How do I choose the right 6x2mm disc magnet for my project?
Jul 10, 2025| Hey there! So, you're on the hunt for the perfect 6x2mm disc magnet for your project. Well, you've come to the right place. I'm a supplier of these nifty little magnets, and I've got some insights that'll help you make the best choice.
First things first, let's talk about what a 6x2mm disc magnet is. It's a circular magnet with a diameter of 6mm and a thickness of 2mm. These magnets are super versatile and can be used in a whole bunch of projects, from DIY crafts to high - tech gadgets.
Magnetic Strength
One of the most important factors to consider when choosing a 6x2mm disc magnet is its magnetic strength. This is usually measured in Gauss or Tesla, but for us non - physicists, a simpler way to think about it is how strong the magnet can hold onto other magnetic materials.
If you're using the magnet for a light - duty project like holding a small piece of paper to a fridge, you don't need a super - strong magnet. A magnet with a lower magnetic strength will do the job just fine. On the other hand, if you're working on a project that requires the magnet to hold a heavy object or perform in a high - stress environment, you'll want a magnet with a higher magnetic strength.
At our supply, we offer a range of 6x2mm disc magnets with different magnetic strengths. You can check out our 6x2mm Disc Magnet page to see the options available.
Material
The material of the magnet also plays a crucial role in its performance. There are several types of materials used to make disc magnets, but the most common ones are neodymium, ferrite, and samarium - cobalt.
Neodymium magnets are the most popular choice for 6x2mm disc magnets. They're known for their incredibly high magnetic strength, which makes them perfect for projects that require a strong hold. They're also relatively small and lightweight, which is great if you're working on a project with space constraints.


Ferrite magnets, on the other hand, are less expensive than neodymium magnets. They have a lower magnetic strength, but they're more resistant to corrosion and can withstand higher temperatures. If your project is in a harsh environment or you're on a tight budget, ferrite magnets might be the way to go.
Samarium - cobalt magnets are another option. They have a high magnetic strength and are very resistant to high temperatures and corrosion. However, they're also more expensive than neodymium and ferrite magnets, so they're usually used in specialized applications.
Coating
The coating of the magnet is something that's often overlooked but is actually very important. A good coating can protect the magnet from corrosion, which can extend its lifespan.
Most 6x2mm disc magnets come with a nickel - copper - nickel coating. This coating is durable and provides good protection against corrosion. However, if your project is in a particularly harsh environment, you might want to consider a magnet with a different coating, like epoxy or zinc.
Application
Think about how you're going to use the magnet. Different applications require different types of magnets. For example, if you're using the magnet in an electronic device, you'll need to make sure that the magnet doesn't interfere with the device's functionality. Some magnets can cause electromagnetic interference, which can disrupt the operation of electronic components.
If you're using the magnet in a mechanical application, you'll need to consider the magnet's ability to withstand mechanical stress. For example, if the magnet is going to be subject to vibrations or shocks, you'll want a magnet that's strong enough to hold up under these conditions.
Quantity
Another thing to think about is how many magnets you need. If you're working on a large - scale project, you'll obviously need a larger quantity of magnets. We offer bulk discounts on our 6x2mm Disc Magnet, so it's worth considering buying in bulk if you need a lot of magnets.
Compatibility
Make sure that the magnet is compatible with the other materials in your project. For example, if you're using the magnet to hold two pieces of metal together, you need to make sure that the magnet is attracted to the metal. Some metals, like aluminum, are not magnetic, so a magnet won't work with them.
Testing
Before you commit to buying a large quantity of magnets, it's a good idea to order a sample first. This way, you can test the magnet in your project and make sure that it meets your requirements. We offer sample orders of our 6x2mm disc magnets, so you can try them out before making a big purchase.
Comparing with Other Sizes
You might also be wondering how a 6x2mm disc magnet compares to other sizes. For example, the 4mm X 2mm Disc Magnet is smaller in diameter. If you're working on a project with very limited space, the 4mm X 2mm disc magnet might be a better choice. However, it will also have a lower magnetic strength compared to the 6x2mm disc magnet.
On the other hand, if you need a stronger magnet and have a bit more space, you might want to consider a larger - sized disc magnet. You can explore our Disc Magnets page to see the different sizes and options available.
Pricing
Pricing is always a factor when making a purchase. The price of a 6x2mm disc magnet can vary depending on its magnetic strength, material, coating, and quantity. As I mentioned earlier, we offer bulk discounts, so buying in larger quantities can save you money.
It's also important to consider the long - term cost. A more expensive magnet with a higher quality and longer lifespan might be a better investment in the long run than a cheaper magnet that needs to be replaced frequently.
Customer Support
When you're choosing a supplier for your 6x2mm disc magnets, it's important to consider the level of customer support they offer. At our supply, we have a team of experts who are ready to answer your questions and help you choose the right magnet for your project.
