aluminum alloy products.
