strong powerful field coil magnet neodymium magnets speaker 

Neodymium disc magnets are strong Rare-Earth magnets, circular in shape. Neodymium magnets are the most powerful magnets commercially available today with magnetic properties that far exceed those of other permanent magnet materials. Due to their high magnetic strength, neodymium ring magnets have replaced other magnetic materials in order to make a design smaller while achieving the same result.

Neodymium Magnets in Assorted Sizes and Shapes
We stock licensed neodymium magnets in different lengths, OD diameters, finishes and premium grades. Finishing options for NdFeB magnets are uncoated, with a triple- coating (Ni-Cu-Ni) nickel finish. Not all of our magnets are shown on this website so please contact us today if you don't see what you are looking for.

Neodymium Magnets, also known as Round Base, Round Cup, Cup or RB magnets, are powerful mounting magnets, built with neodymium magnets in a steel cup with a 90° countersunk hole on the working surface to accommodate a standard flat-head screw. The screw head sits flush or slightly below the surface when affixed to your product.

The magnetic holding force is focused on the working surface and is significantly stronger than an individual magnet. The non-working surface is very little or no magnetic force.

1. Grades 

      - The grades like N48-N52 could meet your requirement on strong power

      - Standard one like N35 or N38 is okay for your normal applications

      - If you have requirement on the working temperature, please note it.

2.Shapes and Sizes           

 3. Coatings / Platings                   

Choices:  Zinc, Nickel,NiCuNi,gold, silver, epoxy, parylene, etc.

4. The production process

Packaging:

usually inner carton -→  outer box (singer layer and double layer) -→ pallet and can be packaged per your requests.

+By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.

+By Sea: If the goods are will be shipped by sea, we will place a pallet on the bottom of cartons.

Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.
a: The weight is under 40Kgs, we recommend to send them in shielding boxes to you by Express.
b: The weight is between 40Kgs-100Kgs, it can be sent by Express or Air.
c: The weight is over 100Kgs, we recommend to send them by Ocean.
