Sintered NdFeB Small Block Magnet

NdFeB Magnets Overview 

Neodymium Iron Boron (NdFeB) magnets , a sort of Rare Earth magnet material,has the high remanence, high coercive force, high Maximum energy and is easily formed into various sizes,shapes.So they have been widely used in commercially available fields since the mid -1980's.

It can be manufactured by sintering, compression bonding, injection molding, and extrusion. The sintered form holds the highest energy product of up to 51MGOe, while the bonded form holds a lower energy product of up to 10MGOe.Furthermore,The majority of NdFeB magnets are anisotropic and can only be magnetized in the orientation direction.

NdFeB Magnets are prone to corrosion in humid environments, It usually need surface treatment according to customer's requirements to protect magnet. Surface Treatment Methods are Zinc,Nickel,Chrome,Silver or Gold Plating, Phosphor,Spray Epoxy Resin etc.

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. 

HSMAG Magnets has been supplying high quality Neodymium Magnets to customers for about 20 years.
