AMSC supplies a full spectrum of magnet products.

The following are the brief descriptions of the different type of magnetic material and magnet assembly which will only give a basic introduction of the magnetic material and magnet components. Our technical support team are able to provide material selection, prototyping and other related services, for most of the cases free of charge to our customers.



Neodymium Iron Boron (NdFeB) magnets are a type of rare earth alloy with typical atomic structure of Nd2Fe14B which stands for 2 atoms of Neodymium, 14 atoms of Iron(Fe) and one atom of Boron. The sintered Neodymium Iron Boron magnet has higher magnetic properties compare to Samarium Cobalt magnets, however it is more easily oxidized and generally does not have the same temperature resistance. The highest energy products for Neodymium Iron Boron could reach 52 MGOe commercially or more…


Samarium Cobalt is another type of rare earth magnet materials that are highly resistant to oxidation, have a higher magnetic strength and temperature resistance than Alnico or Ceramic materials. Samarium cobalt magnets are divided into two main groups: SmCo5 and Sm2Co17with energy products range from the 1-5 series is 15-24 MGOe, the 2-17 series falling between 22-32 MGOe. These magnets offer the best temperature characteristics of all rare earth magnets and can withstand temperatures up to 315ºC…


As one of the members of magnets family, Alnico remains the workhorse of the permanent magnet industry and can be relied upon to deliver impressive flux density at an economical price. Excellent temperature stability, high residual induction, and relatively high energies characterize Alnico materials, composed primarily of alloy of Aluminum, Nickel, and Cobalt. They are manufactured through either a casting or sintering process. Cast magnets may be manufactured in complex shaped, such as horseshoes…


Hard ferrite ceramic (Hard Ferrite) magnets were developed in the 1960’s as a low cost alternative to metallic magnets. Compared with other permanent magnet materials they exhibit low energy and relatively brittle and hard, ferrite magnets have won wide acceptance due to their good resistance to demagnetization, excellent corrosion resistance and low price per pound. It is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors…


AMSC supplies magnetic assemblies with good quality and versatility.


We supply lost cost, high power strength magnetic assemblies. Various types of magnets are encased in plated or other surface coated steel cups, channels, plates or customer designed shapes. The magnetized magnet components can create 25 times or more pull force than an individual magnet.


Besides a large variety of common magnetic assembly models, we also provide the special magnetic device assemblies. These assemblies are made special for each individual customer per client’s submitted design. We will be able to help you select the style that best fit your applications.


  • Automotive sensors, motor and actuators
  • Oil and gas industry sensor and drive systems.
  • Chemical and food industries, permanent magnets drives cleans and safe motive power for couplings, pumps and blenders etc.
