Neodymium Disc Magnet

Model NO.: DISK

Product Description
Application Description

Neodymium disc magnets are kind of the thin round NdFeb magnet, which also called Neodymium circle magnet.
They feature as strong &stable holding force, which are easy to be found in fields of display units, bags and
suitcases, folders, molds and other industry applications. A coating protection is necessary due to the neodymium
disc magnets are poor in corrosion resistance

Industrial applications
– Motors
– Lifting &Holding
–Art, Craft, Model
– Audio components
–Science & Research
–Electronis

Material: Neodymium ,Ndfeb
Magnetization: Axially magnetized or diametrically magnetized is available
Coating: These round Magnet can be coating Ni, Zn, Au, Ag, Epoxy, Teflon, NiCuNi, etc;
Dimension: 1mm < = D <=250mm , 0.5mm < = H <=80mm if axially magnetized or
1mm < = D <=60mm , 0.5mm < = H <=80mm if diametrically magnetized;

Uncoated disc magnet dimension tolerance for reference.
