On January 18, 1960, Rea Magnet Wire was purchased by Alcoa. Sales manager Robert L. “Bob” Whearley—another Dudlo employee—was named President in late 1960 when brothers Samuel and David Rea left the company. Jim Vann, who had been president of Rea since 1982, joined with several others to buy Rea Magnet Wire from Alcoa.
There are 17 rare earth metals, and their production is a complex multi-stage process. Exports may be in the form of ores or goods at any stage including mined rare earth ores (all containing a tiny mix of rare earths), refined ore concentrates, refined highly pure metals, or products incorporating refined metals (car li-on batteries, magnets or magnet incorporating windmill generators).
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. [30] 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. [31] [9]
The rare earth industry in China is a large industry. Rare earths are a group of elements on the periodic table with similar properties. Rare earth metals are used to manufacture technologies including electric vehicles (EVs), wind turbines, consumer electronics and other clean energy technologies. Rare earth elements are also important to national governments because they are used in the ...
Founded in 1930, is a global provider [4] of magnet wire, used by original equipment manufacturers as well as manufacturers in the automotive, energy, and industrial sectors. In 2020, a global joint venture between Essex Magnet Wire and Furukawa Electric Co., Ltd. was formed and operates under Essex Furukawa Magnet Wire. [6]
Ferrofluid on glass, with a rare-earth magnet underneath. A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements.Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.
China has 34 major ports and more than 2000 minor ports. The former are mostly sea ports (except for ports such as Shanghai, Nanjing and Jiujiang along the Yangtze and Guangzhou in the Pearl River delta) opening up to the Yellow Sea (Bo Hai), Taiwan Strait, Pearl River and South China Sea while the latter comprise ports that lie along the major and minor rivers of China.

An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by a pulse of electric current in a wire winding around part of the magnet. The magnet consists of two sections, one of "hard" (high coercivity) magnetic material and one of "soft" (low coercivity) material. The ...
