The price of rare earth is related to supply and demand. China’s rare earth supply accounts for 60%/80% of the world’s share. Under the influence of China’s continued restrictions on the import of rare earth mineral products, restrictions on the import of mineral products in Myanmar, and the addition of 25% tariffs on rare earth

The Earth is a huge magnet. Billions of positively charged atoms produce negatively charged electrons, which spin around the core of an atom and create a magnetic force, transforming the fragment into a minuscule magnet. The substance is more or less magnetized in the external magnetic field, except that the degree of magnetization is different.

Why magnets are an easy fragment NdFeB magnet made up of neodymium, boron, iron. As you know, Boron is the most powerful of magnetic materials. The materials decide magnets is hard and fragile. When process through alloying, crushing, powdering, pressing the magnetic orientation, sintering, NdFeB magnets will lack flexible. Add boron, the magnetic will more

As we all know, neodymium magnet .made up of Neodymium, Iron and Boron, has the strongest magnetic.but the magnetic will turn weaken or disappear of the strength during use. Some customer will confuse, what happens? There are some reasons as following to conduct the magnet demagnetization,   1, injection.some magnet will use in inject the product.

Magnets are natural magnetite. It is a rock mineral and one of the main iron ores, with the chemical formula. The ancient Greek and Chinese found a kind of naturally magnetized stone in nature, called it “magnetite.” this kind of stone can pick up small pieces of iron and point in the same direction after randomly
