Introduction

Introducing our high-performance Sintered SmCo Magnets, the ultimate solution for demanding applications that require stable and robust magnetic properties even in extreme conditions. Manufactured through a precise powder metallurgy process, these magnets offer exceptional performance in high-temperature environments, making them indispensable in advanced technological applications.

What are Sintered SmCo Magnets?

Sintered SmCo magnets, also known as sintered samarium cobalt magnets, are permanent magnets with unique properties derived from their specialized crystal structures. These magnets are available in two primary types based on their crystal structure: hexagonal (1:5 type) and rhombohedral (2:17 type). Each type offers distinct magnetic characteristics tailored for various high-performance applications.

Manufacturing Process

Our sintered SmCo magnets are produced using a sophisticated powder metallurgy process. This involves mixing fine powders of samarium, cobalt, and other rare earth elements, followed by pressing, sintering, and magnetizing. This method ensures a highly dense and uniform magnet with superior magnetic performance and stability.

Composition

The primary elements in sintered SmCo magnets are samarium and cobalt. However, we enhance specific properties by substituting portions of these elements with other rare earth elements like praseodymium, cerium, gadolinium, and erbium. Additionally, a portion of cobalt can be replaced with iron to increase the saturation magnetization, providing stronger magnetic fields for your applications.
