There are many factors that determine the delivery time of magnets, which are related to the performance, size, and shape of the products.

①The representation methods of the grades are different: SmCo5 is generally represented by YX; Sm2Co17 is generally represented by YXG.

②Different components: the main components of SmCo5 are samarium, cobalt, praseodymium, or just pure samarium cobalt; the main components of Sm2Co17 are samarium, cobalt, copper, iron and zirconium.

③Different physical properties: For example, the maximum working temperature of SmCo5 is 250℃, the maximum working temperature of Sm2Co17 is 350℃. The mechanical and physical properties of SmCo5 are better than those of Sm2Co17, and it is slightly easier to process, and Sm2Co17 is more brittle.
