Ferrite or Neodymium – Which One to Choose?

Many of them get confused when it comes to choosing between Ferrite and Neodymium magnets. Well, this depends on how you desire to utilize the magnets.

Ferrite magnets are recommended for following circumstances

  • External use
  • High temperature
  • Tight budget
  • No need for aesthetics

Neodymium magnets are recommended for following circumstances

  • Miniaturization [limited space]
  • Extremely high adhesive force needed
  • Less weight needed
  • Decoration or nice coating

Ferrite vs. neodymium

Make sure to locate the best ferrite and neodymium magnet manufacturer for your project but first decide the suitable magnet type.

Adhesive force

Neodymium magnets are stronger than ferrite magnets of same volume. So, if your place is small then former would be the preferred material.

Price

Ferrite magnets are two to three times cheaper than the neodymium magnets. If size and weight does not matter than ferrite magnet is large and heavier than neodymium magnets with same adhesive force. Ferrite magnet prices fluctuate less because their production doesn’t need rare earth metals.

Outdoor usage

Ferrite magnets are resistant to chemicals and rust but neodymium magnets are unsuitable for external use.

Brittleness

Neodymium magnets are extremely brittle, so crack easily but ferrite magnets break only when strain is repeatedly applied on them.

Adhesive force loss

When ferrite and neodymium magnets lose magnetism on their own. Only external factors like strong outer magnetic field or heat can demagnetize.

Transference

Small ferrite magnets display weak magnetic field, which can be isolated very easily, while neodymium magnets need extra effort to transport them. Both types need to be transferred to distance minimal 22 mm or else neodymium can demagnetize.

Coercive field

Strong neodymium has force to demagnetize or reverse ferrite magnets polarity. Minimal distance between different kinds of magnets need to be followed in respect to transport and storage.

Aesthetics

Ferrite magnets are uncoated and have unappealing dark gray color with uneven surface and dents on edges so unsuitable for using as name tags in clothing. Alternatively, neodymium has attractive silver color obtained from nickel coating, so don’t stain and are appropriate for gifts and decorations.
