Neodymium Powder Buy

There are a couple questions here. Will it retain its magnetism? Can I add the powder to the iron powder currently in my "magnetic" silly putty to make it truly magnetic? And finally, how best do I crush it? The magnet that came with the putty has chipped so I'm willing to sacrifice it in the name of recreational science.

I recently had the same question. I took a couple of my neodymium magnets (small) and I proceeded to crush them with a steel hammer. No need to watch where the pieces went, they stayed stuck to the hammer head. The pieces maintained their magnetic pull to one another, but lost more and more the finer the crushed pieces got. I got it near to a powder, with some slightly larger pieces, and they were sticking together, but not as strong as I had hoped for a project I am working on.

When you crush the magnet it just becomes smaller pieces of magnet, so I believe the individual granules should still retain their magnetism. However, the directions of the poles of the magnet granules when put would be just cancel each other out... (because they are in a mess in your powder form with some granules having poles pointing one direction, another some other direction) so your silly putty would not become truly magnetic.

These strong 40 Lb. magnetic hooks are versatile products that can be placed almost anywhere and hold up almost anything with ease. Unlike weaker magnetic hooks that slip and slide everywhere, these magnetic hooks are made of strong neodymium magnets are more than powerful enough to hold things still. If attached to a smooth, clean metal surface, these magnets can even be used in permanent applications with plenty of holding power to spare. If being attached to delicate surfaces that are easily scratched, then a thin layer of fabrics, plastics can be placed in-between the magnet and the surface.

Unlike other plain finished magnetic hooks, the high-quality powder coating of these hook provides an effective weatherproof coating and nice looking. These hooks also blend in well with their surroundings and make for a great temporary anchoring point for banners, posters, string lights, or other objects.

Are you looking for an easy way to attach utensils to magnetic surfaces? The neodymium magnetic tape impresses with the fact that it adheres bombproof, but at the same time can be easily attached and removed. In addition, it is elastic and therefore extremely flexible. It can therefore easily be attached in narrow cracks - for example between window and frame - but also on any other surface.

The neodymium power magnetic tape is extremely versatile, easy to cut to size and removable and can be helpful in a wide variety of areas. For a long time, magnetic foils and tapes could only be made from ferrite. However, these only have a fraction of the adhesive force of neodymium magnets.

As the demand for stronger adhesive material has increased over the years, neodymium power magnetic tape has therefore been developed, which has a holding force or adhesion of up to 415 g / cm. With ferro-band magnets, however, this is only about 102 g / cm. Neodymium magnetic strips are therefore four times as strong on average.

Our neodymium magnetic tape is well suited if you have smaller or larger items on your home refrigerator, a metal shelf or something similar that you want to attach. The metal surface should only be flat and not bulged or very scratched. If the wall is uneven, the adhesive force of the tape can be greatly reduced.

The neodymium magnetic tape is available in different lengths and widths. You can choose freely from 6 to 80 mm, depending on your needs. It is available in lengths of 1 and 10 meters. If you want to glue larger areas, use our power magnetic foil. These are available in the following dimensions:

All of our products are ready for immediate dispatch and can be delivered within a very short time (approx. 1 - 3 working days). If you have any further questions about our neodymium magnetic tapes, take a look at the product information.

For a more flexible alternative to sintered neodymium, consider using bonded neodymium magnets for your application. Bonded neodymium powder is used to create these magnets. Powder is melted and mixed with a polymer. Components are then pressed or extruded to create the product. Bonded Neodymium magnets can be magnetized into complex patterns with multiple poles. Though much weaker than Sintered Neodymium magnets, Bonded neodymium magnets give greater flexibility in terms of shapes that can be made. They are also lighter than Samarium Cobalt, and have a lower acceptable temperature (coercivity). Nevertheless, they offer excellent value for applications that require a smaller magnet or utilize radial rings.

Bonded neodymium-iron-boron (NdFeB) magnets are strong magnets which are used for various applications. Epoxy coating is mostly common used for bonded NdFeB magnets; electroless nickel plating is also used to prevent corrosion. Isotropic bonded NdFeB material can be magnetized in any direction, or with multiple poles.

Neodymium has been used since the early 1950s in different products to create magnets with higher magnetic properties than those made with iron or other metals. Neodymium magnets are typically composed of neodymium iron and boron. Combining these two elements produces a powerful magnet that can permanently carry up to 1,300 times its own weight and that is used in a wide range of products ranging from fridge magnets to aircraft engines.

Using neodymium magnets for storing data on computer hard drives and assembling mobile phone speakers and microphones enables the miniaturization of electronics making items like computers and cell phones easily accessible to us today.

Neodymium is also increasingly being utilized in alternative energy sources like wind turbines and electric & hybrid cars, the latter being the biggest user of high-performance neodymium-iron-boron magnets today. At the same time, this rare earth element is also incredibly valuable in medical equipment, including MRI machines, surgical lasers, and heart pacemakers.

Neodymium is rarely found in nature as a free element, instead occurring as ores, such as bastnasite and monazite, that contain small amounts of all rare earth metals. While world reserves of neodymium are estimated at 8 million tonnes, the difficult and potentially environmentally damaging extraction makes this strategic metal so valuable.

The main mining areas are in China, the United States, Brazil, Russia, Sri Lanka, India, and Australia. Most of the current neodymium production (estimated at over 85%) is from China.

We mentioned that neodymium is used in many products and applications, from electric motors, computers, and specialized medical instruments to holding objects together, such as clasps for shoes, fridge magnets, and jewelry.

In the automotive industry, it has become increasingly popular as a component of electric & hybrid cars due to its low cost and high-performance benefits. Considering that each Toyota Prius reportedly contains as much as 1 kg of neodymium in its motor, it is clear the demand for neodymium from this industry alone will increase exponentially over the next 20 years.

So, with the demand expected to soar over the next 20 years (5-fold by 2030 alone, according to EU estimates) and the restricted supply for the foreseeable future, the price of neodymium is expected to keep increasing in the short, middle, and longer term.

Corporate buyers like Tesla, Honda, Ford, Rolls-Royce, and BMW only use licensed metal dealers, like ourselves, to purchase the industry-grade neodymium they need in their production process. We act as a key intermediary between the producers of strategic raw materials and the industry users.

Random Lasing is reported for the first time in Nd3+-doped lead-germanate glass powders. Above laser threshold (0.3 mJ/mm2) a short pulse, in the nanosecond range is observed corroborating the lasing process. 041b061a72
