Self-Adhensive Magnets

  • Sintered NdFeB with Tape: N35, N38, N42

Our self-adhesive magnets combine a strong magnetic force Neodymium and the convenience of self-adhesive with a peel away backing tape.


NdFeB is the strongest type of permanent magnet commercially available:

  • Higher remanence (the strength of the magnetic field);
  • Higher coercivity (resistance to being demagnetized);
  • Higher energy product (density of magnetic energy).

Self-Adhesive Magnets

General Introduction

Our self-adhesive magnets combine a strong magnetic force Neodymium and the convenience of self-adhesive with a peel away backing tape.

Features

Besides the capability of self-adhesive, the magnets features is same as Neodymium: Higher remanence (the strength of the magnetic field), coercivity (resistance to being demagnetized), and energy product (density of magnetic energy) than other type magnets, however often lower curie temperature.

Typical Grades

Typical used grade of Neodymium is N35, N38, N42
With 3M tapes

Property

Some important properties used in Neodymium magnets are:

  • Remanence (Br), measure the strength of the magnetic field;
  • Coercivity (Hcb / Hcj), the material's resistance to becoming demagnetized;
  • Energy product (BHmax), the density of magnetic energy, which relates to the magnetic flux output per unit volume. Higher values indicate stronger magnets;
  • Curie temperature (Tc), the temperature at which the material loses its magnetism.

Shape

Typical self-adhesive neodymium magnets are shaped into:

  • Disk, Bar.

Custom design is available to us for client`s specific needs

Coating

NdFeB tends to be vulnerable to corrosion, which could cause serious deterioration, including crumbling of a magnet into a powder of small magnetic particles, or spalling of a surface layer. Coating prevents these magnets from oxidation.
Widely used coatings are NiCuNi, Ni, Zn, Epoxy, as well as some special coatings, for example, Copper, Gold, Silver, and etc.

Application

Some examples of the self-adhesive neodymium magnets are:

  • Fridge magnets;
  • Book and folder closures;
  • Craft making;
  • Packaging.
