Buy Big Neodymium Magnets ((HOT))

Big Neodymium Magnets are commonly known as huge magnets, or giant magnets. They are industrial magnets with dimensions greater than 150mm, widely used in large fans, motors and large robots because of their strong pull force and magnetic field.

The cost of heavy duty magnets are very high, and the delivery time is long. For customers who are in the research and development stage, we recommend customers ask magnets manufacturers if they have any similar size in stock. This will save costs and time.

The price of big neodymium magnets is higher than that of the smaller magnets sold on amazon. Because they are large and difficult in processing. There are many factors that affect the price, among which the most important are:

The magnet is larger means that more raw materials are required for production. The main raw material is neodymium, a rare earth element. Therefore, larger lead to higher prices. Large also means that production is more difficult than with smaller sizes, which will need special machine and magnetizers.

Osenc is one of the few Chinese companies that can supply large magnets. We provide large NdFeB magnets for many large European and American companies. There are fewer than 10 factories in China that can produce large magnets with a diameter of 250mm.

If big neodymium magnets are shipped by air or air cargo, it depends on how big they are. People have to wrap them in a lot of iron plates to meet IATA regulations. This would add too much cost. That is why lots of companies suggest customer ship big neodymium magnets by sea.

In our experience, lots of neodymium mangets factories can not ship big magnet well. If only one large magnet is sent, there is only a 30% chance of it being sent successfully. If two magnets are shipped together, there is an 80% chance that they will be shipped successfully. If you would like to know more details about sending magnets abroad, please contact us directly.

Another characteristic of large neodymium magnets that makes them difficult to handle mechanically is the brittle nature of these magnets, which causes them to shatter into many small pieces if impacted.

Normally, when producing a big neodymium magnet, we will definitely prepare a second part just in case. Sometimes the first sample may fail to meet the standard and needs to be re-produced. This leads to a production time of approximately 40-80 days. In most cases though, this takes only 40 days.

The ratio of the weight that magnets of different shapes and sizes can pick up and their own weight varies greatly, some are less than 200 times, some are more than 500 times, and some can reach more than 3000 times, so the 600 times written on the Internet is not completely correct

Osenc focuses on neodymium magnets and magnetic assemblies. We take quality, innovation, and timely shipping as our top priorities. Drop us a line whenever you need a hassle-free supplier for your magnets.

Neodymium magnets are also commercially available under the designation neodymium-iron-boron or NdFeB magnets. Neodymium is one of the so-called "rare earths". The special and difficult thing about these metals is not their rarity, but the complicated extraction and release from other compounds. Accordingly, neodymium magnets are quite expensive compared to other magnets. But they are among the strongest magnets in the world - and this is already the case with small models of just a few centimeters. Before you buy neodymium magnets, you should think about the shape that is ideal for you. We carry:

Industry and hobbyists rely on an effective force that is many times greater than that of ordinary magnets - for example compared to ferrite magnets. New technologies ensure that the heat point at which neodymium magnets lose their magnetism has already shifted far upwards. Scientists assume that both the magnetic force and the hot spot can even be significantly improved soon. In this respect, neodymium magnets are not only ultra-strong, but can also be used at full power under extreme conditions - such as high temperatures in industrial plants. Branches of industry such as PC and mobile phone manufacturers, engine workshops and high technologies are now unthinkable without neodymium magnets. Hard drives run faster, speakers perform better, it all works because of a small magnet with superpowers.

We also refer to neodymium magnets as super magnets because their adhesive force is much stronger than that of ordinary ferrite magnets. Some hold six hundred times their own weight. This can be measured using the energy density, which is given in kilojoules per cubic meter (kJ/m). Ferrite magnets usually have an energy density of around 30 kJ/m. Neodymium magnets, on the other hand, have a density of up to 500 kJ/m. This makes them real super magnets.

Otherwise, you can tinker with neodymium magnets or come up with neat gimmicks. Find your bunch of keys with a rodmagnet or place cubemagnets, blockmagnets or spherical magnets in different sizes on a shelf as decoration. You can also pick up metal shavings and sewing needles with magnets or take a walk and see what sticks to your discmagnets.

In our shop you can buy different variants of neodymium super magnets. The advantage of self-adhesive magnets is that they stick to almost all surfaces.You peel off the protective film, stick on the adhesive part and the remaining magnet parts stick together while the permanent magnet is firmly in place. You may be familiar with neodymium ring magnets from doctor's surgeries - they are used there in MRT machines. You can easily cut neodymium magnetic tape and attach various things to the wall, fridge, cupboard, or various other surfaces. Otherwise, the different widths, heights and diameters of the magnetic powerhouses are suitable for many possible applications.

The large and small strong rare earth magnets rust comparatively quickly. This is due to their high iron content. To prevent this, most models are provided with a coating. In humid environments, for example, epoxy coatings and rubber coatings have proven their worth. It is important that the coating is and remains intact. For example, if you handle neodymium magnets improperly - for example, let them hit or rub against each other - cracks can appear in the coating. Therefore, always check which magnets are suitable for which purposes.

When neodymium magnets demagnetize depends on the magnetization quality. With the most common grade N45, the maximum temperature is around 80 C. If the magnet gets warmer, the magnetic properties are lost.

Neodymium magnets are the strongest magnets in the world, so you should handle them with care. Small children should not be allowed near the magnetic metals, as small models can be swallowed. This can be extremely dangerous. Neodymium magnets are not directly poisonous, but if several of them stick together in the intestine, for example, this can lead to life-threatening complications. As with other magnets, there is always a risk of catching bruises - for example if you hold your hand between two large disc magnets. Since neodymium magnets are particularly strong, the risk of injury is correspondingly high.

In principle, it is possible to manipulate or stop electricity meters with magnets. Ordinary magnets are usually too weak, but neodymium models are strong enough to break the disc in the meter from the outside. However, the slowdown would only be short-lived and at the same time the magnet would damage the electricity meter due to the heat generated. In addition, electricity providers can usually identify when such a defect occurs. Finally, manipulating the power level is just plain illegal, so you should refrain from doing so.

The simple metallic beauty is not only a joy for figures made of neodymium magnetic spheres. Maybe you also use conemagnets and discmagnets for magic. With small and large neodymium magnets, you can let your imagination run wild. In addition, neodymium magnets make wonderful, unusual gifts. 041b061a72
