Small
Magnets
Description: We supply a wide range
of magnets that are used for a great variety of applications.
The three main materials are: alnico, ferrite (ceramic
strontium ferrite) and rare earth (neodymium iron boron).
We stock many items, and can usually guarantee next
day delivery if we receive orders by 11:30am. However
due to processing costs, we have a minimum order of
£40.00.
Please note that we only supply to industry.
Alnico Magnets
These are cast magnets manufactured from aluminium,
nickel and cobalt. They possess excellent corrosion
and heat resistant qualities up to 500°C.
Typical
applications include:
|
 |
"Pot" magnets for holding
and clamping |
|
Lifting |
|
Proximity switches |
|
High temperature fixtures |
Ferrite Magnets
Ceramic ferrite is manufactured from strontium ferrite,
usually die pressed and sintered. Due to good machining
properties, we can cut and magnetise them to virtually
any size or shape required. Due to their high coercivity
and low cost, they are used in a wide range of applications.
We also stock a wide range of blocks, rings and discs.
Stable up to a maximum temperature of 120°C.
Rare Earth Magnets Manufactured
from sintered neodymium iron boron. They possess the
most powerful magnetic properties in relation to volume
and can lift up to 1000 times their own weight. However
they do not possess strong heat resistant qualities
usually remaining stable up to 80°C although SH
grades of the compound are available which are stable
up to 200°C. For higher temperature applications,
rare earth samarium cobalt is recommended. Also due
to their corrosive nature, neodymium is usually supplied
coated.
We can also manufacture small block magnets to customer
requirements.
