Hangseng Magnetech Inc. (SUPERMAG, neoi) is your best source for the highest quality magnets, neodymium magnets, magnetic devices and expert application assistance for OEM, point-of-purchase, industrial and retail markets.
Note that NdFeB magnets are covered by various patents (held by Neomax) and only licensed materials are allowed into the USA. There are a number of sources that do sell unlicensed products to those willing to purchase them. HSMAG does not sell unlicensed materials.
Very high strength
Relatively low cost (by weight about 20 times Ferrite magnets, by “Dollars per BHmax” about 1.5 times Ferrite magnets).
Relatively easy to machine, compared to Alnico and SmCo magnets.
Properties deteriorate rapidly at temperatures in excess of about 150°C (depending on grade and permeance coefficient magnet is operating at).
Most grades of NdFeB magnets need to be protected against oxidation – by coating or plating the magnets.
N28AH Neodymium Magnets Magnetic properties
Some important properties used to compare permanent magnets are:
which measures the strength of the magnetic field
the material’s resistance to becoming demagnetized
Energy product (BHmax)
the density of magnetic energy
Curie temperature (TC)
the temperature at which the material loses its magnetism
Neodymium magnets have higher remanence, much higher coercivity and energy product, but often lower Curie temperature than other types. Special neodymium magnet alloys that include terbium and dysprosium have been developed that have higher Curie temperature, allowing them to tolerate higher temperatures.[fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”] The table below compares the magnetic performance of neodymium magnets with other types of permanent magnets.[/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]
