 Rubber Coated magnetic systems with neodymium magnets for demanding tasks. The rubber-coated adhesive surface protects the metal from scratches and grounds for detention increases the pushing force. The neodymium magnets are arranged alternately pole and thus increase the adhesive force. As material for the rubber sheath Santoprene was used. They can be mounted with different exposures (threaded stud, threaded socket, female threaded, hole or depression).
We can supply Custom-made Rubber coated magnetic systems (Other sizes, shapes and grades) may be available by your requirements.

Q1. How long would I get your feedback?

A:  We will reply your questions or inquiry within 24 hours and we service 7 days per week.


Q2. Can you supply custom magnets?

A:  Sure, we offer customized magnets. Virtually any shape of Neodymium magnet can be made to your requirements and design.


Q3. Can you add my logo on your products and do you offer OEM or ODM service?

A:  Sure, we can add your logo on the products as your requirements and OEM & ODM service are warmly welcome!


Q4. What package do you use for the products?

A:  We have export standard foam-filled cartons. Besides we also offer tailored packaging per customer request. Our packages appropriate to both air and sea shipment available.


Q5. What’s the transportation method of Neodymium magnet?

A:  All shipping methods on offer: courier (TNT, DHL, FedEx, UPS), air or sea, with transit tracking regardless. Shipper or freight forwarder may be appointed by either purchaser or Besten magnet.


Q6. Do you provide samples?

A:  Sure, we offer samples for free if we have magnet in stock.


Q7. How do you control your quality?
A:We have been monitoring from raw materials to the whole production processes and uses various advanced testing instruments to ensure the quality stability before the raw material is put in storage. Our QC Department ensures an ongoing development and maintenance of high quality standards by strictly complying with our Quality Management System as well as all applicable regulations and customer requirements for all finished products. Automatic Production lines were put into operation to raise reliability of products Performance to improve production efficiency.


 Q8. What are Neodymium magnets? 

A:  Neodymium magnets are a member of the rare earth magnet family. They are also called "rare earth magnets" because neodymium is a member of the "rare earth" elements on the periodic table. Neodymium magnets are the strongest of the rare earth magnets and are the strongest permanent magnets in the world.


Q9. What's the Grade of a magnet ?

A:  Neodymium Permanent Magnet are graded according to their maximum energy product of the material that the magnet is made from. It relates to the magnetic flux output per unit volume. Higher values indicate stronger magnets and range from N35 up to N52.  and M, H, SH, UH, EH, AH series, can be customized into a wide range of shapes and sizes with precise tolerances. Multiple choices of coatings and magnetization orientations can meet specific customer requirements. Letters following the grade indicate maximum working temperatures (often the Curie temperature), which range from M (up to 100 °C) to EH (200 °C) to AH (230 °C)


Q10. What’s the working temperature for various grades of Neodymium magnets?

 A:  Neodymium Iron Boron magnets are sensitive to heat. If a magnet heated above its maximum operating temperature, the magnet will permanently lose a fraction of its magnetic strength. If they are heated above their Curie temperature, they will lose all of their magnetic properties. Different grades of neodymium magnets have different maximum operating temperatures.



Q11. What is the difference between the different plating?

A:  Choosing different plating does not affect the magnetic strength or performance of the magnet, except for our Plastic and Rubber Coated Magnets. The preferred coating is dictated by preference or intended application. More detailed specifications can be found on our Specs page. 
• Nickel is the most common choice for plating neodymium magnets. It is actually a triple plating of nickel-copper-nickel. It has a shiny silver finish and has good resistance to corrosion in many applications. It is not waterproof. 
• Black nickel has a shiny appearance in a charcoal or gunmetal color. A black dye is added to the final nickel plating process of the triple plating of nickel-copper-black nickel. NOTE: It does not appear completely black like epoxy coatings. It is also still shiny, much like plain nickel plated magnets. 
• Zinc has a dull gray/bluish finish, that is more susceptible to corrosion than nickel. Zinc can leave a black residue on hands and other items. 
• Epoxy is basically a plastic coating that is more corrosion resistant as long as the coating is intact. It is easily scratched. From our experience, it is the least durable of the available coatings. 
• Gold plating is applied over the top of standard nickel plating. Gold plated magnets have the same characteristics as nickel plated ones, but with a gold finish.

• Aluminum plating is a New plating technology applied in Neodymium magnet industry. It’s a kind of protection film with fine integral performance, smoother that mechanical galvanizing layer, without porosity, with high impact resistance and it’s corrosion resistance was better than any of other plating layers. Its SS testing time can reach 800 hours.
