Various types of permanent magnet products

(2) various types of permanent magnets and performance parameters

bonded NdFeB Magnet

Plastic Bonded Magnets grades currently no uniform, different manufacturers may use different product brands, the following examples to introduce their grades and performance parameters. The following table shows the bonding neodymium iron boron grades and performance parameters, which letters and numbers are as follows.

BNP: manufacturer code

Number: Maximum energy product (BH) max, in units of MGOe;

SR: high coercivity

H: high intrinsic coercivity;

L: Magnetic performance is low.

Smco magnets currently no uniform grade that the production company's representation is also different, the following table lists one of the methods that the brand performance table, as an example to introduce. The following two tables list the grades of SmCo5 and Sm2Co17, respectively. The following letters and numbers represent the meaning of the letter as follows:

RECo5: SmCo5 magnet;

RE2Co17: Sm2Co17 magnet;

Number: The value of the maximum energy product (BH) max, in units of MGOe;

L: low coercivity;

M: Medium coercivity;

H: High coercivity.
