D25mm magnets are commonly used in a wide range of applications, including door magnets, sensors, motors, electrical components, and structural fastening. If you need 25mm diameter ferrite magnets, please contact NST for samples or pricing.
In terms of specifications, D25mm round ferrite magnets are available in various thicknesses, including common options such as D25x2mm, D25x3mm, D25x4mm, D25x5mm, D25x8mm, etc. Additionally, for D25mm ferrite magnetic rings, our company commonly offers sizes such as D25xd8x6mm, D25xd15x12mm, D25xd12.5x3mm, D25xd16.5x9mm, and so on.
When selecting materials, you can choose between sintered ferrite, injection-molded ferrite, or rubber ferrite. Regardless of the material, they all offer stable magnetic properties, corrosion resistance, and resistance to demagnetization, making them ideal for cost-sensitive applications where magnetic performance requirements are not particularly stringent.
