Where are neodymium magnets manufactured?
China
As of 2012, 50,000 tons of neodymium magnets are produced officially each year in China, and 80,000 tons in a “company-by-company” build-up done in 2013. China produces more than 95% of rare earth elements and produces about 76% of the world’s total rare-earth magnets, as well as most of the world’s neodymium.
What are NdFeB magnets used for?
NdFeB magnets are widely used in radar technology, satellite communications, remote control telemetry, electronic tracking, and electronic countermeasures. In addition, magnets are also used in magnetron tubes, magnetron traveling wave tubes, cathode ray tubes, and circulators.
Is it safe to touch Neodymium magnets?
Neodymium magnets are perfectly safe for humans and animals as long as you handle them with care. Some neodymium magnets are strong enough to cause some serious damage to your fingers and/or hands if they get jammed between a strong magnet and metal or another magnet.
How is NdFeB made?
Fully dense Neodymium Magnets (also known as neo magnets, neodymium iron boron, neo, or rare earth magnets) are usually manufactured by a powdered metallurgical process. Micron size Neodymium and iron boron powder is produced in an inert gas atmosphere and then compacted in a rigid steel mold or in a rubber mold.
Can Neodymium magnets cause health problems?
Although they have been used in various diagnostic devices in the health sector and as therapeutic tools, magnets are potentially harmful to the body and pose increased risk of accident.
What are neodymium magnets (NdFeB)?
Neodymium magnets (NdFeB) offer a maximum performance from the smallest magnet volume. They should always be coated to guard against the risk of corrosion – NiCuNi, Zinc, NiCuEpoxy and Gold are popular finishes. There are 55 NdFeB magnets commonly in use.
What is the range of sintered NdFeB magnets?
For sintered NdFeB magnets, there is a widely recognized international classification. Their values range from 28 up to 52. The first letter N before the values is short for neodymium, meaning sintered NdFeB magnets.
What does NdFeB stand for?
Our solution was a dual polarity Neodymium (NdFeB) disc magnet within a ring assembly creating a perfect magnetic circuit with a pull force meeting the specification. Ready to Optimise Your Projects with Magnetic Technologies?
Which neodymium magnets have higher Curie temperature?
Special neodymium magnet alloys that include terbium and dysprosium have been developed that have higher Curie temperature, allowing them to tolerate higher temperatures. The table below compares the magnetic performance of neodymium magnets with other types of permanent magnets. Photomicrograph of NdFeB.
