Quality Control

Our brass alloys are produced under strict quality management protocols to ensure consistent composition, mechanical properties, and dimensional accuracy. We adhere to relevant international standards such as ASTM, ISO, and DIN. Material certifications and detailed Certificates of Analysis (COA) confirming chemical composition and physical properties are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids, ammonia, and other corrosive chemicals to prevent tarnishing or surface degradation. For long-term storage, ensure the environment has low humidity to minimize oxidation.
