A quote-ready custom magnet drawing should define the finished part, its magnetic orientation, and the conditions under which it must work. At minimum, include the material family and grade, final dimensions and critical tolerances, magnetization direction, coating, continuous and peak temperature, magnetic acceptance criteria, quantity, and inspection requirements. The most expensive ambiguities are usually an […]

Introduction When engineers develop a miniature magnetic assembly, they often need magnet samples quickly. At the early prototype stage, the final design may not be fully fixed, and the engineering team may simply need a small ring magnet that is close enough to test fit, magnetic response, sensor position, or assembly function. This is where […]

Introduction Countersunk neodymium magnets are widely used when a magnet needs to be mechanically fixed with a screw. They are common in furniture, access panels, display fixtures, enclosures, packaging, tool holders, signage, equipment covers, and custom magnetic assemblies. Compared with plain disc magnets, countersunk magnets are easier to mount securely because the screw head sits […]

Introduction SmCo cylinder magnets are widely used in applications where magnetic stability, high-temperature resistance, and long-term reliability are more important than simply choosing the strongest magnet available. Compared with NdFeB magnets, SmCo magnets usually provide lower maximum magnetic strength, but they offer excellent thermal stability, good corrosion resistance, and reliable performance in demanding environments. For […]

Introduction When engineers design miniature magnetic components, it is common to ask for the strongest possible NdFeB magnet grade. At first glance, the choice may seem simple: if N54 is stronger than N48, then N54 should be better. In real miniature designs, however, the answer is rarely that simple. For very small magnets, the final […]

Introduction NdFeB disc magnets are widely used in sensors, motors, magnetic couplings, positioning devices, encoders, holding systems, and compact mechanical assemblies. Most standard disc magnets are axially magnetized, meaning the north and south poles are located on the two flat faces of the magnet. However, some applications require a different magnetic field direction. In these […]
