Quality Control

Our aluminum products are manufactured and supplied under a rigorous quality management system. We provide material tailored to various industry standards, including ASTM specifications for wrought and cast alloys, as well as high-purity grades for specialized applications. Certificates of Analysis (COA) detailing lot-specific purity, alloy composition, and physical properties are available for all shipments to ensure traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. For powder or finely divided forms, store under an inert atmosphere (e.g., argon or nitrogen) in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, halogens, and strong oxidizers. Keep away from heat, sparks, and open flame. Bulk metal forms should be stored in a dry environment to prevent surface oxidation.
