NdFeB Magnetic applications:
Loudspeakers, motor assemblies, windmill, Home appliance, acousics, communication equipment, toy, car, servomotor, step motor, DC motor and linear motor, mircrophones
Pros: Very strong hold when contacting another magnet or plain iron, very difficult to pull away (easy to slide however).
Pretty strong hold between two of these even with a couple of mm in between.
Cons: Would like thicker (and more powerful) versions. Sure u can stack these together but sometimes it's not the same thing.
Other Thoughts: Good for attaching thick stacks of paper to refrigerators etc or pinching together papers or textiles.
Bottomline: This is the one if you need strong cost-effective magnets

About NdFeB magnet:

Neodymium iron boron ( NdFeB) is a type of rare earth magnetic material.
NdFeB is the most advanced commercialized permanent magnet material available today.
This material has similar properties as the samarium cobalt except that it is more easily oxidized
and generally doesn't have the same temperature resistance.
However, NdFeB magnets have the highest energy products approaching 52MGOe and are
mechanically stronger than samarium cobalt magents. NdFeB material is more costly by weight than
ceramic or alnico but produces the highest amount of flux per unit of volume or mass amking it very economical for many applicantions. Their high energy products lend themselves to comnpact designs
that result in innovative applications and lower manufacturing costs.
Unprotected NdFeB magnets are subject to corronsion. Surface treatments has ben developed that
allow them to be used in most applications. These treatments include copper, silver,, gold, nickel,
zinc and tin plating and epoxy resin coating.
Beneficial characteristics of NdFeB magnets include their very high energy product, very high
coercive force, and moderate temperature stability. Drawbacks include lower mechanical strength,
and low corrosion resistance when not properly coated or plated.

Magnetic Grades and Temperature:



The Grade of a magent directly refers to the Maximum Energy Product of the material that composes the magnet. It in no way refers to the physical properties of the magnet. Grade is generally used to describe

how "strong" a permanent magnet material is. The energy products is specified in the unites Gauss Oersted.

One MGOe is 1,000,000 Gauss Obersted. A grade forty (N40) would have a Maximum Energy Product of 40 MGOe.The higher the grade the "stronger" the magnet.

Magnetic materials have a wide range of working temperatures. The following chart the various materials and their maximum working temperature. NdFeB material

Magnetic name tag is composed of two parts, first if the wearing part, the other is magnetic part. Actually all tags can be replaced by magnetic one by adjusting the wearing methods.



The magnets used in magnetic name tags are Neodymium disc magnets, because of their super strong magnetics, we do not need to worry about the lost of tags during daily works.
