How is the quality of Ferro Silicon Nitride ensured, and does ZhenAn provide third-party testing?

Quality assurance is a core priority at ZhenAn​ for all Ferro Silicon Nitride (FeSiN) products. We implement a strict quality control system​ that covers raw material selection, production parameters, particle sizing, and final product inspection. Every batch of FeSiN is tested for key metrics such as chemical composition (Fe, Si, N content), impurity levels, particle size distribution, and physical consistency.

To further enhance transparency and credibility, ZhenAn supports third-party testing​ through internationally accredited laboratories. This allows our customers to independently verify the purity, nitrogen release potential, and metallurgical performance​ of our FeSiN products. Such validation is crucial for companies in aerospace, automotive, and precision casting sectors, where material reliability directly impacts performance and safety.

Our standard 10-50mm aggregates or lumps go through rigorous in-house testing before shipment, and we are fully prepared to coordinate with your preferred testing agency if required. In addition, we provide detailed certificates of analysis (COA)​ with every order and offer free samples​ for preliminary evaluation.

When you source FeSiN from ZhenAn, you're not just buying a product-you're gaining a trusted technical partner​ committed to quality, innovation, and performance. Let us help you achieve consistent results in your metallurgical processes.
