SELECTION SUPPORT · QUOTATION

Tell us your medium and your goal
We will name the grade

The most useful thing you can tell us is what you are working in and what you need the fluid to do. With that, we can recommend a specific grade from the 26, quote it, and send the MSDS — usually within 48 hours. If ferrofluid is the wrong material for your application, we will tell you that instead.

GETTING A GOOD ANSWER

How to get a useful recommendation on the first reply

Say what the fluid touches
Water-based, oil-based or dry powder is decided by the medium, not by the magnetic strength you want. pH and ionic strength decide whether you need a P-suffix grade.
Say what field you have
A permanent magnet in a lab and an electromagnet in a fixture give very different results. If you have a target force or gap, that is even better than a grade reference.
Say what "working" means
Visible domain walls under a microscope, a bead that separates cleanly, a seal that holds for a thousand hours — each points to a different grade.
Ask us to disagree
If ferrofluid is the wrong material — for instance you actually need magnetorheological fluid to transmit torque — we will say so. It saves you more time than a fast quote does.
