Audited Supplier 1. Product descrition
Neodymium magnets, the correct definition is Neodymium-Iron-Boron (shortcut NdFeB magnets), have the highest adhesion force at smallest volume. These are often referred to as "super strong magnets" or "super adhesion magnets". Hereby Neodymium is a very high quality magnetic material.
Because of the excellent corrosion resistance, Neodymium magnets are used with a nickel coating at the most applications. Other coatings like epoxy are possible as well as gold or parylene. Our stock contains of several kinds of standard Neodymium magnets like block- / bar- / segment- / disc- or ring magnets. We can also offer you special designs according to your specifications/drawings on request.
Neodymium magnets can be used for holding applications, as a closure but also for sensory exertion. We would be pleased to assist you with the development of your application and advise you regarding design, quality, coating and magnetization to create an useful and economical product.
Advantages
Disadvantages
Neodymium magnets are available in several different sizes and variations, including neodymium bar magnets or neodymium blocks, neodymium disc magnets, neodymium pot magnets, neodymium ring magnets. They are also available with attachments such as hooks or threaded attachments. They are also available with rubber coatings or adhesive backings. This gives a vast choice to suit a variety of applications including:-
Some of the different types of magnet coatings are given below:
1) . Ni-Cu-Ni: The three-layer metallic coating of nickel-copper-nickel is the most popular option for neodymium magnets. It is well suited for magnets that are used in indoor products but are less resistant to harsher environments.|

a. Plastic separation will be put between strong and big pot magnets, then customer could be easily separate.
b. Batch magnets will be put in small white box.
c. 8 white boxes will be put in carton size 34x26x20cm.Foam form will be put between white boxes to avoid broken during shipment.
d.If by express or by air shipment,put iron sheet between foam form and external carton to shield the magnetic field.
