Quality Control

Our Aluminium/Copper Alloy Powder is manufactured under stringent quality management systems. Each batch undergoes rigorous testing for critical parameters including particle size distribution (PSD), chemical composition, oxygen content, and flow characteristics to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We adhere to relevant ISO standards and can support customer-specific quality audits.

Storage

Preserve in a tightly closed container, protected from light. Due to its nature of being easily oxidized, this powder must be stored under an inert atmosphere (e.g., argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 15-25°C. Keep away from sources of ignition, heat, and incompatible materials such as strong oxidizers.
