Magnetic materials with maximum remanence and energy products are the strongest magnets. We are a professional strongest magnets manufacturer that can custom strongest neodymium magnets with full size and grade grange.We have many strongest small and giant neodymium magnet for sale,such as neodymium block magnets 100x100x50mm,100x100x20mm,90x90x20mm; neodymium disc magnets 100x20mm,90x20mm, 70x20mm, 10x5mm,10x2mm, 8x2mm.
Although the strongest neodymium magnets have magnetic performance advantages, they are not rust-proof, surface protection coating is very necessary for each strongest neodymium magnet, Here is the available surface treatment for the strongest neodymium magnets, and characteristics of each kind of coating.
Surface | Coating | Thickness (Microns) | Color | Resistance |
Passivation | 1 | Silver Grey | Temporary Protection | |
Nickel | Ni+Ni | 10-20 | Bright Silver | Excellent Against Humidity |
Ni+Cu+Ni | Good Against Salt Spray | |||
Zinc | Zn | 8-20 | Bright Blue | Excellent Against Salt Spray |

Caution is necessary for the strongest permanent magnets: The strongest permanent magnets(especially the large ones) are very dangerous, they would cause damage to your body and all electronic devices by improper operation. The strongest neodymium magnets with large dimensions and thin thickness are also fragile. Make sure to read the safety tips before handling and storing the neodymium strongest permanent magnets.
The strongest neodymium magnet grade: We have a full grade range of strongest neodymium magnets for sale, all available grades for powerful neodymium magnets are listed on the table, and there is also the maximum working temperature information for each grade. The strongest neodymium magnets grade that you can buy with any quantity is N52.
Neodymium Material Grade | Maximum Working Temp. | Curie Temp. |
N(N35,N38,N40,N42,N45,N48,N50,N52) | 176°F (80°C) | 590°F (310°C) |
N-M(N35M,N38M,N40M,N42M,N45M,N48M,N50M,N52M) | 212°F (100°C) | 644°F (340°C) |
N-H(N35H,N38H,N40H,N42H,N45H,N48H,N50H) | 248°F (120°C) | 644°F (340°C) |
N-SH(N35SH,N38SH,N40H,N42SH,N45SH,N48SH) | 302°F (150°C) | 644°F (340°C) |
N-UH(N28UH,N30UH,N33UH,N35UH,N38UH,N40UH,N42UH) | 356°F (180°C) | 662°F (350°C) |
N-EH(N28EH,N30EH,N33EH,N35EH,N38EH,N40EH) | 392°F (200°C) | 662°F (350°C) |
N-AH(N28AH,N33AH,N35AH,N38AH) | 428°F (230°C) | 662°F (350°C) |
From the point of view of magnetic materials, sintered NdFeB magnets are the strongest magnets in the world, and the neodymium magnets N52 are the strongest magnets on earth you can buy with any quantity.
