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.

Shapes available – blocks, bars, discs, rings, arc segments, etc.
Grades available – from about 3330 to 5311. (First 2 digits represent BHmax, and second two digits represent Intrinsic Coercivity, Hci.)
Sizes – off tool the largest die pressed blocks are about 4″ cube, while isostatically pressed blocks can be much longer in the orientation direction (up to 9 feet).
Machining – Neodymium magnets should be machined by grinding using diamond wheels, However, of the hard magnet materials, Neo magnets are the least difficult to machine. We have successfully machined very small magnets – down to 0.012″ diameter with a center hole of 0.003″ diameter, 0.040″ long.

[A] The term Rare Earth Magnets is used to refer to a group of magnetic materials whose alloys consist of one or more of the Rare Earth elements on the periodic table. These materials are characterized by exceptionally strong magnetic properties.
[Q] What are alnico magnets?
[A] Alnico magnets are aluminum-nickel-cobalt magnets.
[Q] What are ceramic magnets?
[A] Ceramic magnets are made from strontium and iron oxide powders. They are generally harder, more brittle and lighter than metal alloy magnets. Ceramic magnets have a high electrical resistance.
[Q] What are magnetic assemblies?
[A] Magnetic assemblies are up to 32 times stronger than regular magnets and are typically made with ceramic magnets. We can make magnetic assemblies in custom sizes, designs, and coatings.
[Q] What are permanent magnets made of?
[A] Today’s permanent magnets are made of alloys. Alloy materials include
Aluminum-Nickel-Cobalt (Alnico)
Neodymium-Iron-Boron (Neo magnets or “super magnets”, a member of the rare earth category)
Samarium-Cobalt (a member of the rare earth category)
Strontium-Iron (Ferrite or Ceramic)[/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]
