Welcome to our web site! Since 1988 Sigma Hi-Chemical has been developing the technology of magnetic fluid and ultra-fine magnetic particles.You can get technical information from these pages.

Magnetic Fluid

The mysterious fluid is attracted by magnets. It is widely used for rotating shaft seals, dampers or sensors.
Sigma Hi-Chemical is one of the rare companies in the world that willingly provide magnetic fluid alone.

Spike Ball (colorful magnetic fluid for enjoyment)

You will have interesting time when you get this Spike Ball. You can control magnetic fluid in the bottle with an attached magnet and you realize movement. The spike will do back and forth depend on your magnet. Please try to play with Spike ball!

Colloid for Ferromagnetic Material's Domain

Ferromagnetic material such as steel is a collection of small, randomly arranged magnets, or magnetic domains.

Using the colloids, clear geometrical patterns of domains can be seen.

They are applicable to hard or soft magnetic materials, also to magnetic solids or films.

Developer for Magnetic Records

Magnetically recorded signals on a medium are aligned systematically on a track. They are invisible, as a matter of course, but when using our Colloids they are visualized to details. And you may see beautiful colors caused by interference of light on the surface.

Magnetic Viewer

Today, it may be difficult to think of daily life without magnetic cards or magnetic tickets. The Viewer offers outstanding performance to inspection of these magnetic media and machines.

Just putting it on a card, the magnetic codes appear on the screen.
