OD 30mm x ID 20.5mm x 5mm Ring Magnet (Ferrite)

Type: Ferrite Ring Magnet
Outside Diameter: 30mm
Inside Diameter: 20.5mm
Height: 5mm
Grade: C8 / Y30H-1
Pull Strength: Approx. 800g
Maximum Operating Temperature: 250°C

This OD 30mm x ID 20.5mm x 5mm Ferrite Ring Magnet is manufactured from C8 / Y30H-1 ceramic ferrite, providing reliable magnetic performance with excellent corrosion resistance and outstanding temperature stability.

Ferrite magnets are naturally resistant to rust and corrosion, making them suitable for both indoor and outdoor applications without requiring protective coatings. They are an economical choice for many holding, positioning, educational, display, craft, and industrial applications where reliable magnetic performance, excellent corrosion resistance, and high temperature stability are more important than maximum magnetic strength.

With an approximate pull strength of 800g, this ferrite ring magnet provides reliable holding performance for a wide range of industrial, commercial, educational, hobby, and DIY applications. The central hole allows it to be mounted with a screw, bolt, or shaft.

Unlike neodymium magnets, ferrite magnets maintain their magnetic properties at much higher operating temperatures, with a recommended maximum operating temperature of 250°C, making them suitable for applications exposed to elevated heat.

Features

• Manufactured from C8 / Y30H-1 ferrite ceramic
