Neodymium (NdFeB) Magnets Request for Quote


Neodymium (NdFeB) permanent magnet is composed of neodymium, iron, boron and a few transition metals. It has many advantages like high coercive force, high energy, high performance/ cost ratio and can be easily formed into various shapes and widely used in many fields such as aviation, electronics, instruments, meters, DC motors, Liner motors, MRI, medical and health products. It is the third generation of rare earth permanent magnet and at the same time the most powerful and advanced commercialized permanent magnet today.


Permanent magnet generator, NdFeB magnet is an alloy magnet made from Nd,Fe,B and other metal elements, which has the high remanence, high coercive force, high energy and high performance/cost ratio. The highest magnetic properties is from 33MGOe to 52MGOe,and we are able to control the magnetic properties within the range as you demanded, like SH,UH,EH such high stable properties could be produced as per your industrial application.
We focus on Sintered NdFeB magnet and develop it under experienced engineer and passionate & studious sales team.

1. Is it OK to print my logo on magnet product or package?
Yes. Please inform us formally before our production and confirm the design firstly based on our sample.


2. How does the magnet grade and magnet dimensions affects the Gauss Level of magnets?
Same magnet size, higher grade with higher gauss;
Same magnet grade, same surface area, the thicker, the higher gauss;
Same magnet grade, same thickness, larger surface area with lower gauss;


3. What does pulling force mean?
Pulling force is a measure of magnetic strength. It is the amount of force required to remove a magnet parallel to a solid
magnetic surface, such as a steel plate.


4. If I stick two neodymium magnets together, does their strength double?
No. It will a little smaller. For example, two magnets rated with a individual pulling force of 50 lbs will have a combined pulling force of 90 lbs when stick together.


5. Do neodymium magnets lose strength over time?
They don’t naturally lose any strength and will keep the strength permanently in the normal conditions, unless meet the high temperature over 80 degrees Celsius(℃), and then will lose the strength gradually.


6. What materials do magnets attract?
Ferromagnetic materials are strongly attracted by a magnetic force. The elements iron (Fe), nickel (Ni), and cobalt (Co) are the most commonly available elements. Steel is ferromagnetic because it is an alloy of iron and other metals.


7. How do you make our business long-term and good relationship?
a) We keep good quality and competitive price to ensure our customers benefit ;
b) We respect every customer as our friend and we sincerely do business and make friends with them
