Round NdFeB Magnet (ND-Fe-B) are composed of neodymium, iron, boron and a few transition metals. These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs.

Size of Rod NdFeB Magnet:
Disc: Max: Diameter 202mm*45mm thickness---Min: Diameter 1.5mm*0.5mm thickness
Ring: Max: Od202mm*ID182mm*thickness 45mm---Min: OD 3mm*ID1mm*3mm thickness
Block: Max: L200mm*W200mm*T45mm---Min: L0.5mm*W0.5mm*T0.5mm.
Sizes can according to customers' requirements.

Rod NdFeB Magnet:
Shape: Disc
Magnetic Face: 5mm dia
Thickness: 10mm
Grade: N42
Plating: Ni-Cu-Ni ( Nickel )
Material: NdFeB

These magnets will have approximately 4600 Gauss on each face. Each magnet can support a steel weight of up to 0.9kg vertically from the magnetic face when in flush contact with a mild steel surface of equal thickness to the magnet. Each magnet can also support up to 0.18kgs in a shear position before beginning to slide down a steel surface under the same conditions. These magnets can be fixed in place using Araldite/Loctite and have a maximum operating temperature of 80 degrees C.
