Ferrite magnet
Compo Tech Co.
RD Europe Group ferrite magnets are subdivided into two groups:
Dry anisotropic ferrites, used for electric motors dedicated to automotive and home appliances sectors
And wet anisotropic ferrites used for power tools and automation motors.
Magnets are usually assembled on permanent magnets electric motors, with brushes or brushless, for sectors like automotive, home appliances, automation, power tools, pumps, loud speakers and robotics.
The main ferrite and plastoferrite magnets applications are:
56% automotive
24% home appliances
20% other motors
The line of anisotropic wet magnets has the most wide applications purposes because of widen magnetic features choice. There are five main magnet classifications: 3,4,5,6 and 7. The last one offers higher magnetic proprieties with a range of residual induction (Br) from 4100 to 4600 Gs and intrinsic coercitivity (Hcj) from 5099 to 3393 Oe which satisfy every performance request.
Please see attached tables for more technical details.
The main feature of ferrite magnets is their hardness, in fact they are called "hard ferrite". This is possible thanks to a very important production process called sinterization, a sort of thermal treatment which welds powders when temperature almost reaches the fusion point. This gives hardness to ferrites but also is economic for series production. They are so called sinterized magnets.
