N52 Super Strong Disc Magnets , Neodymium Disc Magnets For
Packaging
What is the grade in neodymium magnets?
Neodymium magnets classified as N35, N38, N40, N42, N45, N48, N50,
N52(andN35M-N50M; N35H-N48H, N35SH-N45SH),
Grade is usually used for describe how “strong” a permanent
magnetic materials is, Neodymium is abbreviated to The letter “N”,
and the number after it represents the grade of the magnet.
Production advantages:
When you know what you need, just please send your magnet
specification and drawings for checking,
In case of new project, we can help you provide the design drawing
for you after discussion
Our Services:
1. Technical consult:
Our engineers will evaluate every project and give the best
solution to you in short time, we have special team work for after
sales services.
2. Design and Tool supports:
More than 12 years professional factory production line for OEM and
ODM magnet solutions, thousands of molding tools available for your
customized magnet design, you think it, we make it for you.
3. Measuring of magnetic properties
Quality is our culture, all our products is coming with good
quality finished and Demagnetization curve.
4. Testing of customer’s material and magnet performance
We know most of customers have not much professional equipment for
their magnet testing,
But do not worry, we can free of charge help you test if it is
true.
When you buy magnets with a very lower price, or you think
something is not good when use the magnets,
you can ask us for help, we will do the professional testing and
let you know what you get.
5. Fast and safety shipping
We have worked with some experienced Express courier and Sea
shipper more than 10 years, we can guarantee every process of your
magnet order from materials, design, production, testing to
delivery, we really do all care.
6. Suggestions and Comments
We love customers and love to hear from you whether it's feedback
or questions about our Quality, Service, Market, etc, we will
continue improving our performance and together we are stronger.
