Grade Comparisons
Compare specific NdFeB grades on BHmax, temperature rating, coercivity, and cost.
N48 vs N52
N48 vs N52
N52 delivers 10–15% higher energy product than N48, but at meaningfully lower temperature rating. Here is when each is the right choice.
N42 vs N42SH
N42 vs N42SH
Same BHmax, very different thermal envelope. N42 is room-temperature; N42SH handles continuous 150°C — the working grade for EV and robotics motors.
N45SH vs N48SH
N45SH vs N48SH
Both rated to 150°C continuous, but N48SH delivers ~7% more BHmax. For humanoid robotics and premium EV motors, the choice hinges on whether 7% flux is worth 10–15% cost.
Material Comparisons
Compare magnet materials — NdFeB, SmCo, and NdFeB variants (sintered, bonded).
NdFeB vs SmCo
NdFeB (Neodymium) vs SmCo (Samarium-Cobalt)
The two commercial rare earth magnet materials. NdFeB wins on energy density below 180°C; SmCo wins on temperature stability above 200°C and intrinsic corrosion resistance.
Sintered NdFeB vs Bonded NdFeB
Sintered NdFeB vs Bonded NdFeB
Sintered NdFeB is the high-performance standard. Bonded NdFeB is a polymer-matrix variant with lower BHmax but enables near-net-shape manufacturing and complex geometries.
Coating Comparisons
Compare NdFeB coating systems on corrosion resistance, durability, and cost.
Architecture Comparisons
Compare magnet architectures — radial multi-pole rings, arc segments, and alternatives.
Sourcing Comparisons
Compare supply-chain strategies — factory-direct vs trading, geographic sourcing options.
Factory Direct vs Trading Company
Factory Direct Supplier vs Trading Company
Buying directly from the manufacturer vs routing through a trading intermediary. The right structure depends on volume, technical complexity, and documentation needs.
China vs Japan NdFeB Suppliers
Chinese NdFeB Supplier vs Japanese NdFeB Supplier
China dominates global NdFeB production by volume; Japanese suppliers retain a niche in premium grades. The gap has narrowed substantially since 2020.
Certification Comparisons
Compare quality management system standards relevant to magnet supplier qualification.
