مغناطيس حلقة النيوديميوم المغناطيسي

BMAG Neodymium Ring Magnets represent the gold standard in high-flux density for circular geometries. Sintered from a high-performance alloy of Neodymium, Iron, and Boron, these magnets deliver an extraordinary BHmax (Maximum Energy Product) in a compact, hollow-center form factor. The ring geometry is specifically engineered to allow for mechanical passage or center-axis mounting, providing a balanced magnetic field that radiates symmetrically around the central void.

These magnets are manufactured through a rigorous powder metallurgy process, ensuring uniform grain alignment for peak magnetic anisotropy. Available in grades ranging from N33 to N55, they offer exceptional remanence (Br) and coercive force (Hcj). To counteract the natural oxidization tendencies of rare earth materials, each ring is shielded with a high-quality Ni-Cu-Ni (Nickel-Copper-Nickel) triple-layer coating. This creates a resilient, silver-bright finish that resists humidity and physical wear. Each piece is precision-ground to meet tight dimensional tolerances, ensuring a perfect fit for assemblies requiring high-torque or high-holding forces.
