Neodymium Block Cube & Bar Magnets
Neodymium block magnets are the strongest commercially available rare earth magnets in rectangular or cube shapes. They are incredibly powerful relative to their size and have a wide range of applications. Neodymium block magnets are made from a rare earth alloy of neodymium, iron, and boron, which gives them exceptional magnetic properties. They are known for their high magnetic field strength, resistance to demagnetization, and low cost compared to other rare earth magnets. These magnets come in a variety of sizes, ranging from tiny 1/8 inch cubes to small 1/4 inch long bar and to large 6 inch blocks. Common sizes include 1/4 inch, 3/8 inch, 1/2 inch, 1 inch, 1.5 inches and 2 inches, They are available in different grades, such as N35, N42, N48, and N52, which indicate their magnetic strength. Neodymium block magnets are often plated with a protective coating, such as nickel-copper-nickel or zinc, to prevent corrosion and improve durability. This allows them to maintain their magnetic performance over time. Due to their incredible strength, neodymium block magnets have a wide range of applications. They are commonly used in electronics, industrial equipment, speakers, medical devices, arts and crafts, and various DIY projects. Their powerful magnetic fields make them useful as Scientific and Educational, audio speakers, fasteners, separation, holders, lifting and retrieving. Overall, neodymium block and bar magnets are an excellent choice for applications requiring a strong, compact, and reliable permanent magnet solution.
