Various types of industrial magnets are used depending on the product's purpose and usage environment. Hellomag supplies a variety of magnet products, including Ferrite Magnet and Ferrite Injection Magnet, and also supports custom design tailored to customer requirements.
In this article, we will focus on the characteristics of Ferrite Magnet and Ferrite Injection Magnet introduced by Hellomag.
What is Ferrite Magnet?
Ferrite Magnet is a ceramic permanent magnet that uses iron oxide (Fe₂O₃) as its main material.
This is a black magnet that is commonly seen when disassembling speakers. It does not use rare earth elements, so it is not subject to the Chinese government's rare earth sanctions.
is also cost-competitive based on its low unit price and does not require plating. What are the characteristics of
Ferrite Magnet? The main features of
Ferrite Magnet are as follows:
- Iron oxide (Fe₂O₃) based ceramic permanent magnet
- Rare earth free
- Low Price competitiveness based on unit price
- No plating required
- High heat resistance
- Operating temperature 250~300℃
- Maximum energy (BHmax) 3~4.5MGOe
Hellomag provides various magnetic grades from FB5B to FB13B, and custom grades tailored to customer requirements are also available.
What is Ferrite Magnet used for?
Hellomag introduces the main application fields of Ferrite Magnet as follows.
- Motor
- Speaker
- Sensor
Ferrite What is Injection Magnet?
Ferrite Injection Magnet is a composite magnet produced by injection molding by mixing ferrite powder and thermoplastic resin such as PA6, PA12, and PPS.
has high dimensional precision and features insert injection molding at the same time as the shaft. What are the characteristics of
Ferrite Injection Magnet? The main features of
Ferrite Injection Magnet are as follows:
- Mixed injection of ferrite powder with PA6, PA12, PPS
- High dimensional precision
- Insert simultaneously with shaft Injection possible
- Maximum energy product (BHmax) 1.0~2.5MGOe
- Operating temperature 100~150℃
Depending on the product, Nylon6, Nylon12 and PPS materials are applied, and the working temperature of PPS material products is 150~180℃.
Customized grades can also be manufactured to meet customer requirements.
