Rare earth samarium cobalt magnets, shorted as SmCo rectangular magnet, are a type of powerful permanent magnet made from the basic elements samarium and cobalt and other metal rare earth materials by mixing, melting, grinding, pressing and sintering. They come in various sizes and shapes, like disc,bar, ring, arc,block, etc.,. Similar to neodymium strong magnets, they belong to the rare earth magnet category, and tcan be classified as SmCo5 and Sm2Co17 according the composition ratios of samarium and cobalt.
In comparison to neodymium rare earth magnets, although samarium cobalt magnets may not have as strong magnetic force, they possess two distinct advantages. Firstly, they operate effectively within a higher temperature range, and secondly, they exhibit greater resistance to corrosion.
Due to these characteristics, large smco block magnets are commonly employed in applications that demand high operating temperatures, such as generators, pump couplings, sensors, electric motors, marine applications, as well as in the automotive, racing, aerospace, military, and food and manufacturing industries. SmCo rare earth magnets not only perform well at high temperatures but also maintain their magnetic properties even in temperatures below absolute zero (-273 degrees Celsius), making them popular for use in low-temperature applications.

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. 1.

Walking in a residential area, you will find people sitting on the road side with the billboard of home electric appliance recycling. Japanese is using the recycled aluminum, iron and other resources to build their own "urban mines". Compared with the country which only uses their nature resources, japanese is wiser. The magnetic separator is equipment used on recycling industry to distinguish the ferrous and non-ferrous, copper, aluminum and plastic. Their work mainly depends on the function of magnetic force and alternating magnetic field. There are hard magnet and soft magnet. The magnet used on separator is hard magnet. Hard magnet is classified into five categories: sintered ndfeb, bonded ndfeb, ferrite, samarium cobalt, alnico. Only strong magnetic force can separate metal and non-metal apart. According to this, separator magnet is generally sintered ndfeb. At the same time, to consider magnet cost, big block ferrite is also an option. Samarium cobalt, alnico, and bonded ndfeb are not strong enough on magnetic force and high cost, so don t in considering the scope. The shape of separator magnet is block. Like ferrite, the size is 6 . The size of sintered ndfeb depends on the design of magnetic equipment manufacturer. Every company will choose size and grade of permanent magnet according to their application. 1. To delivery by air or by express: anti-magnetic package (six sides iron sheets in the carton); 2.
