Product Specifcations
Our magnetic hooks are made from high-grade N52 sintered NdFeB, providing excellent magnetic flux density and stable performance. The sintering process aligns the crystalline structure of the rare-earth elements, giving the hooks strong vertical pull forces. These magnets maintain consistent performance even after long-term use.

| Material | Sintered NdFeB + A3 Precision Steel |
| Tolerance | ±0.05mm |
| Coating | Ni-Cu-Ni (Nickel) Plating |
Precision A3 Steel Housing
The hooks are encased in precision-machined A3 steel, which concentrates the magnetic field and protects the brittle NdFeB core. The flat base maximizes contact with ferrous surfaces, allowing the hook to reach its rated load capacity without slipping.
The steel casing also prevents cracking or chipping during accidental impacts.
Durable Triple-Layer Ni-Cu-Ni Plating
Each hook is plated with a Ni-Cu-Ni (Nickel-Copper-Nickel) coating to resist corrosion and wear. This plating achieves a smooth, mirror-like finish and allows the hooks to withstand humid environments. Standard hooks with this coating pass a 72-hour salt spray test (SST).
The nickel layers also reduce scratching on the surfaces where the hooks are attached.
Versatile Applications
These magnetic hooks are suitable for industrial warehouses, workshops, kitchens, and homes. They can organize tools, equipment, or household items without drilling or leaving marks.
The removable hook design allows interchangeable attachments such as J-hooks, eyelets, or swivels, depending on the task.
Zero-damage relocation makes them ideal for rented spaces, cruise cabins, or school lockers.
Quality Control & Safety Compliance
Every batch is fully inspected with digital pull-force meters to ensure accurate rated strength.
The hooks comply with RoHS and REACH standards and are packaged to prevent interference with electronic devices during transport.
By choosing these hooks, customers get reliable performance and safe, long-lasting use.
