Magnet

Industry Overview

The magnet industry covers the production of permanent magnetic materials (such as NdFeB and SmCo) and soft magnetic materials (such as ferrites), serving as a critical upstream sector for strategic industries including new energy vehicles, wind power, energy-efficient appliances, and electronic information. Core processes such as sintering, atmosphere protection, and jet milling rely heavily on high-purity nitrogen. Nitrogen purity and supply stability directly affect magnetic properties, consistency, and finished product yield — making them key determinants of product quality.

Solution

Fengyun Fluid delivers a full-process high-purity nitrogen supply system purpose-built for the magnet industry. Based on cryogenic air separation technology, the system continuously supplies nitrogen at 99.999%+ purity for critical processes such as jet milling and sintering furnace atmosphere protection. The solution spans the entire lifecycle — from air separation equipment design and manufacturing to on-site installation, commissioning, and long-term operation and maintenance — and can integrate with an IoT smart platform to enable unattended operation, ensuring consistent gas purity, pressure, and flow throughout the magnet production process.
