Advanced high-coercivity, high-remanence NdFeB magnets optimized for Australia's demanding heavy industries.
Australia’s rapid pivot toward clean energy production, automation of deep-pit mineral extraction, and local high-tech defense manufacture has catalyzed a steep increase in demand for premium-grade rare earth magnets. Finding a reliable neodymium magnet supplier that satisfies the strict mechanical tolerances and environmental parameters required in Australia's hot, demanding environments is a major procurement challenge.
As direct-drive offshore wind generators and commercial electric vehicle motors push thermal limits, standard magnetic grades are no longer sufficient. High-temperature applications require advanced grades of sintered Neodymium-Iron-Boron (NdFeB) such as EH, AH, and SH, which boast high intrinsic coercivity (Hcj) and resist irreversible demagnetization.
For procurement officers and manufacturing engineers in Melbourne, Sydney, Perth, and Brisbane, sourcing directly from high-capacity factories with integrated supply chains is critical. This secures the required thermal-resistant grades, provides access to advanced coatings like nickel-copper-nickel (NiCuNi) and epoxy, and helps manage costs amid raw material market volatility.
Zhejiang Laysun Magnetics Ltd. is a national high-tech manufacturer specializing in rare earth NdFeB permanent magnets. Operating from a state-of-the-art 100,000 m² factory in Sichuan and headquartered in Hangzhou, China, our 300+ professionals produce up to 5,000 tons of high-performance rare earth magnets annually.
By controlling the entire process from alloy smelting and hydrogen decrepitation to sintering, finishing, and coating, we maintain consistent physical properties across production runs. This is critical for Australian clients in precision manufacturing, defense aviation, and heavy mineral separation who require strict batch-to-batch consistency.

How advanced technology, automated quality control, and innovative material science reduce procurement costs for Australian buyers.
By diffusing Dysprosium (Dy) or Terbium (Tb) through the crystal grain boundaries instead of alloying them throughout the entire magnet body, we significantly reduce the usage of expensive heavy rare earths. This maintains high temperature resistance (up to AH/EH grades) while lowering costs for our partners.
Oxygen levels must be strictly managed when producing high-grade magnets. Our oxygen-free production lines use automated hydrogen decrepitation and vacuum sintering furnaces. This limits oxygen content to less than 1000ppm, reducing magnet degradation in demanding industrial settings.
Australia’s marine and mining environments require robust surface protection. We offer specialized multilayer coatings, including marine-grade Zn plating, Epoxy resin (salt-spray test tested up to 1000+ hours), and Nickel-Copper-Nickel (Ni-Cu-Ni), to prevent moisture and salt corrosion.

Tailored NdFeB magnetic configurations designed for Australia's leading primary industries.
In the iron ore, coal, and lithium mines of Western Australia and Queensland, heavy-duty NdFeB block magnets are integrated into overhead magnetic separators. These blocks generate deep-reaching magnetic fields to extract tramp metals from raw materials on high-velocity conveyors, protecting expensive crushers and mills.
Large offshore and onshore wind farms along Australia’s southern coastline rely on NdFeB arc segments inside multi-megawatt direct-drive generators. These heavy turbines operate in coastal marine environments, requiring magnets with low weight-loss parameters and high thermal stability to ensure decades of maintenance-free service.
Australian logistics centers and deep-sea mineral processing facilities use smart automated guided vehicles (AGVs) and robotic cranes. High-torque servo motors powered by NdFeB block magnets ensure the power density, responsiveness, and positioning accuracy required in these automated environments.
We believe credentials and traceability are key to building reliable long-term partnerships. Zhejiang Laysun Magnetics maintains rigorous quality control procedures. Our manufacturing processes are certified to international automotive and environmental management system standards, including API 6D, API 607, CE, ISO9001, ISO14001, ISO18001, and IATF 16949.
Every shipment is backed by raw material analysis, demagnetization testing curves, salt-spray resistance documentation, and dimensional analysis reports. This ensures that every magnet delivered to Australia performs reliably in high-temperature or corrosive operating conditions.
A broad catalog of NdFeB configurations ready for direct shipment to Australia's industrial corridors.
Connecting state-of-the-art facilities directly with marine terminals and logistics hubs across Australia.
Establishing stable, high-capacity logistical networks between factories in China and distribution hubs in Western Australia, Victoria, New South Wales, and Queensland is critical to preventing project delays. We coordinate with international freight forwarders to offer air cargo, Less-than-Container Load (LCL), and Full Container Load (FCL) delivery options.
Additionally, all magnet packages are strictly shielded and packed in accordance with international transport regulations (specifically IATA rules for air transport and IMDG guidelines for maritime shipping) to ensure safe, delay-free clearance through Australian customs.
Our direct communication channels are supported by our headquarters in Hangzhou, China, enabling fast, responsive communication with Australian project managers across all time zones.
