Neodymium Price Increase Explanation Letter to Valued Customers Dear Valued Customer, You may already feel that recently our prices for Rare Earth Neodymium magnets have increased quickly and the validity of price is shortened. We understand this may have caused inconveniences. However, we think it’s necessary to explain the current situation and also express our [...]
The Effect of Environmental Protection Inspection on Magnet Industry The Environment Protection Inspection Team sat off the nationwide environmental storm since last year. Unlike the previous environment renovation, the emphasis and intensity of Environment Protection Inspection is unprecedented this time. For magnet industry, the supply of rare earth element is also affected and eventually it [...]
40 Years Later No Fe16N2 Magnet – Why? • Difficult to synthesize pure Fe16N2 by conventional methods e.g. solubility of N in liquid Fe very low (0.045 versus 5.5 wt % for C). • Alloy cannot be formed by conventional processing methods e.g. melting and casting. • Contradictory results over the years probably due to inconsistent sample preparation and measurement techniques. • Fe16N2 decomposes above 300 C. Fe16N2 Magnet • Cannot be formed by powder metallurgical processing. • Lots of magnetization available but need coercivity for a useful PM compound; theoretical magnetocrystalline anisotropy H is 16 kOe but will need help from other mechanisms e.g. shape, strain. Bulk Fe16N2 Magnet Reported by UMN Team and Niron Magnetics Formed • Strained wire method used to enhance magnetic property; strain‐assisted annealing. Niron Magnetics – Good News • The company is producing bulk iron nitride magnets today for further research and development. • First principles calculations demonstrate a theoretical BHmax of 135 MGOe and Hc of 16 KOe. • Raw materials are cheap and abundant. • Isotropic bonded magnet BHmax > 30 MGOe feasible. Niron Magnetics – Bad News • Iron nitride by itself is inherently heat sensitive. • It decomposes before it sinters – iron nitride magnets will all be bonded in some fashion. • Coercivity needs to be improved. • They will need the same corrosion protection as raw iron. • Niron hasn’t announced a commercial product yet NdFeB Segment Magnets [...]
TESTING MAGNET Because magnetic fields are transparent to the human eye, measuring their strength requires specialized tools that measure the working air gap of the magnetic circuit. Currently there are two accepted ways of testing your magnetic separation equipment and this subject itself is not without controversy. The first is with the use of an [...]
MAGNETIC APPLICATIONS Magnets magnetically capture and control ferrous contaminants in material process systems. Primary Magnets Primary magnets are designed to be used in high volume process flows placed inline so as not to introduce any foreign contaminants from external sources into your production facility. They will remove large amounts of ferrous tramp between cleaning cycles [...]
Magnetic Circuitry is simply how the magnet is designed to attract and retain ferrous contaminants. MPCO utilizes 3 magnetic circuits; Type A, Type B, and Type C. Type A Circuitry Type A circuits can be used in applications where the highest level of product purity is required. The circuit utilizes a tube, or a series [...]
Electromagnetic Sheet Fanners Electromagnetic Sheet Fanners eliminate die-damaging, double-blanking problems in automated sheet handling operations. A powerful electromagnetic field automatically separates the sheets. As fast as the top sheet is removed, the next sheet instantly moves up. The on/off capability of the Electromagnetic Sheet Fanners provide operator safety during steel blank stacking and un-banding. This [...]
Radical new maglev elevators that travel in ANY direction could lead to super skyscrapers far taller than today's buildings Technological innovations have allowed us to build skyscrapers to great heights But people still don't live in skyscrapers the way futurists had envisioned This is because elevators are only able to go up and down, and [...]
Test Tower for Futuristic Magnetic Elevators Nears Completion Elevators that can go up and sideways look set to be the way of the future thanks to German engineering firm ThyssenKrupp. ThyssenKrupp stated recently in a press release that after 10 months of construction they’ve almost finished building the exterior of a massive 761-foot concrete tower [...]
China Rare-earth Trafficking Out - Despite a two year campaign directed at cleaning the sector and removing all illegal operations, China has known that its rare earth industry still suffers seriously from pollution, smuggling as well as illegal mining. Rare earth elements provide lively functions in all modern day technologies, and China holds an almost [...]
Do you know Wind Turbine Permanent Magnet? Since the first oil crisis in 1973 and the radiation leak at Fukushima in 2011, more and more eyes on wind power. For example, affected by the nuclear leakage accident in Japan, Germany will plan to abandon nuclear power to generate electricity completely. And the same time, strive [...]
