Neodymium Magnets China Manufacturer Custom Neodymium Arc Shaped Magnets
Arc magnets are mainly used in permanent magnet DC motors. Unlike electromagnetic motors that generate magnetic potential sources through excitation coils, PM motors use permanent magnet materials to generate constant magnetic potential sources. Instead of electric excitation, permanent arc magnets have many advantages, which can make the motor simple in structure, convenient in maintenance, light in weight, small in size, reliable in use, low in copper consumption, and low in energy consumption.
Standard Neodymium Magnets
Neodymium magnets (also known as Nd-Fe-B) is one type of rare-earth permanent magnet. And it is an important component for electric vehicles, house appliances, robots, garden tools, medical equipment, etc.
AH Magnet is specialized in researching, developing, manufacturing and exporting high-performance sintered neodymium iron boron magnets, 47 grades of standard neodymium magnets, from N33 to 35AH, and GBD Series from 48SH to 45AH are available. All magnets are widely applied to electric motors such as servo motors, stepper motors, brushless motor, linear motors, permanent magnet synchronous motors, etc.
Aim to increase the corrosion resistance of sintered neodymium iron boron magnets and to meet the designated surface requirements, we provide the normal coating layers, like nickel-coating, zinc-coating, epoxy-coating, aluminum-coating and passivation. We also customized composite coating to ensure durability of magnets according to different design and application environment of permanent magnets.
Find the suitable NdFeB to meet your design requirements from the following sheet and download the related files. And FIVE important keys should be considered when you choose from these grades.

As we know, the neodymium iron boron magnets contain 64-66% iron, so it is prone to be corroded and oxidized if coatings are not adopted. Both appearance and magnetic properties of uncoated high performance neodymium magnets would be affected under high temperature, acid condition, alkaline environment, seawater, etc. All in all, coating is necessary to magnets.

Rare earth magnets are very strong magnets made from alloys of rare earth elements. They are the strongest among the permanent magnets made. These magnets can be manufactured through sintering, compression bonding, injection molding, and extrusion.
Since their prices became competitive in the 1990s, rare earth magnets have been replacing Alnico and ferrite magnets in many applications in modern technology requiring powerful magnets. Their greater strength allows smaller and lighter magnets to be used for given applications that require high strength. The material is easily magnetized in one direction, but is able to prevent magnetic pull in any other direction.
As a professional magnets manufacturer, AH Magnet is committed to supplying neo magnets with normal and complex shapes. The normal magnet shapes are ring, block, round, disc, are, horeshoe, cylinder, sphere, etc. And, the most suitable magnets should be prpduced according to customers designs, click to learn about custom rare earth magnets.
About this Item
Although NdFeB magnet is a kind of hard and brittle material, we can customize some complex shapes according to customers requirements. We have produced some complex shapes such as different heads, convex, concave, slotted, side punched, cut corners, non-semi-circular and countersunk magnet.
Different fixtures are needed when make complex samples and mass production. However, we always waive the cost of fixtures once the minimum order are USD100.
We do not set MOQ, maybe 1-5 pieces are also feasible, because the order amount is more calculated based on the magnetic properties and the difficulty of production.
What are the Different Types Of Rare Earth Magnets?
There are two types of rare earth magnets, Neodymium and Samarium-Cobalt. Their shapes can include arc, block, cube, cylinder, disc, rod, sphere and many more. You can browse through our current shapes and sizes to find the right magnet for your application. If you need a custom design, we can work with you to create unique specifications for all shapes and sizes. Contact AH Magnet, an industrial rare earth magnet manufacturer, to find out how we can help provide you custom rare earth magnets.
What are some of the main differences between Neodymium magnets and Samarium-Cobalt magnets?
When deciding between Neodymium Magnets and Samarium-Cobalt Magnets, there are key differences to consider before you make your decision. Some of the main difference between the two types of rare earth magnets are:
Advantages of Each Type of Rare Earth Magnet
Neodymium magnets have the highest energy product of any material, and this type of magnet is known for its ability to be created in a wide range of available shapes, sizes, and grades.
Material: sintered ndfeb magnet
Grade: N48
Dimensions: 2" L x1" W x 1/2" T
Tolerances:
Plating/Coating: Ni-Cu-Ni (Nickel)
Magnetization Direction: Axial (through 1/2")
Max Operating Temp: 176oF (80oC)
Application: Wind Turbine
Since the first oil crisis in 1973 and the radiation leak at Fukushima in 2011, more and more eyes on wind power. For example, affected by the nuclear leakage accident in Japan, Germany will plan to abandon nuclear power to generate electricity completely. And the same time, strive to develop new & Renewable Energy, such as wind power and solar energy. Refer to wind power, magnet which plays important role in wind turbine generator to generate power cannot be ignored.
At present, the magnet which used on wind turbine alternator is Sintered NdFeB magnet (Commonly known as magnet king, permanent magnet, rare earth magnet);
The common grades are N42, N48, N50, and N38SH and so on;
The common shapes are segment, block, wedge, and trapezoid;
The coating is Ni-Cu-Ni triple plated
The biggest block magnet for wind turbine generator is about 240x80x40 mm (the thickness cannot over 50mm)
The normal block size is 2 (2 inches x 1 inch x 1 inch)
China also develops wind energy rapidly these years. In 2011, there is half Wind Power Equipments for the whole world made in China. In this field, China is ahead of Germany and USA, and dominates the industry. This mainly depends on domestic magnet manufacture. Recently, considering high cost in purchasing wind turbine from China, many customers plan to purchase accessories and material and make wind turbine by themselves. Of course, this includes magnet purchase from China.
China magnet source care customers benefit and will provide Wind Turbine Permanent Magnet with good quality, reasonable price; to satisfy customers requirement in making family-type or industrial wind turbine.
