Product Description
super strong N52 huge NdFeB Block Magnet is made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure. This material is currently the strongest type of permanent magnet in the world.
Nd-Fe-B permanent magnet is manufactured in a wide range of shapes, sizes and grades according customer's demand.
The main physical properties of super strong N52 huge NdFeB Block Magnet
Also becoming increasingly popular across a wide range of novelty products for markets
Nd-Fe-B permanent magnet is manufactured in a wide range of shapes, sizes and grades according customer's demand.
NdFeB has a very high energy product and coercivity, can pick up 660 times of own weight of heavy objects.
The advantage is high cost-effective, with good mechanical properties, easy cutting; according customer's demand to manufacture in a wide range of shapes, sizes and grades.
Also have high Br,high Hcj,high (BH)max,and high stability become the important material of the world.
The shortcoming is the low of the Curie temperature and the temperature characteristics, easy to rust, oxidation, Sintered NdFeB's surface is usually required for plating such as zinc, nickel, silver, gold, etc., can also be done phosphorus treatment or spray epoxy resin to slow down the oxidation rate.
Pls see the compare of the coating's results:
Commonly type of coating | Coating thickness(um) | Neutral salt spray test | ||||
dark Ni | Cu | Shine Ni | Total | |||
Single-layer Ni | 25 | 25 | 24h | normal | ||
Double-layer Ni | 12 | 10 | 25 | 72h | better | |
Dark Ni-Cu–shine Ni | 6.25 | 8.75 | 10 | 25 | 120h | excellent |
