Cup magnets are made from neodymium magnets, the world's strongest magnets. Neodymium cup magnets provide much stronger holding power than ceramic cup magnets.
This handy and useful neodymium cup magnet has a strong magnet embedded inside a Epoxy+Nickel+Cu coated steel cup to offer the maximum gripping power. The steel cup offers protection for the magnet and concentrates the magnetic force on the magnet surface.The magnetic cup has a countersunk center hole that is perfect for mounting with a flat head screw or bolt.
Neodymium Cup Magnets Size: 25.4 mm Diameter x 9 mm thick.
1" Diameter x 0.35" thick with 0.42" x 0.21" countersunk hole 82 degree.
Counter sink hole is to recess a #8 or #10 screw head.
Steel cup and magnets are Epoxy+Copper+Nickel Triple Layer Coated for maximum protection and durability.
3-layer coating (Nickel + Copper + Nickel and Epoxy + Copper + Nickel) vs. Epoxy single layer coating
Epoxy single layer coating is THE LEAST durable coating from our experience.
3-layer coating is much more durable than Epoxy single layer coating because Epoxy single layer coating is a thin layer of plastic and quicker to wear off, even a scratch can damage the coating easily.
More importantly, magnets with 3-layer coating have superior cracking and chipping resistance in comparison to magnets with Epoxy single layer coating. Customer beware of the magnets with the inferior Epoxy single layer coating.
Epoxy+Copper+Nickel 3-layer coating vs. Nickel+Copper+Nickel 3-layer coating
Epoxy + Copper + Nickel 3-layer coating has superior Corrosion Resistance and excellent adhesion to metal surface than Nickel + Copper + Nickel coating, this coating is ideal for bonding metal. Nickel+Copper+Nickel coating provides protection against moisture and oxygen but is prone to corrosion in salt and acidic conditions.
Neodymium cup magnets are widely used in industrial applications such as fastening, holding, hanging or retrieving objects, etc.
