Rubber-coated neodymium magnets give great durability and high friction. The rubber plastic coating acts as a protection for the Neodymium Magnet against chipping and exposure to liquids. Rubber magnets are used in many holding applications. If you require a specific size, please contact us by using our online custom magnet quote form.

These Neodymium rubber coated magnets are high-strength rare earth magnets with a durable rubber plastic coating. They are especially suitable for applications where the surface might be easily scratched or damaged. The rubber plastic coating also protects the magnet against chipping and corrosion and provides superior slide resistance due to the friction between the rubber and steel surface to which the magnet is bonded. Manufacturers and industrial designers use rubber magnets for holding and fastening. They are well suited to aquariums, construction sites, and outdoor use. Some plastic-coated mounting magnets feature a central threaded hole (female thread) so you can attach them with a bolt, or a central threaded stud (male thread) so you can insert a hook or eye bolt. We also have rubber magnets with pre-drilled holes that can be screwed or nailed into place.

Black plastic coating prevents corrosion or chipping damage to the magnet and prevents damage to the surface you are mounting onto. The high friction of the coating offers greatly improved holding force on vertical surfaces.

If you need a soft surface on your magnet for mounting something on a fridge, car, or other surfaces you want to protect, don’t waste your time with Plastic-dip because it won’t work. NOTHING will stick to the surface of rare-earth (neodymium) magnets. The tape will protect temporarily but it will tear when you least expect it and damage will occur anyway.


What are rubber-coated magnets?
Rubber-coated magnets are strong permanent magnets, typically neodymium, encased in a protective layer of rubber. This coating enhances the magnet's durability and usability in various applications.
What are the advantages of rubber-coated magnets?
Surface Protection: The rubber coating prevents scratching and sliding on delicate surfaces, making them ideal for applications where surface protection is critical. Corrosion Resistance: The coating shields the magnet from moisture and chemical exposure, extending its usable life. Impact Resistance: Rubber helps absorb shocks and impacts, reducing the risk of the magnet chipping or breaking upon fall or collision. Increased Friction: The non-slip surface ensures the magnet stays firmly in place, even on vertical or sloped surfaces.
What applications are suitable for rubber-coated magnets?
Rubber-coated magnets are widely used in: Automotive: For attaching lights, signs, or equipment to vehicles without damaging paintwork. Marine: In boats and other watercraft for equipment mounting and attachment points, where corrosion resistance is essential. Home and Office: For hanging decorations, tools, or organizing cables without harming surfaces. Industrial: In manufacturing settings for holding or positioning parts during assembly or inspection.
Can rubber-coated magnets be used outdoors?
Yes, the rubber coating provides excellent protection against rain and UV exposure, making these magnets suitable for outdoor applications.
How strong are rubber-coated magnets?
The strength depends on the neodymium magnet's grade within the rubber coating. Neodymium magnets are among the strongest permanent magnets available, allowing rubber-coated magnets to hold substantial weight, even with their protective coating.
Are rubber-coated magnets customizable?
Rubber-coated magnets come in various shapes, sizes, and magnetization directions. While there are standard options available, manufacturers can often produce custom sizes and shapes to meet specific application requirements.
How do you install rubber-coated magnets?
Installation is generally straightforward, as the magnet can be directly placed on the desired surface. Some rubber-coated magnets come with additional mounting features, such as threaded holes, hooks, or loops, to aid in attachment.
How do you care for rubber-coated magnets?
Rubber-coated magnets require minimal maintenance. It's recommended to keep them clean and dry to ensure the longevity of the rubber coating. If used in saltwater or highly corrosive environments, rinsing with fresh water and drying after use can help prevent degradation of the rubber.
Can rubber-coated magnets be used on all surfaces?
While they are versatile, their effectiveness depends on the ferromagnetic properties of the contact surface. They adhere best to iron, cobalt, nickel, and their alloys. Non-metallic surfaces, or those with low magnetic permeability, will not hold the magnets effectively.
