Terms and Definitions

Br (KG) - "Residual Flux Density Measured in Kilo Gauss"
This is a measurement of the material's ability to retain a magnetic field after being magnetized.
For Example: Iron can be temporarily magnetized but will lose the majority of its magnetic strength when the external field is taken away. This is because Iron has a low Residual Flux Density.

HcB (KOe) - "External Force Required to Demagnetize Measured in Kilo Oersteds" 
This is a measurement of the material's ability to resist external and internal magnetic forces without being changed.
For Example: Flexible/rubberized magnets have a lower HcB and therefore can be easily demagnetized / remagnetized by a stronger neodymium magnet.
Neodymium magnets will lose about 1% of their magnetic strength every 10 years due to self demagnetization.

BHMax (MGOe) - "Maximum Energy Product Measured in Mega Gauss Oersteds"
This is a direct measurement of a materials maximum magnetic strength after the magnet is fully saturated "charged" by an external magnetic field. BHMax is the best indication of a given materials attractive power.

Tmax (Maximum Operating Temperature) - "Measured in Celsius / Fahrenheit"
Heating a magnet above its maximum operating temperature will cause it to permanently lose its magnetism until it is remagnetized by a strong external field. Heating the material close to the maximum operating temperature (usually within the 20% range) will cause the magnet to temporarly lose its magnetic strength until it cools.
 

Sintered NdFeB magnets are strong permanent magnets made of an alloy of neodyumium, Iron, and Boron. NdFeB Magnets are the strongest available magnets, but have a low maximum temperature resistance. NefeB Magnets Will oxidize rapidly, so an anti-corrosive coating is needed to protect the substrate. See Plating and Coating options for more information. View Selection

SmCo magnets are made of a strong permanent magnet alloy of samarium and cobalt. Compared to NdFeB magnets, SmCo magnets are weaker, but are more suiteable for working in higher temperatures. SmCo magnets are very anti-corrosive and generally do not require electroplated surface treatment.

Bonded NdFeB is a cast/molded type of NdFeB which can be further machined and pressed into different shapes like rings, arcs, and many more complex geometries. It also has a higher corrosion resistance compared with sintered NdFeB. Bonded magnets offer less magnetic strength than sintered magnets s but can be formed into intricately shaped parts.

AlNiCo magnets are very stable and have good corrosion resistance and a typical hardness of 50 Rockwell C. AlNiCo represents the most versatile magnet material available. The range of properties can be accurately designed for specific applications by changes to element analysis and heat treatment.

Ceramic, also known as Ferrite magnets are made of a composite of iron oxide and barium/strontium carbonate by ceramic processing technology. Ferrites are, like most other ceramics, hard and brittle. In terms of the magnetic properties, ferrites are often classified as "soft" and "hard" which refers to their low or high coercivity of their magnetism, respectively.

Flexible Rubber magnets are made by mixing Ferrite or Neodymium magnet powders and synthetic or natural rubber binders. They are made by rolling (calendaring) or extrusion methods. Flexible magnets are applied because of their advantages of versatility, low cost, and ease of use. These magnets are usually manufactured in strip or sheet form that is widely used in micro-motors, gaskets, novelties, signs, and displays.
