Alnico Magnets

Aluminum, Nickel, Cobalt (referred to as Alnico) is manufactured by traditional foundry casting or sintering techniques developed in the 1930’s. This kind of material offers the best temperature coefficient (0.02% per degree centigrade) of all permanent magnets making it an ideal choice when a constant field over a wide temperature […]

Bonded Ferrite Magnets

Bonded ferrite magnets are a composite material of ferrite magnetic powder and compound rubber or plastic. The products are available in both anisotropic & isotropic grades. Detailed product specifications are available upon request.

Bonded NdFeB Magnets

Bonded Neodymium magnets are produced using compression molding techniques that can be quickly machined into complex shapes. The material is made in an isotropic process and the performance can reach up to 12 MGOe. It has a maximum operating temperature of 120°C but a rather poor temperature coefficient. The Curie […]

Sintered Ferrite / Ceramic Magnets

Developed in the late 1950’s, sintered ferrite (ceramic magnets) are manufactured from a composite powder containing 80% iron oxide and 20% barium or strontium oxide. This powder is die pressed into a component that is sintered in a kiln at approximately 1200°C. Sintered ferrite has a wide range of applications […]

Sintered NdFeB Magnets

Sintered NdFeB magnets are manufactured under powder metallurgy technology. Compared with other magnetic material, it has the highest energy. Based upon the current research and development, the BHmax has reached over 50 MGOe and it is still going higher. It is widely used in various applications. However, it still has […]

Sintered SmCo Magnets

Sintered Samarium Cobalt rare‐earth (SmCo) magnets are manufactured under powder metallurgy techniques. The composition of this alloy is approximately 35% Samarium, 60% cobalt with the balance being Fe and Cu. By adjusting the percentages of this composition and changing the sintering & heat treatment cycles, two grades of 1:5 and […]

Soft Ferrite

The soft ferrite contains Ni, Zn, and/or Mn compounds are used in transformer or electromagnetic cores. They have a low coercivity so they are called soft ferrites. The low coercivity means the material’s magnetization can easily reverse direction without dissipating much energy, while the material’s high resistivity prevents eddy currents […]
