22-30daysNeodymium magnet is the strongest and permanent magnet available today. It is easily formed into various shape and size, and belong to one of the most widely used magnetic materials. Low weight loss product, Low-temperature coefficient product, low deviation angle product, and radial oriented ring magnet are our featured products.
Grade of NdfeB Magnet
If your application is at room temperature only,the N series is the best choice,with a max operating temperature 80 degrees Celsius. Generally speaking,the N35 grade is relatively cost-effective and also have strong magnetic force. But which grade to choose depends on your pursuit of magnetic force or say application.
The higher the temperature of resistance of the magnet,the more expensive it is.For example,N35 grade and N35M grade have the same magnetic force,but the max operating temp. of N35M is 100 degrees Celsuis，N35 is only degrees Celsuis.
