Ferrofluid

A Mysterious Liquid with Magnetic Attraction

Ferrofluid 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, one of our company’s core products.
