Raw Material of micro magnet:
Samarium Cobalt (SmCo)
Ferrite (Ceramic)
Aluminum Nickel Cobalt (Alnico)
Neodymium Iron Boron (Neo)
* ultra-small neodymium magnets are limited to bonded magnetic
Tolerance of micro magnet
The diameter can be supplied as small as 0.001 mm, tolerances without coating or plating is ±0.005 mm.
Coating of Micro Magnet:
NiCuNi
Epoxy
Parylene
As well as manufacturing a variety of micro magnet solutions, OZENZ can provide an array of coating or plating options. such as Nickel and Epoxy. For ultra-small magnetic, Parylene C which is oftentimes is the best solution. Because parylene can protest the magnet well and the thickness can be control easily. And most important an inert biocompatible protective coating.
Typical Miniature Magnet Applications:
Sensor (for use with Hall Effect Chips)
Motors
Electroacoustic
Microwave Tubes
Couplers
Coreless motor
Motors such as high-performance compact actuators
Microphones
Gyroscopes
Loudspeakers
Connectors
