Product Description

Ferrite Magnets - General Information

Ferrite, also known as Ceramic, magnets were formulated in the 1950s by Phillips in Holland. The major raw material used to manufacture Ferrite magnets is very inexpensive - iron oxide, more commonly known as "rust"! Due to their low cost, they are the most commonly used permanent magnets even today.

Ferrite Magnets Benefits

Inexpensive yet strong; a good balance between strength and affordability

Does not demagnetize easily

Can be magnetized with multiple poles if necessary.

Does not rust


1,great variety 

2,strong magnet force 

3,perfect price 

4,stable performance


High Quality China Hard Ferrite Magnet 

1. high anti-demagnetization 

2. high anti-corrosion 

3. low cost

Hard ferrite (ceramic) magnets were developed in the 1960's as a low cost alternative to metallic magnets. Even though they exhibit low energy (compared with other permanent magnet materials) and are relatively brittle and hard, ferrite magnets have won wide acceptance due to their good resistance to demagnetization, excellent corrosion resistance and low price per pound. In fact, measured by weight, ferrite represents more than 75 percent of the world magnet consumption. It is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors.

PCT:130c ,humidity 100%,vapor pressure 2.7 bar.20 days,average low weight loss less than 2 mg/cm2

Common Applications :

Sensors   Linear actuators   Microphone assemblies    Magnetic separators   DC and servo motors   Speakers   Printers   Magnetic hooksComputer rigid disc drives   Beam controls   Intelligent toys   MRI/NMR

We are specialized in producing NdFeB Magnet over many years,We guarantee the best price based on the same quality and service. Our finance conditiearon and industrial reputation are excellent.

Testing Center

We are ISO/TS16949:2002 certified and well implement all procedures strictly under control. Problem preventive actions and quality assurance are preoperly combined with special inspection for all procedures from raw material purchasing ,outside cooperating part manufacturing,inside manufacturing to shipping . We also install a complete set of physical and chemical test equipment to make sure that all our products are manufactured and shipped under strictly quality control .

Salt Spray Test :

Mainly test the surface treatment against the corrosion.  Usually the tested samples will be  continuous sprayed 24 hours in the 35℃ temperature to see if there is any rust appearance on the surface. 

Projection Instrument:

Mainly test the magnets with irregular shapes such as arc segments and any other irregular-shaped parts to see if their dimensions meet the customers' requirements or not.  

PCT Instrument:

Mainly test the magnets to prevent against corrosion on the high temperature and high atmospheric pressure . Usually the test condition is 120℃ temperature and 2 atmospheric pressure .

Heat& Humidity Instrument:

Mainly test the magnet to against corrosion on certain temperature and humidity . Usually the test condition is 80℃ temperature and 90%+/-3% humidity

Hysteresgraph:

Mainly test the magnetic characteristics of the magnet, including Residual (Br ), Coercive(Hcb) . Intrinsic  Coercive(Hcj), Max. Energy product(BH max) and any other related magnetic parameters.
