Hey there! As a supplier of Alnico bar magnets, I often get asked about the common sizes available in the market. So, I thought I'd share some insights with you.
First off, let's talk a bit about Alnico bar magnets. Alnico is an alloy made up of aluminum (Al), nickel (Ni), and cobalt (Co), along with other elements like iron. These magnets are known for their high magnetic strength, good temperature stability, and resistance to corrosion. They're used in a wide range of applications, from electric motors and generators to sensors and loudspeakers.
Now, onto the sizes. The common sizes of Alnico bar magnets can vary quite a bit depending on the specific needs of different industries and applications. Here are some of the most frequently requested sizes:
Small - Sized Alnico Bar Magnets
Small - sized Alnico bar magnets are often used in precision instruments and delicate electronic devices. These magnets typically have a length ranging from 10mm to 50mm, a width of 2mm to 10mm, and a thickness of 1mm to 5mm. For example, a common small - sized Alnico bar magnet might be 20mm long, 5mm wide, and 2mm thick. These tiny magnets pack a punch and are great for applications where space is limited, like in some types of micro - sensors or small - scale electric actuators.
Medium - Sized Alnico Bar Magnets
Medium - sized Alnico bar magnets are more versatile and are used in a broader range of applications. The length of these magnets usually falls between 50mm and 150mm, with a width of 10mm to 30mm and a thickness of 5mm to 15mm. A typical medium - sized Alnico bar magnet could be 100mm long, 20mm wide, and 10mm thick. They're commonly found in electric motors for household appliances, small generators, and some types of magnetic separators.
Large - Sized Alnico Bar Magnets
Large - sized Alnico bar magnets are used in heavy - duty applications that require a strong magnetic field. These magnets can have a length of 150mm or more, a width of 30mm or greater, and a thickness of 15mm or more. For instance, in some industrial electric motors or large - scale generators, you might find Alnico bar magnets that are 200mm long, 50mm wide, and 20mm thick. These big magnets are capable of generating a powerful magnetic force, making them suitable for applications where high - torque or high - power output is needed.
It's important to note that these are just general guidelines, and we can also customize the size of Alnico bar magnets according to your specific requirements. Whether you need a magnet with a non - standard length, width, or thickness, we've got you covered.
In addition to the bar magnets, we also offer other types of Alnico magnets. If you're interested in Alnico Disc Magnet, they come in various diameters and thicknesses and are often used in applications where a flat, circular magnetic field is required. Alnico Rod Magnet are also available, which are great for applications where a long, cylindrical magnetic field is needed. And for applications that require a ring - shaped magnetic field, our Alnico Ring Magnet are a perfect choice.
When it comes to the magnetic properties of Alnico bar magnets, they have a relatively high remanence (Br), which means they can retain a strong magnetic field even after the external magnetic field is removed. They also have a high coercivity (Hc), which makes them resistant to demagnetization. However, compared to some other types of magnets like neodymium magnets, Alnico magnets have a lower energy product (BH)max. But this doesn't mean they're any less useful. In fact, their high temperature stability makes them a better choice in applications where the magnet will be exposed to high temperatures.
So, if you're in the market for Alnico bar magnets or any other type of Alnico magnets, don't hesitate to get in touch with us. We have a team of experts who can help you choose the right magnet for your application and ensure that you get the best quality product at a competitive price.
