Quality Control

Our Samarium Cobalt is produced under stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Material specifications are rigorously verified through advanced analytical techniques including X-ray fluorescence (XRF), inductively coupled plasma (ICP) analysis, and magnetic property testing. A Certificate of Analysis (COA) detailing lot-specific purity, composition, and magnetic 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). As a fine powder or solid alloy, it should be kept away from strong magnetic fields during storage to prevent unintended magnetization or demagnetization. Keep container sealed when not in use to minimize exposure to atmospheric moisture and contaminants.
