Why Choose HSMAG for Rare Earth Magnets?

HSMAG' knowledgeable engineering department is always available to assist in determining the best grade and size of rare earth strong magnet for your application. We also offer coating and plating choices for magnets we custom-machine.

HSMAG has strong magnets in block, ring and disc form in a variety of sizes and grades, and we are fully equipped to produce the size and tolerance that you require.

strong magnet, strong magnets, rare earth magnets 

The term "strong magnet" is used most frequently to describe rare earth magnets, which are the strongest permanent magnets available.

Electromagnets and other types of magnets are also available in varying strengths. But when only the most powerful and reliable solutions are needed for industrial applications, rare earth magnets should be the first choice when a strong magnet is required.

Developed in the 1970s and 80s, these strong magnets are substantially stronger than ceramic or Alnico magnets.

Types of Rare Earth Magnet

HSMAG offers two types of strong rare earth magnets: Neodymium and samarium cobalt. Of these, Neodymium is the most commonly used. While usually small in size, these magnets have a high energy, and an extremely high resistance to demagnetization.

These strong magnets are used for the following applications:

•DC and servo motors

•Linear actuators

•Magnetic separators

•Speakers

•Microphone assemblies

•Sensors

•High performance motors

•Holding devices

•Closure devices

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.
