5) Coating: Gold,Silver,Ni/Nickel,NiCuNi/Nickel-Cu-Nickel,Black Nickel,Zn/Zinc,Epoxy,Cu platedAnd etc;
6) Application: Sensors, Motors, Rotors, wind turbines,wind generators, loudspeakers, magnetic hooks, magnetic holder, filters automobiles and so on;
7)Certificate: ISO/TS 16949 ;
Distinctive feature: These pot magnets can be fastened with a countersunk screw. We also carry pot magnets with cylindrical borehole.
Principle: The strong neodymium magnets are embedded in a steel pot. The steel pot increases the adhesive force of the magnet on direct contact with a thick iron surface. If there is no direct contact with the counterpart, or if the steel plate is thin, painted or rough, you can strain it much less.
Shear force: The indicated adhesive force was measured perpendicular to the surface to which the magnet should stick. It takes a lot less strength to move the magnet sideways. Therefore, you can strain a pot magnet much less if you use it on a wall as opposed to using it on the ceiling.

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.
