Type: Ferrite Block Magnet Length: 25mm Width: 5mm Height: 5mm Grade: C8 / Y30H-1 Pull Strength: Approx. 450g Maximum Operating Temperature: 250°C This Ferrite Block 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 450g, this ferrite block magnet provides reliable holding performance for a wide range of industrial, commercial, educational, hobby, and DIY applications. 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 Excellent corrosion and rust resistance No protective coating required Suitable for indoor and outdoor use High temperature resistance up to 250°C Cost-effective permanent magnet solution Ideal for general industrial, commercial, educational, hobby and DIY applications Please Note: Pull strength figures are approximate and are measured under ideal conditions against a thick, clean mild steel surface with direct contact. Actual holding force will vary depending on the mounting surface, air gap, paint, coatings, and application.
