Plating Characteristics
Plating Type | Overall Thickness | Salt Spray Test | Pressure Cooker Test |
NiCuNi (Nickel Copper Nickel) | 15-21 μm | 24 hours | 48 hours |
NiCu + Black Nickel | 15-21 μm | 24 hours | 48 hours |
NiCuNi + Epoxy | 20-28 μm | 48 hours | 72 hours |
NiCuNi + Gold | 16-23 μm | 36 hours | 72 hours |

Product FAQ
1. What are neodymium magnets? Are they the same as "rare earth"?
Neodymium magnets are a member of the rare earth magnet family. They are called "rare earth" 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.
2. What are neodymium magnets made from and how are they made?
Neodymium magnets are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets). The powdered mixture is pressed under great pressure into molds. The material is then sintered (heated under a vacuum), cooled, and then ground or sliced into the desired shape. Coatings are then applied if required. Finally, the blank magnets are magnetized by exposing them to a very powerful magnetic field in excess of 30 KOe.
3. What dose N35,N38,N40,N42,N45,N48,N50,N52 grade mean?
Neodymium magnets are graded by the maximum strength they can be magnetized to. The higher the number the stronger the magnet is, however the higher the number the more brittle the magnet becomes as well.
N52 Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world.
4. How is the strength of a magnet measured?
Gaussmeters are used to measure the magnetic field density at the surface of the magnet. This is referred to as the surface field and is measured in Gauss (or Tesla). Pull Force Testers are used to test the holding force of a magnet that is in contact with a flat steel plate. Pull forces are measured in pounds (or kilograms).
5. How is the pull force of each magnet determined?
All of the pull force values we specify have been tested in our laboratory. We test these magnets in two different configurations. Case 1 is the maximum pull force generated between a single magnet and a thick, ground, flat steel plate. Case 2 is the maximum pull force generated with a single magnet sandwiched between two thick, ground, flat steel plates. Case 3 is the maximum pull force generated on a magnet attracted to another magnet of the same type.
Magnets are widely used in many fields, such as Magnetic Toy, Mobile Cover, Sensor, Motor, VCM, Medical Equipment, Car Holder, Wind Turbine, Loud Speaker, Printer, Magnetic levitation, Ladies Bag, Gift Box Packing, Switch Boardand, Micro Phone and so on.
