The price of the rare earth oxide neodymium oxide was 49,763 U.S. dollars per metric ton in 2020. By 2030, the price of neodymium oxide is expected to increase to 45,500 U.S. dollars per metric ton.
How much does neodymium cost per kg?
The price of neodymium doubled in the third quarter of 2017 to $ 76 per kilogram compared to the beginning of the year. Neodymium thus experienced the strongest price increase among the 15 most important rare earth metals in the past year.
Are neodymium magnets expensive?
Neodymium magnets are relatively more expensive than ceramic magnets. They rust very easily, and extra steps must be taken to protect them from corrosion. Neodymium magnets are also very brittle and will crack under stress.
Why is neodymium expensive?
The price of neodymium magnets, so-called „super magnets“, is comparatively high compared to other types of magnets. This is because the raw materials required for this (including neodymium) are almost exclusively mined in China. The country can therefore set the price and reduce the available quantity.
What is the price of rare earth?
The price of rare earth praseodymium – used in magnets for EVs, smartphones and military equipment – has more than doubled over the past 14 months to about $102 a kg. This compares to a peak of about $250 a kg in August 2011 after dominant producer China threatened to clamp down on exports.
Can I buy neodymium magnet?
Neodymium magnets are available for sale in a variety of shapes, sizes and grades. Neodymium magnets are brittle and should be handled with extreme care to avoid personal injury and damage to the magnets.
Do neodymium magnets rust?
Neodymium magnets are so prone to corrosion, that even the moisture in the atmosphere can cause them to corrode over time. The typical coating for a neodymium magnet is a layer of nickel followed by a layer of copper and then nickel again. However, there are a variety of different coatings available.
Are neodymium magnets illegal?
The powerful magnets were banned in 2013, but the rules against using them in toys were lifted in 2016, leading to more emergency room visits.
What magnet is stronger than neodymium?
Iron Nitride Permanent Magnet Stronger than Neodymium Magnet.
Can neodymium magnets damage electronics?
The strong magnetic fields near neodymium magnets can damage magnetic media such as floppy disks, credit cards, magnetic I.D. cards, cassette tapes, video tapes or other such devices. They can also damage televisions, VCRs, computer monitors and CRT displays. Avoid placing neodymium magnets near electronic appliances.
Why does China have all the rare earth metals?
Production quotas were instigated for the miners and oftentimes quotas would be surpassed because of illegal mining by people who did not have licenses. The Chinese government was also able to use these rare earths as a means of exerting power over other countries.
How much do magnets cost?
13.0. 1 What do magnets cost?
| Material | BHmax (MGOe) | Relative Cost |
|---|---|---|
| Ceramic | 3 | $2.00 |
| Alnico | 5 | $20.00 |
| SmCo | 25 | $70.00 |
| NdFeB | 40 | $35.00 |
Why are super magnets so strong?
The pull strength a neodymium magnet can achieve is the strongest of the permanent magnets you can buy. It is so strong because it has a very high state of saturation, magnetization. So, the magnetic energy the combination of neodymium, iron, and boron can store, makes the alloy very magnetic.
What’s the cost of dysprosium?
In 2020 the price of dysprosium oxide was 260 U.S. dollars per kilogram. There are 17 rare earth elements and although they are fairly abundant in the Earth’s crust, often they occur at sparse intervals are are less economically exploitable.
What does Lynas mine?
Lynas is the world’s second largest producer of neodymium (Nd) and praseodymium (Pr), both light rare earths. Used together, they form NdPr, an alloy that’s present in a magnet inside the iPhone. Lanthanum (La) and cerium (Ce), two other light rare earths, make up over 70% of the Mt. Weld reserves.
Which country is famous for its rich deposits of many rare minerals?
China
1. China. Unsurprisingly, China has the highest reserves of rare earth minerals at 44 million MT. The country was also the world’s leading rare earths producer in 2020 by a long shot, putting out 140,000 MT.
Where can I get neodymium?
Neodymium is fairly common, about as common as cobalt, nickel, or copper, and is widely distributed in the Earth’s crust. Most of the world’s commercial neodymium is mined in China, as with many other rare-earth metals.

What’s the strongest magnet I can buy?
neodymium magnet
The neodymium magnet is the strongest type of magnet you can buy. They’re permanent magnets and also referred to as power magnets which of course hint to their extreme power.
What is the most powerful magnet on Earth?
The strongest permanent magnets in the world are neodymium (Nd) magnets, they are made from magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure.
Can neodymium magnets damage cell phones?
Will the magnet hurt my phone? We still get asked every day — “Will a magnet hurt my phone?” The simple answer is “NO.” Apple iPhone and Android devices use NAND flash memory, which is immune to magnets.
How long does neodymium magnet last?
100 years
How long will a neodymium magnet last? Neodymium magnets are permanent magnets, and lose a fraction of their performance every 100 years if maintained within their optimum working conditions.
