Neodymium Magnets

https://www.rishengmagnets.com/products/neodymium-magnets.html

Neodymium magnets (also called NdFeB magnets, Neo magnets) are consisted of Nd (neodymium), Fe (Ferrum), B (boron), and other elements like Dy (dysprosium) and Ti (Titanium). As part of the permanent magnet family, they are the latest generation of rare earth magnets. Neodymium magnets are extremely super strong magnets commercially available in the world, their pull force are quite strong compared to their own size, they have high magnetic remanence, high energy product and relative good coercive, due to these advantages, they are the most widely used magnets today.

 As a reputable neodymium permanent magnet manufacturer in China, RiSheng has various types of powerful magnets for sale, in our online shops and physical stores, with competitive price per kg, very cost effective. In terms of the size, our factory supplies not only the small series— paper thin, micro, tiny, mini, but also the big ones—large, huge, giant monster. Considering practical applications, we provide customized neodymium magnets. They are of different shapes: arc, rod, bar, ball, ring, disc, flat, block, sphere, eclipse, curved, bonded, rectangular, cylindrical, with countersunk holes; and are for different purposes and industrial uses: for cutting, drilling, grinding, machining, for therapy, water meter, etc. Some of them can be sintered, silicone coated, some can be made super strong, adhesive, waterproof. For the convinience of our customers, Risheng has already prepared relevant pdf files and videos about neodymium magnets. Contact us immediately, get cheaper price with best service.

 Physical Properties Of Neodymium Magnets

A few main physical properties are listed, like density, curie temperature, etc.

 Physical properties of Neodymium Magnets

 Sizes & Tolerance Of Neodymium Magnets

We can produce different shapes, like a disc, cylinder, ring, arc segment, and custom complicated shapes, a wide range of sizes are possible with a few limits.

 The standard tolerances are generally +/-0.1mm, while slightly varies depending on how big the size is.

 Sizes & Tolerance of Neodymium Magnets

 Magnetization Of Neodymium Magnets

All Neodymium magnets are anisotropic and oriented with a preferred direction during production, they can only be magnetized thru the oriented direction. Disc/cylinder/ring magnets are axially or diametrically magnetized, block magnets are magnetized along one side of three sides, arc segment magnets are generally diametrically magnetized.

 Magnetization Of Neodymium Magnets

 Surface Coatings Of Neodymium Magnets

The corrosion resistance of Neodymium magnets is considered very poor, a surface coating will be necessary, the most common coatings are NiCuNi, Zn, Black Epoxy, Teflon/PTFE, Rubber/Plastic.

 Surface coatings of Neodymium Magnets

 Manufacturing Method Of Neodymium Magnets

Neodymium magnets are made by a sophisticated process using very advanced metallurgical methods, the main process is Rare earth raw materials - Quick curing - Strip casting - Hydrogen decrepitation - Milling - Pressing - Sintering - BH curve testing - Machining - Plating - Magnetizing - Packaging.

 Manufacturing Method

 Applications Of Neodymium Magnets

Neodymium magnets are widely used for industrial, technical, commercial, and consumer applications, the most common applications are motors/generators, sensors, audio equipment, holding/lifting systems, magnetic bearings, hard disc drives, levitation devices, magnetically coupled pumps, medical devices, magnetic separators, packaging closures, commercial signage/display.

U/C Channel Magnets

https://www.magnetic-holders.com/products/c-channel-magnets/

Different from a normal cup(pot) magnet, the U-channel holding magnet is not round-shaped, and it is rectangular bar shape. The composition structure blocks bar magnets housed in a u-shaped steel shell. The magnetic adhesive force of the block bar magnets is significantly enlarged by the steel shell, meantime the block bar magnets are protected by the steel shell and avoid being damaged.

 U-channel holding magnets are especially suitable for carpentry, kitchen installations, exhibition stand construction, shopfitting, signage technology, etc，and used as rectangular base magnets. To make it easy to be mounting, the u-channel holding magnets are made with one or two countersunk holes for screws according to the length. Usually, neodymium block bar magnets with countersunk holes and ferrite(ceramic) block bar magnets are used to assemble U-shaped screw-on holding magnets(magnetic holder). The neodymium channel magnets are for heavy-duty application, and the ferrite channel magnets are for lighter-duty application. Choose it according to your application to save unnecessary costs. Channel magnets can be used in both indoor & outdoor applications, they are ideal for industrial & consumer mounting holding & fixing applications where high-magnetic strength is required.

  The Application Of U/C Channel Magnets

Neodymium(ferrite) U-channel screw-on magnets are mainly used for holding or mounting heavy-duty applications.

neodymium (ferrite)U/C channel magnets commonly used a magnetic tools holder in repair factory of the automobile industry.

Neodymium(ferrite) U/C channel magnets can be used as magnetic door catcher

neodymium(ferrite) U/C channel magnets can be used as magnetic vehicle license plate holders

neodymium(ferrite) U/C channel magnets can be used as magnetic blueprint holders

Neodymium(ferrite) U/C channel magnets can be used as magnetic  sign and banner holders
