Custom different size of NdFeB magnet Ring
NdFeB permanent magnet materies came out in 1980, Are widely used in motor,speaker,toys and electron etc. It's composed of Neodymium,Ferrite,Boron and other trace metals.
Have ultra high magnet performance, maximum magnetic energy product (Bhmax) 10times of higher than Ferrite.have better mechnical performance,can be cut to different shapes and drilling. Its maximum work temperature reach up to 200â??.Due to its element include easy corrosion component , be demanded to different surface coating treatment according to using requirements.( such as Zincification,Nickel Plating,Au Plating, Epoxy Plating etc.)
NdFeB is a alloy magnet composed of Neodymium,Fe,Boror and other trace metal elements. Is the strongest magnet rare earth magnet as far to found. Have very high magnetic energy product ( 8MGOe-55MGOe) and better Coercivity.its manufacturing process is mature, have strict quality assurance,perfect technical service and good performance cost ratio.
We manufacturing and sale top quolity of NdFeB permanent magnet,include the largest size of NdFeB magnet ring in the world !!!

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.

NdFeB Magnet is the most powerful commercially produced magnets.
· NdFeB Magnet has a higher Maximum Energy Product, (BH).max, which can easily reach 30 MGOe and even goes
up to 50 MGOe.
· NdFeB Magnet can replace SmCo Magnets in most cases, especially where operating temperature is less than 80
degrees Centigrade.
· NdFeB Magnet has very high strength.
· Relatively low cost.
· Compared to Alnico and SmCo magnets, relatively easy to machine
