Rigorous Testing, Complete Traceability, International Standards
From raw material selection through electrochemical deposition, washing, reduction, and classification, consistent powder properties are ensured through scientific control and statistical process monitoring.
Every batch undergoes comprehensive testing per Indian Standards (IS) and ASTM equivalents. Certificate of Analysis accompanies every shipment, providing complete transparency and traceability.
