Toshiba pioneered the development of Cobalt (Co)-based amorphous (non-crystalline) magnetic alloys for electronic applications. Toshiba offers amorphous magnetic cores for noise suppression, mag-amps, snubbers and pulse transformers. Key applications for these amorphous cores include switching power supplies, noise sensitive equipment, medical instruments and telecommunications.
Improvements in magnetic properties have resulted from Toshiba's commitment to research and development. Toshiba continues its R&D programs to further improve the properties of the amorphous alloys and the magnetic components made from them.

Molybdenum Permalloy, HI-FLUX® and SUPER-MSS® (sendust) powder cores are wound with magnet wire to make transformers or inductors. Maximum allowable energy dissipation for a given value of energy storage (inductance and current) or transformation (voltage and current), guide the selection of core material and size. Energy dissipation is usually specified in terms of maximum temperature rise, minimum efficiency or minimum Q value. Consider the following when choosing a core material.
- Molybdenum Permalloy Powder (MPP) cores provide the maximum Q and lowest core loss. MPP is the most stable core with respect to temperature and AC flux. It has the widest range of permeabilities and is considered the premium material for direct current output inductors of switched mode power supplies.
- HI-FLUX cores are a 50% nickel, 50% iron distributed air gap powder core. HF has up to 15,000 Gauss saturation flux density and core losses significantly lower than iron powder cores. These cores are ideal for switching regulator inductors, in-line noise filters, pulse and fly-back transformers applications. When used in applications with high DC current, HF cores can provide a reduction in inductor size as well as total cost.
- SUPER-MSS is an improved Sendust material, originally develped by Arnold Engineering. It is designed to replace iron powder by offering much lower losses, with energy storage capability higher than MPP. SUPER-MSS cores are an excellent choice for energy storage and filter inductor applications in switch mode power supplies. The DC bias characteristics of SUPER-MSS are also excellent compared to iron powder of similar permeabilities and size.

Alnico magnets, composed of primarily aluminum, nickel, and cobalt, were developed in the 1940's. This class of magnet remains a preferred material because of it's excellent temperature stability, high magnetic flux density, and resistance to corrosion. Alnico magnets are manufactured through a casting or sinter process. The casting process allows for the magnet to be manufactured into intricate and complex shapes, which are not possible with other magnetic materials.
Ningbo Tongchuang Strong Magnet Material Co.,Ltd is an original factory specializing in Neodymium magnets, and also manufacturing and marketing
other permanent magnets, such as Sm-Co, Al-Ni-Co, hard ferrite and rubber magnets.

MU METAL® offers important electromagnetic field shielding characteristics, including very high magnetic permeability - its ability to absorb magnetic energy. The unique properties of this family of alloys results in the highest possible attenuation, making these shielding alloys the materials of choice for reducing low-frequency electromagnetic interference (EMI).
MU METAL® is a trademarked brand of Magnetic Shield Corporation. MU METAL® meets MILSPEC 14411C, composition 1. When the specification or the application calls for a magnetically soft or high permeability material, MU METAL® can frequently be successfully applied.
MU METAL® magnetic shielding prevents magnetic fields from reaching areas where they would cause magnetic interference. Magnetic shielding is used around either the source of interference, to prevent electromagnetic radiation from leaving a device; or more typically, around a sensitive device, to prevent the electro magnetic interference (EMI) from disrupting normal operations.
