The Ceramic Disc with Hole Magnet for General - Purpose Use is a versatile, cost-effective magnetic component designed to meet the everyday needs of consumers, small businesses, and light industrial applications. Made from ceramic ferrite—a composite of iron oxide, strontium, and barium—this disc-shaped magnet with a central hole offers reliable magnetic performance, durability, and affordability, making it ideal for a wide range of uses, from home organization to light manufacturing. Typically ranging in outer diameter from 15mm to 100mm, inner hole diameter from 3mm to 20mm, and thickness from 3mm to 15mm, it delivers moderate holding force (2kg to 30kg) that is strong enough for most general tasks while remaining easy to handle.

One of the primary advantages of the Ceramic Disc with Hole Magnet is its exceptional durability and resistance to harsh conditions. Unlike neodymium magnets, which require protective coatings to prevent rust, ceramic ferrite is naturally non-porous and impervious to moisture, saltwater, and most chemicals. This makes it perfect for outdoor or damp environments, such as garden tool storage (where the magnet can be mounted on a shed wall to hold metal tools like trowels or pruning shears) or bathroom organization (to attach metal toiletries holders to tile walls using magnetic strips). For example, a 50mm outer diameter, 10mm inner hole ceramic disc magnet can be bolted to a wooden garden shed wall, and its magnetic force holds a set of metal gardening tools securely, even in rainy or humid weather.

In home and office organization, this ceramic disc magnet is a practical tool for reducing clutter. A 25mm disc magnet with a 5mm hole can be used to attach a key holder to a kitchen wall: the magnet is bolted to the wall, and its magnetic force holds a set of metal keys, keeping them easily accessible but off the countertop. In an office, 30mm ceramic disc magnets can be used to secure whiteboard markers or small metal baskets to a magnetic board, organizing supplies and freeing up desk space. The hole in the magnet allows for easy mounting with screws or bolts, ensuring it stays securely in place even with frequent use.

Light industrial and commercial applications also benefit from the Ceramic Disc with Hole Magnet’s affordability and reliability. In small manufacturing facilities, 80mm disc magnets with 15mm holes can be used to hold lightweight metal components during assembly, such as small parts in a toy factory. The magnet’s moderate force ensures the parts stay in place during gluing or fastening, while its ceramic material resists damage from dust or minor impacts. In retail settings, these magnets can be used to attach small display shelves to metal walls, allowing store owners to showcase small products like jewelry or phone accessories without drilling holes in the wall.

Another key advantage is the magnet’s resistance to demagnetization. Ceramic ferrite magnets have a high coercivity (the ability to resist losing magnetic strength), meaning they retain their magnetism for decades with minimal degradation. This longevity makes them a cost-effective choice for long-term applications, such as in HVAC systems (where the magnet can be used to hold metal air filter covers in place) or home appliances (like refrigerators, where it secures small metal bins for food storage).

Whether used for home organization, outdoor storage, light manufacturing, or retail displays, the Ceramic Disc with Hole Magnet for General - Purpose Use combines versatility, durability, and affordability. Its ability to meet a wide range of everyday needs makes it a go-to magnetic solution for consumers and small businesses alike.
