Coating: NiCuNi, Zinc (Zn), or Epoxy anti-corrosion coating
Grades: N35 to N55 (including M, H, SH, UH, AH, RH, TH)
Maximum Dimensions:

Large Neodymium Block Magnets: Up to 350mm in length (e.g., 350x350x60mm, axially magnetized)
Large Neodymium Ring Magnets: Up to D300mm in diameter (e.g., D300xd200x60mm, axially magnetized)
Large Neodymium Arc Magnets: Up to 350mm in length
Large Neodymium Disc Magnets: Up to D300mm in diameter (e.g., D300x60mm, axially magnetized)
MOQ: 300 kg
Lead Time: Approximately 30 to 60 days, depending on order quantity

Applications:

Widely utilized in large-scale industrial applications, including large fans, motors, generators, MRI systems, magnetic separators, and large robots.

Production and Delivery:

Packaging:
- Air Shipment: Requires specialized air-safe packaging for magnetized magnets, significantly increasing gross weight (1.5–2 times the net weight), leading to higher shipping costs.
- Sea Shipment: More cost-effective with lower packing and shipping costs, though delivery times are longer.
Custom Packaging: Available to meet specific customer requirements for safe transport.

Quality and Compliance:

Manufactured under stringent quality controls, fully compliant with RoHS standards.

Safety Note:

Large neodymium magnets (N30, N35, N52, etc.) are extremely powerful and potentially hazardous. Ensure proper handling experience to manage risks safely.
