The ** of the magnet is judged according to its own composition. Magnets are generally made of ferrite (ferric tetroxide), as well as iron-cobalt-nickel alloys, rare earth alloys of iron and other permanent magnet materials, such as alniccot, samarium cobalt, and neodymium iron-boron. At present, the magnet in the market has soared, mainly because a kind of "rare earth" is controlled by the state, and the purchase channels and volume have been greatly reduced to a certain extent.
From 200,000 tons a year ago to 1.6 million tons at present... Japan exports rare earths at a high rate, as exports have been greatly reduced due to the impact of the Fukushima incident. What are rare earths?
The rare earth family is 15 elements from the lanthanide series, plus scandium and yttrium, which are closely related to the lanthanide series, for a total of 17 elements. They are: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, yttrium.
They are combined with other elements to form a variety of new materials, and the performance is doubled, and it is called the contemporary "industrial monosodium glutamate" and is widely used.

This is calculated by the fact that the ** of raw materials fluctuates every day, and it is necessary to calculate processing costs, management fees, packaging fees, etc.

This is a complicated issue, and I can't explain it in a sentence or two.

What type of magnet do you want, what use, what special requirements?

Summary. Hello, after inquiring about waste magnets, the ordinary kind is 100 yuan kg, the price of NdFeB strong magnetism is 220 yuan kg, and the samarium cobalt strong magnet is more than 100 yuan per kilogram.
Hello, Ye Zhengzheng inquired about waste magnets, the ordinary kind is 100 yuan kg, NdFeB strong magnetic back to the lead price of 220 yuan kg, samarium cobalt strong magnetism per gong song is more than 100 yuan.
There are five types of magnets, including ferrite magnets, iron-chromium-cobalt magnets, alnico magnets, shirt-cobalt magnets, and neodymium-iron-boron magnets. The above five types of magnets are the most commonly used magnets for chain cherry blossoms, of which the first three are ordinary magnets, and the last two are strong magnets. The iron-chromium-cobalt magnet is a permanent magnet alloy material, which contains molybdenum, vanadium, titanium, copper, silicon and other elements, of which the chromium content is 20%-33%, the cobalt content is 3%-25%, the copper content is 3%, and the content of other metals is about 1%.
The strong magnetic material is relatively high, and it has become a popular alloy magnetic material in the market. The general magnet is received by the market coldly, in a state of no one, like the ordinary black magnet in daily life. Generally, these materials are not, and they are used to distinguish whether the metal material is magnetic or not, whether it is iron or copper and aluminum.
In fact, every type of metal on the market is high, on the one hand, it is the lack of its material, and the material is rare and expensive, and on the other hand, it depends on whether it is popular in the market. Hall eggplant at a certain period of time to fry a certain type of metal, its market is high, if the market is cold, its **will**. This is a kind of market regularity.

Summary. Kiss, waste magnets are at 30-40 yuan a catty.
Kiss, waste magnets are at 30-40 yuan a catty.
Black or brown is the earliest ferrite magnet, this is worthless, no one, if it is white, it is a NdFeB magnet, the price is about 70-80 yuan kg. When the changing current enters the speaker, the magnet becomes an electromagnet. The direction of the current is constantly changing, and the electromagnet is constantly moving back and forth due to the "energized wire moving under force in the magnetic field", which drives the paper cone to vibrate back and forth.
What can waste magnets doUse waste magnets are generally useless, but they can be processed as toys or used in other handmade works, or as metals in the garbage. In this way, the waste magnets will be reused in other places. In addition, metal products, canned food boxes, etc. can also be put according to the ** items.

Summary. How much is a pound of waste magnets: pro waste magnets are 220 yuan a kilogram, for example, the ** price of NdFeB strong magnetism is 220 yuan per kilogram, and the strong magnetism of samarium cobalt is more than 100 yuan per kilogram.
How much is a pound of waste magnets: pro waste magnets are 220 yuan a kilogram, for example, the price of neodymium iron boron strong magnetism is 220 yuan kilogram, and the strong magnetism of samarium hand friend cobalt is more than 100 yuan per kilogram.
What kind of magnet does this belong to?
Scrap magnets.

Summary. Hello dear! Expand on that for you, <>
<> about 30 to 50 yuan, black or brown is a ferrite magnet, this is worthless, if it is white, it is a NdFeB magnet, the price is about 70-80 yuan kg. The average purchase of the current domestic strong magnetic market is 120 yuan to 150 yuan per kilogram, and when the strong magnetic buyer completes the purchase, these strong magnetic resale will be resold to some designated manufacturers, ranging from 180 yuan to 220 yuan.

Summary. Good afternoon, dear We are happy to serve you and find out the waste magnet at 30-40 yuan a pound for you. Black or brown is a ferrite magnet, this has no value to anyone**, if it is white, it is a NdFeB magnet, the price is about 60-80 yuan kg.
If it is a NdFeB permanent magnet, then it is about 50 yuan per kilogram in the market now, I hope my answer will be helpful to you!

The ** of a pound of waste magnets is as follows:
It depends on what kind of magnet it is. If it's ferrite, it's not worth much. If it is aluminum, iron and boron, it is about 100 yuan kilogram according to the current Qinwu **, and if it is aluminum-nickel-cobalt, it is about 50 yuan kilogram.

Basic knowledge of waste magnets:
Waste magnets belong to the best things. Magnets are included in scrap metals, paper, plastics, fabrics and other recyclable household garbage, and magnets are included in scrap metals, so they belong to the world.
The scientific name of the magnet type is magnet, and the metal substance can be reused. Magnets are widely used in life, mainly used in electroacoustics, permanent magnet motors, communications, automotive electronics, magnetic machinery, aerospace, computers, household appliances, medical equipment, Zheng Shoubo office automation and other fields. <>

Magnet ** at 70 yuan a pound.
Magnets can be divided into "magnets" and "non-magnets". Magnets can be natural products, also known as natural magnets, or they can be artificially manufactured. Non-sexual magnets, such as electromagnets, only appear magnetic under certain conditions.
Magnets are capable of generating magnetic fields and have the property of attracting ferromagnetic materials such as iron, nickel, cobalt, and other metals.
Applications of magnets:
1. Electroacoustic device: mobile phone, TV, stereo, headphones and other sound-generating speakers, this kind of speaker is a device that converts electrical signals into acoustic signals.
2. Electronic devices: dormant holsters for mobile phones and tablets, etc.
3. Many items such as bags and holsters use magnets to adsorb and fix.
4. Medical field: the most commonly used nuclear magnetic resonance in medical examinations. It is to use the magnetic field of the human body itself and the magnetic material carried by the instrument and the hand device itself to interact to form a detection and development to help people find the cause of the lesion.
Similarly, in other medical treatments, there are also many traces of the application of magnets, such as acupuncture and moxibustion magnetic therapy, magnetic detector early grip, etc. <>
