Screw-on neodymium magnets round, square, with one or two holes

Rare Earth Countersunk Holding Magnets

Countersunk Hole Magnets are very popular amongst tradespeople and fabricators. Frequently used as magnetic closures for cabinets, gates and door latches and any other hidden magnetic closure mechanism. The hole allows the Neodymium magnet to be secured on any surface with a screw or bolt. Rare Earth magnets are brittle and can break easily if mishandled; countersunk magnets provide a convenient means of securing the magnet without causing damage. Countersunk magnets are commonly used for shop-fitting, shelving and lighting fixtures, window and screen displays as well as to hold and hang signage.

Countersunk Magnets, also known as Round Base, Round Cup, Cup or RB magnets, are powerful mounting magnets, built with neodymium magnets in a steel cup with a 90° countersunk hole on the working surface to accommodate a standard flat-head screw. The screw head sits flush or slightly below the surface when affixed to your product.

• The magnetic holding force is focused on the working surface and is significantly stronger than an individual magnet. The non-working surface is very little or no magnetic force.
• Constructed with N42 Neodymium magnets encased in a steel cup, plated with a triple-layer of Nickel-Copper-Nickel (Ni-Cu-Ni) for maximum protection against corrosion & oxidation.
• Neodymium cup magnets are used for any application where high-magnetic strength is required. They are ideal for lifting, holding & positioning, and mounting applications for indicators, lights, lamps, antennas, inspection equipment, furniture repair, gate latches, closing mechanisms, machinery, vehicles & more.

We carry a large inventory of Neodymium Countersunk Magnets, not all of which are shown on this website. Contact us today or send us a by eMail: info(at)magnosphere.co.uk. Available 24/7 x 365 and we are also there for you on public holidays! Or just give us a call.

Rare Earth Countersunk Magnets Info:

The approximate pull info listed for Neodymium Cup Magnets is for reference only. These values are measured under the test conditions where the magnet is attached to a flat, ground 1/2" thick mild steel plate. Coatings, rust, rough surfaces, and certain other environmental conditions can significantly reduce the pull force. Please be sure to test the pull in your actual application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure.

Our super strong neodymium disc magnets have wide variety grade N35, N38, N40, N42, N45, N50 and N52. The strong neodymium discs have Nicuni, Zinc and Epoxy coatings, sometimes the disk magnets with a countersunk hole that drilled in the middle to attach it to nonmetallic materials, such as wood or plastic plant. These round magnets can allow the screw’s head to reside below, or maybe with the face of the magnet to ensure it doesn’t interfere with the magnet’s performance. Neodymium disc and round magnets are widely used for motor, sensor and holding applications.

How to Safely Seperate Your Magnosphere Magnets?

CORRECT

1. Slide one magnet off the top of the stack.
2. Once off thestack,carefully start lifting the magnet.
3. Lift the magnet to free it from the stack.

INCORRECT

1. DO NOT attempt to pull, lift, or pry amagnet from the stack before sliding it to the side.
2. DO NOT throw away the white storage spacers.
3. DO NOT allow the magnets to snap to each other or any magnetic surface. doing so may cause magnets to break!

What are Rare Earth Magnets?

Rare earth magnets, also known as neodymium magnets or samarium cobalt magnets are magnets made from alloys of rare earth elements.  They are currently the strongest type of permanent magnets made, and produce significantly stronger magnetic fields than other types such as ceramic or alnico magnets.  Rare earth magnets have replaced alnico and ferrite magnets in many applications, including head actuators for computer hard disks, magnetic resonance imaging (MRI),loudspeakers and headphones, several types of motors, and more.

Neodymium (Rare Earth) Magnets: the strongest magnets in the world

Magnosphere offers best priced Neodymium magnets globally. Please inquire for custom Neodymium magnets or magnetic assembly. Neodymium is the strongest available magnet alloy at up to 52MGOe. The use of Neodymium results in smaller, more cost-effective magnet solutions replacing older materials like Alnico and Ceramic in many applications. Magnosphere.can help optimize performance and cost with Neo magnets in grades from 33 to 52MGOe and operating temperatures up to 230°C/446°F. (NdFeB) Neodymium, a rare earth magnet, is made up of Neodymium Iron and Boron and is moderate in price. A neodymium iron boron magnet is usually plated or coated (Examples: Nickel Plated, Epoxy Coated, Parylene Coated). Neodymium permanent magnets usually offer the best value when comparing price and performance. Stock Neodymium magnets are available in large quantities and dimensions.

Rare Earth Neodymium NdFeB

We provide a range of high magnetic strength Rare Earth Neodymium magnets including Disc magnets, Deep Pot magnets, Shallow Pot Neodymium and Round flat neodymium magnets,

• Neodymium NdFeB magnets are, size for size, the strongest type of any magnet material that is commercially available.
• Neodymium NdFeB magnets are often the ideal first choice for many applications because they offer a maximum performance from the smallest magnet volume.
• Neodymium NdFeB should always be coated to guard against the risk of corrosion – NiCuNi, Zinc, NiCuEpoxy and Gold are popular finishes.

Our Magnet-Shop carries a great variety of these powerful magnets to fit many different applications and they are in stock for immediate delivery!

Neodymium NdFeB magnets and their application!

At Magnosphere.co.uk, we sell custom Neodymium NdFeB magnets and custom magnetic assemblies so we can help you find the best fit for your project. Some of the common applications of the rare earth magnets are:

• Motors and Generators
• Meters
• Automotive (clamps, sensors)
• Aerospace
• Separation (rods, grids, etc) – 10-12kG (22-26lbs) systems
• High performance magnetic clamps and pot magnets
• They are used in computer hard drives.
• Rare earth magnets also find their utility in high-end speakers.

Based on the applications and properties earth magnets are of two types:

• Neodymium Magnet
• Samarium-Cobalt Magnet

Process of Making Rare Earth Magnets

• The rare earth magnets are made by using different process involving various stages. The popular stages of the production of rare earth magnets are:
• The first stage is the manufacture of rare earth element alloys.
• The metal alloy is then finely powdered.
• The next step involved is pressing of powder either isostatically or pressing through die process.
• The particles so pressed are oriented.
• Sintering of the element is done accordingly.
• The shapes are then sliced into desired shapes and sizes.
• The coating is done thereafter.
