Block Neodymium Magnet Advantages
1.Material
Sintered Neodymium magnets are made from metallic Nd, Fe, B, and other trace metal elements through smelting, milling, pressing, sintering, and follow-up procedures. They are a kind of energy store with a high energy density. Sintered NdFeB magnets can efficiently realize the mutual conversion of energy and information, and their energy will not be lost.
2.World's most precise tolerance
The tolerances of magnets can be controlled within ±0.05mm or even more, if you have a special requirement for tolerance, please feel free to let us know.
3.Coating / Plating
If the block neodymium magnets are not electroplated, it will rusted and corroded easily under moist air environment. Ni-Cu-Ni is the most common coating for neodymium magnet. It has a good resistance to corrosion.
Other options: Zinc (Zn) , Black Epoxy, Rubber, Gold, Silver, etc.
4.Magnetic Direction: Axial
Block magnets are defined by three dimensions: Length, Width and Thickness.
The regular magnetic direction of block magnet are magnetized through the length, width, or thickness.
Packing & Shipping
We will use magnetically isolated packaging that can be used for Air transport, and use standard export cartons and pallets for Sea transport.
