Antigliss Rubberized Magnetic Pot

Magneti

The Antigliss Rubberized Magnetic Pot were created to overcome the physical problem of slipping of magnets working perpendicularly. The new exclusive material, rubber free of harmful substances, coupled with the magnets allows you to obtain almost the same force as when lifting (normally it would be reduced to a third). They use exclusively high-grade neodymium magnets.

magnetic pots with hole

Magneti

WKP Magnetic Pots are produced with Neodymium or Ferrite Magnets, by drawing process. A through hole, not threaded, but countersunk is always present. Coating is usually Nickel.

Magnets could be glued or resin bonded (both side or fully).

Special Magnetic Pot are usually made basing upon technical specifications given by the customer. External housing could be made of Iron, Brass, Aluminium, Stainless Steel.

It is possible to define the traction force (both at contact or at distance). In the below list we only report the most common magnetic pots.

Magneti

Patented in 1952, due to its exceptional value for money, it is by far the most widespread magnetic material.

Composed of a mixture of iron oxide and barium carbonate (or strontium), this magnet is produced by sintering.

The shapes produced are: parallelepiped, ring and disk.

Upon customer request it is possible to produce particular shapes based on drawings.

Standard tolerances are: ±2% on length and width and ±0.1 mm on thickness.

The obtainable magnetizations: axial, radial, diametral.

On request it is possible to create particular magnetizations, such as multipolar

The maximum operating temperature is approximately 280°C

Unlike Neodymium, ferrite magnets do not require a protective coating.

Neodymium-Iron-Boron NdFeB magnets (Rare Earth group) are the most technologically advanced product available on the market.

They are usually produced by sintering.

Thanks to these magnets, it has been possible to miniaturize a large number of commonly used components: think for example of hard drives for laptops or speakers.

Their energy product (BHMax) starts from a value (N35) of 33 MGOe: approximately 10 times that of Ferrite magnets and 7 times that of Alnico.

The standard magnetizations are: axial, radial, diametral.

The maximum operating temperature is approximately 230°C

On request it is possible to create particular magnetizations, such as multipolar

The standard shapes that are produced are: Parallelepiped, Ring and Disc. Upon customer request it is possible to produce particular shapes based on drawings.

Standard tolerances are: +/- 0.1

Given their natural tendency to oxidize when exposed to air, they are usually coated with surface treatments such as galvanizing and nickel plating.

Upon customer request, or for particular aesthetic and usage needs, it is possible to provide ad hoc coatings such as teflon, epoxy, gold, etc.

samarium cobalt

Magneti

For sale since 1980, Samarium Cobalt was the first magnetic material to revolutionize electric motor performance.

In fact, it provides a magnetic flux around 5 times greater than traditional materials like ferrite or alnico. It does not need any protective coating since, unlike Neodymium, it does not oxidize.

Samarium Cobalt is basically made up of a lot of pure cobalt, and this is why its price is particularly high. Moreover, Samarium Cobalt is very fragile, but it has the positive characteristic of being able to resist temperatures of up to a 250° C without undergoing any significant variation in power, and it is for this reason that, many years after the advent of Neodymium, this has continued to be used.

With the appearance of new Neodymium gradations that are resistant to high temperatures, Samarium Cobalt has been less in demand by clients worldwide, who have preferred to use Neodymium since the cost is significantly lower.

During the pricing crisis of 2011, many users went back to buy Samarium Cobalt because Neodymium prices had increased so much as to render Samarium Cobalt even more attractive. This situation only lasted for a few months.

The prediction is that in the future, barring any absurd spikes in Rare Earth prices, the production of Samarium Cobalt will gradually and constantly decrease.
