For a wide range of industrial, commercial, and prototyping applications, N35 Neodymium Block Square Magnets represent the sweet spot between magnetic strength and component cost. The N35 grade offers a typical maximum energy product of 33‑35 MGOe-enough for holding, sensing, and fixturing tasks without the premium price of higher grades like N42 or N48. Our block square magnets are produced from 100% virgin rare‑earth materials (purity ≥95%) with strict control over alloy composition and sintering parameters. The result is a consistent remanence of 1.17‑1.21 T and a coercivity that resists accidental demagnetization. Each block is precision ground on all six faces, delivering squareness within 0.05mm and sharp but safe edges. Whether you need a single prototype or a million pieces, our vertically integrated factory can supply N35 neodymium block square magnets in standard and custom sizes, with fast lead times and full traceability.
N35 Neodymium Block Square Magnets – Simple Geometry, Solid Performance
Key Features of Our N35 Block Squares
Dimensional Accuracy
Our multi‑axis grinding centers hold length, width, and thickness to ±0.03mm as standard. For demanding assemblies, we can achieve ±0.01mm. Every block is inspected with vision systems or CMM before packing.
Flexible Coating Options
Standard Ni‑Cu‑Ni triple plating (5‑7μm per layer) offers salt spray resistance up to 72 hours. Choose epoxy for electrical insulation, gold for medical devices, or rubber for anti‑skid surfaces.
Full Size Range
From 2×2×1 mm up to 100×100×50 mm, with any rectangular ratio. We also offer chamfered or rounded corners on request. No tooling fees for standard dimensions.

Built on 20+ Years of Magnetic Manufacturing
We don't just resell magnets-we make them. Our factory controls the entire chain: alloy melting, jet milling, pressing, sintering, heat treatment, grinding, coating, and magnetization. This vertical integration means we can guarantee raw material purity (≥95% virgin neodymium), traceability, and consistent magnetic output. Every batch of N35 neodymium block square magnets undergoes flux testing with a Helmholtz coil, dimensional inspection, and coating adhesion verification (cross‑cut test). Salt‑spray chambers run periodic checks to validate corrosion resistance. Our IATF 16949 and ISO 9001 systems ensure that your production line receives the same quality, shipment after shipment.
IATF 16949:2016 ISO 9001:2015 RoHS & REACH Material Test Cert.
Packaging – Ready for Global Shipment
Each magnet is separated by foam or placed in 8‑cell anti‑shock inner boxes to prevent edge chipping. Outer cartons are reinforced with corner protectors and clearly labeled. We offer free samples for evaluation, small batch orders for prototyping, and container loads for high‑volume production. Standard sizes ship within 7 days; custom dimensions typically 12‑15 days.
