Grade C8 Ceramic Ring Magnet by Burnur 60mm OD x 24mm ID 2 Pack

Description

Product Overview

Burnur’s Grade C8 ceramic ring magnets are engineered from high‑performance ferrite material, delivering a reliable 8 lb (approximately 3.6 kg) holding force across the full 10 mm thickness. Each magnet measures 60 mm (2.36 in) in outer diameter, 24 mm (0.94 in) in inner diameter, and 10 mm (0.39 in) in thickness, providing a substantial magnetic field while maintaining a compact footprint. The magnets are magnetized through the thickness, with north and south poles located on the flat faces, allowing flexible placement on a variety of surfaces. The C8 grade indicates a high intrinsic coercivity of about 3,850 Oe, ensuring the magnets retain their strength even under demanding conditions. Manufactured under ISO 9001 quality‑controlled processes, each unit meets strict tolerances for dimension, magnetization, and surface finish, guaranteeing consistency across the 2‑piece pack.

Usage

These versatile ring magnets excel in both industrial and hobbyist environments. In manufacturing, they secure metal components on assembly lines, hold tooling in place, and serve as magnetic bases for CNC machines. For DIY enthusiasts, they are perfect for creating magnetic closures on cabinets, custom magnetic tool holders, and interactive art installations. Audio engineers appreciate the strong, stable magnetic field for speaker cone alignment and driver testing, while educators use them in physics labs to demonstrate magnetic flux, field lines, and force interactions. The magnets also find application in magnetic therapy devices, where a consistent 8 lb pull can be harnessed for therapeutic massage tools. Their corrosion‑resistant ferrite coating makes them suitable for outdoor experiments, garden tool organization, and marine‑related projects where moisture exposure is a concern.

FAQ

What is the maximum temperature these magnets can withstand?

Burnur C8 ceramic ring magnets are rated for continuous operation up to 250 °C (482 °F). Exceeding this temperature may reduce magnetic performance, so it is recommended to keep the magnets within the specified range for optimal longevity.

Can the magnets be used on non‑metallic surfaces?

Because the magnetic field is strongest at the flat faces, the magnets will attract ferromagnetic materials such as steel, iron, and certain alloys. They will not adhere directly to non‑magnetic surfaces like wood, plastic, or glass, but can be used with an intermediary metal plate or adhesive backing to expand their applicability.

How do I safely handle and store these magnets?

Handle the magnets with care to avoid pinching fingers between the inner and outer rings. Store them in a non‑magnetic container, away from electronic devices, credit cards, and other sensitive equipment. Keep them separated from other magnets to prevent sudden attraction that could cause damage.

Are the magnets suitable for use in scientific experiments?

Yes, their stable magnetic field and known holding force make them ideal for laboratory demonstrations of magnetic flux, field mapping, and force calculations. The precise dimensions also allow for reproducible setups in physics curricula and research projects.

What is the warranty coverage for these magnets?

Burnur provides a one‑year limited warranty covering any material or manufacturing defects that affect magnetic performance. If a magnet fails to meet the advertised holding force within the warranty period, contact our support team for a replacement or refund.
