Technical Specification of the EN 1774 Standard: Zinc and Zinc Alloys
The international standard EN 1774 establishes strict regulations for the classification, chemical composition, labeling methods, and technical requirements for zinc alloys. The document covers products in the form of ingots, molten alloys, and semi-finished products intended for various die-casting and centrifugal casting methods.
EV Group China specialists use this standard to ensure quality control in the supply of raw materials for foundries. Compliance with EN 1774 guarantees the predictability of the physical and mechanical properties of castings and the stability of technological processes at the customer’s facilities.
Areas of Application and Requirements
The standard is fundamental to the metallurgical industry for the production of critical parts made from zinc alloys. It defines the permissible concentrations of alloying elements and impurities, which is critical for preventing intercrystalline corrosion and ensuring the required dimensional accuracy of finished products.
When ordering metal products from EV Group China, you receive certified alloys that fully comply with the current requirements of EN 1774, which eliminates the risk of defects during subsequent mechanical and thermal processing.
