Technical regulation EN 1780-1: classification of aluminum systems
The EN 1780-1 standard defines a unified five-digit numerical coding system for aluminum alloys and master alloys. This methodology serves as an industry benchmark for the classification of ingots intended for remelting and foundry production, covering the entire spectrum of engineering tasks, including critical components for the aerospace industry.
A separate classification system, regulated by the EN 576 standard, is applied to unalloyed aluminum. The use of standardized codes allows EV Group China engineers to ensure precision in deliveries and compliance of materials with specified physical and mechanical characteristics.
Alternative symbolic designations of chemical compositions are based on the provisions of EN 1780-2, and the rules for the correct documentation of the chemical composition of alloys during labeling strictly follow the requirements of the EN 1780-3 standard.
