Quality Control

Our Copper is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and compliance with international standards such as ASTM, ISO, and JIS. We provide comprehensive quality assurance, including detailed Certificates of Analysis (COA) that report key parameters like purity, trace metal impurities, and physical form specifications. For specialized applications, we can supply grades meeting specific requirements for high-purity electronics (e.g., 5N, 6N) or metallurgical uses.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its tendency to be easily oxidized (store under inert atmosphere), it is recommended to store high-purity or finely divided forms (e.g., powder) under an inert gas such as argon or nitrogen to prevent surface oxidation. Maintain storage temperatures between 15-25°C. Keep away from strong acids and oxidizing agents.
