12000GS Rust-Resistant Epoxy Magnet

This permanent magnet is made from metal and coated with a premium epoxy layer plus a three-stage nickel plating system (bright, protective, and bottom nickel) on its steel base. The plating guarantees excellent electrodeposition uniformity, high resistance to corrosion and scratching, and a clean, glossy, mirror-like appearance. Dimensions are subject to a ±1–3 cm manufacturing tolerance. All units pass rigorous in-factory inspection for size, surface quality, and magnetic flux — complying with ISO9001 quality management requirements. Designed for zero-maintenance operation: fully rust-resistant under normal indoor usage. Recommended for education, light-duty DIY, and office-based magnetic organisation tasks.
