Quality Control

Our Platinum Rhodium alloys are manufactured under stringent quality management systems. Each batch is analyzed to confirm precise composition, purity, and physical properties, ensuring compliance with relevant industrial and customer-specific specifications. A comprehensive Certificate of Analysis (COA) detailing assay results, trace metal analysis, and physical characteristics is provided with every shipment.

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 and strong oxidizing agents. For long-term storage of fine powders, an inert atmosphere is recommended to prevent surface oxidation.
