Ferrofluid - Shaping The Automobile Industry Of The Future

What does it take to change our world? One person? A group of ten? A mob of thousand? Well, how about trillions of atoms? Science has advanced to such an extent that trillions of atoms and molecules just nanometers in width can make a huge difference to our planet as we know it. Ferrorfluid is one new development set to revolutionize industries where speakers, shock absorbent materials, seals, and other such products are used. Auto industry is set to gain the most.

Ferrum, in Latin, means iron. Not surprisingly, this fluid consists of iron that is suspended in any liquid. The liquid is either water or any other organic based substance. The resulting combination is called hematite or magnetite. The dispersal of the particles is done with help of surfactant process. The final consequence is that base becomes colloidal. Further, this surfactant process stops this coating from acquiring a magnetic field. Further, the Van Der Waals causes various ferrous particles to get clumped together. This process results in this fluid that consists of superparamagnetic qualities.





What makes Ferrofluids so useful? This liquid acts as a very good seal. All it takes is bit of magnetism for this seal to become watertight. The liquid's quality is that it becomes airtight. It becomes virtually immune from friction no matter how much wear and tear takes place. The seal remains fluid, dynamic and flexible. Just imagine how this product will work in your car's driveshaft? Many car makers use ferrofluids and prepare the seals to locks driveshaft and drive train in the car together. This option is used when making all or four wheel drive cars. Just press any button and the ferrofluid will kick making a great seal. This will not take more than a few seconds. The electricity based magnet will be fitted inside the differential and the effect will be instantaneous.

Another next benefit of ferrofluid is that it is great in absorbing shocks. If one uses lubricants based on oil and ferrofluid, it will be very easy to dampen shocks effectively at all times. Control of traction and absorbing shock as you wish - this will become possible with presence of the magnet powered by electricity. The driver can make infinite adjustments in a few seconds.


Ferrofluid is making a huge impact on the automobile industry. The substance has been helping automobiles reach optimum performance. It also helps sustain peak performance for longer durations. The refinement in technology is taking place constantly. What may be a dream today can become reality with help of the substance. This development falls in 'must watch' segment. Sooner or later, people are going to find ways to use this fluid in various other industries as well.
