Neodymium disc magnets, 30 x 3 mm, with Ni-Cu-Ni coating and double-sided adhesive. Sold as a pack of four, these permanent rare earth magnets suit a wide range of mounting and craft applications.
Reliable holding power, with neodymium composition
Made from neodymium, described in the listing as the world's strongest magnetic element, the discs generate concentrated magnetic fields that deliver an 8 KG pull rating. The small disc shape focuses force across the contact area for secure attachment to ferrous surfaces.
Strong holding capacity keeps notes, pictures and small tools in place, and user feedback confirms secure phone-holding on car mounts.
Corrosion-resistant finish, with Ni-Cu-Ni coating
A nickel-copper-nickel triple-layer coating creates a smooth silver finish and forms a barrier against corrosion and surface wear. The plating also reduces the risk of scratches during handling.
Magnets retain a neat appearance on display and withstand everyday handling better than uncoated alternatives.
Versatile mounting options, with double-sided adhesive and compact size
Each disc measures 30 x 3 mm, equivalent to about 1.18 inches by 0.12 inches, making the magnets compact and portable. Double-sided adhesive pads allow fixing to smooth, non-porous surfaces without drilling.
Small discs fit tight spaces such as frames and jars, while adhesive backing enables quick, low-impact mounting for DIY and craft projects.
