Micro Magnets
For this products we confirm RoHS-conformity
Our supplier specialized in the production of micromagnets for the watch industry, Quick-Ohm is also
striving to conquer other industries. Numerous instruments in dashboards of automobiles
and aircrafts are equipped with stepper motors applications containing Quick-Ohm
micromagnets.
Micromagnets are also used in dental prothesis and implants.
Magnets made of Rare-Earth Cobalt
Micro magnets (Rare-Earth Permanent Magnets).

As a supplier of the famous Swiss watch industry, Quick-Ohm's skills for these products are based on a longtime experience. We provide solutions for a variety of technical problems, especially where high energies within smallest dimensions are required.
Besides watch magnets, Quick-Ohm also provides permanent micromagnets for industrial applications. (Special magnet materials with different energy products and material properties are available on request).
Demagnetization curves of the most common materials used by Quick-Ohm:
Magnets made of Samarium Cobalt 5
Magnets made of Samarium Cobalt 5 (SmCo5)

This alloy is best suited where little space is available and maximum energy is required. SmCo5 is little sensitive to corrosion and may be used to temperatures up to 250 degrees Celsius.
On request, Quick-Ohm provides coating of the magnets.
You have a choice of:
- tin, nickel, gold
- parylene and other plastic based coatings.
For absolute tightness and biocompatibility, magnets may be first covered by a layer of tin followed by gold and a final layer of parylene. This provides best possible protection to corrosion.

Magnets made of Samarium Cobalt 5-K

(SmCo5-K plastic bonded)
This alloy was developed for applications where difficult shapes are required. This material has good machineability for small and complex shapes showing less edge chipping compared to the pure SmCo. To top its advantages, the price/performance ratio is highly competitive.
Due to the plastic bonding, its energy product is much reduced compared to pure SmCo. Furthermore, this alloy’s maximum working temperature shall not exceed 80 degrees Celsius.

Magnets made of Samarium 2 Cobalt 17
Magnets made of Samarium 2 Cobalt 17 (Sm2Co17)

This alloy provides the highest energy density and good resistance to high temperature (300 degrees Celsius). It is the first choice for small dimensional applications requiring high energy in a high temperature environment.
However, its material structure is not suitable for complex geometrical shapes.
Magnets made of Neodymium-Iron-Boron
Magnets made of Neodym-Iron-Boron (Nd-Fe-B)

This material provides the highest energy product and remanence currently available. As indicated by its name, this material contains iron and bor, two elements that are readily available. Neodym-Iron-Boron is less expensive than Samarium Cobalt material.
Certain alloys may be used in temperatures as high as 180 degrees Celsius. Due to the iron content this material is sensitive to corrosion thus requiring a coating or surface treatment.
