Ferrofluid

Optimizing Ferrofluid for unique
applications for over 40 years.

Ferrotec has led the development of ferrofluid technology since 1968 and has worked closely with many companies as their new product teams incorporate ferrofluids in next-generation products. With a comprehensive fluid development and applications laboratories in both the US and Japan, and an experienced staff of scientists and engineers available to assist you, Ferrotec is well placed to help you solve your engineering challenges using ferrofluid.

Ferrofluids are a unique class of material. A ferrofluid is a stable colloidal suspension of sub-domain magnetic nano particles in a liquid carrier. The particles, which have an average size of about 100Å (10 nm), are coated with a stabilizing dispersing agent (surfactant) which prevents particle agglomeration even when a strong magnetic field gradient is applied to the ferrofluid.

Ferrotec ferrofluids are optimized to maximize performance in specific applications. Within each product series, you'll find that each product family offers a number of different ferrofluids with a variety of material properties and performance characteristics.

Ferrofluid for Specific Applications

While being a fluid, it is a functional material attracted to magnets and magnetized by external magnetic fields. In the 1960's NASA Space Program, it was developed to transport fuel in zero gravity. Currently it is used in speakers, actuators, sensors, recycling separation applications, and also in Vacuum seals.
