Ferrofluid is a functional material that was developed by the Space Program in the 1960s, although it is a liquid, it is magnetized by an external magnetic field and has the property of being attracted to a magnet.
It is extremely effective in radiating heat from drive parts such as speaker coils, and has been used for almost all high-frequency reproduction speakers (tweeters) for many years, including on-board applications.
In recent years, applications such as vibration control of tactile devices for touch screen panels and recycling of automobile scraps (precision weight difference sorting) have expanded to a wide range of applications.

We have developed various composite products based on the magnetic fluid nanotechnology, which exhibit an exceedingly high magnetic response in high frequescies .
The name shows the characteristic of magnetic hysteresis is almost zero.It can also be induced by a magnetic field, used todetect and repair cracks, and reduce the leakage of magnetic flux from gaps.
Based on various resin materials, it is also possible to provide solid products, rubbers, gels, sponge materials and other molded products, and liquid products such as adhesives.

Temperature Sensitive Ferrofluid

for Pump-less Heat Transfer System

We are now selling “thermosensitive magnetic fluid” that changes magnetic characteristics by temperature. Closed-loop Heat transporting systems are actively developed in many fields with this special characteristic. The pump-less heat transporting system without electricity is drawing attention as an essential future vehicle technology.
