Neodymium Disc Magnet – 6mm x 2mm | Gold Coating

The Neodymium Disc Magnet – 6mm x 2mm | Gold Coating is a small rare earth permanent magnet measuring 6mm in diameter x 2mm thick. Manufactured from Neodymium Iron Boron (NdFeB) with a distinctive gold-coloured coating, this compact round magnet combines the high magnetic performance relative to size associated with neodymium with a decorative metallic finish.

Its miniature 6mm diameter and low-profile 2mm thickness make this gold-coated neodymium magnet suitable for compact product assemblies, craft and design projects, models, displays, lightweight closures, sensors, positioning applications, prototypes and custom OEM products. The gold finish can also make it useful where the magnet may remain visible as part of the finished product and a gold-coloured appearance is preferred over a conventional silver-coloured finish.

Also known as a gold neodymium disc magnet, gold-coated rare earth magnet, NdFeB disc magnet, small round neodymium magnet, miniature rare earth magnet or gold-plated-style magnet, this permanent magnetic component requires no electricity, batteries or charging.

6mm Diameter x 2mm Thick Disc Magnet

This neodymium disc magnet measures 6mm in diameter x 2mm thick.

Its diameter is three times its thickness, creating a compact, low-profile circular magnet that can be integrated into relatively small products and assemblies.

This geometry may be useful where:

• Installation space is limited
• A shallow circular recess is available
• A small magnetic closure is required
• The magnet needs to remain discreet
• Multiple magnets need to be incorporated into an assembly
• A visible gold-coloured magnetic component is preferred

The stated dimensions describe the physical size of the magnet and should not be interpreted as a pull-force or load rating.

Gold-Coated Neodymium Magnet

The magnet features a gold-coloured coating, giving it a distinctive metallic appearance compared with the silver finish commonly associated with many neodymium magnets.

The gold finish can be useful in applications where appearance is an important consideration, including:

• Decorative products
• Display pieces
• Craft projects
• Accessories
• Premium product assemblies
• Visible magnetic closures
• Custom designs

The coating also forms a surface layer over the underlying NdFeB magnetic material.

Care should be taken to avoid scratching, chipping or otherwise damaging the coating during installation and use.

The exact coating-layer construction and thickness have not been supplied and should not be assumed.

Neodymium Iron Boron Rare Earth Magnet

Neodymium Iron Boron is a high-performance rare earth permanent magnetic material.

NdFeB magnets are widely used where relatively high magnetic performance is required from compact dimensions, making them particularly useful in small product designs where available space is limited.

Potential functions include:

• Magnetic attraction
• Positioning
• Alignment
• Sensing
• Switching
• Closures
• Product integration

The specific neodymium grade has not been supplied for this magnet and should not be assumed.

Small Product Assemblies

The compact 6mm x 2mm dimensions make this disc magnet suitable for incorporation into appropriately designed small products.

Potential applications include:

• Boxes
• Cases
• Displays
• Models
• Accessories
• Equipment components
• Product housings
• Prototype devices
• Custom mechanisms

The magnet can be installed within a suitable recess or bonded to another component where appropriate.

Magnetic Closures

Small neodymium disc magnets are commonly incorporated into lightweight closure systems.

Potential applications include:

• Boxes
• Cases
• Packaging
• Displays
• Craft products
• Small access panels
• Decorative products

A magnetic closure can use either another magnet or a compatible ferromagnetic steel component as the mating surface.

Closure performance depends on the complete design, including:

• Magnet orientation
• Mating component
• Air gap
• Contact area
• Mechanical leverage
• Alignment

Where accidental opening could create a hazard, use appropriate mechanical retention in addition to magnetic attraction.

Craft and Design Applications

The combination of miniature dimensions and a gold-coloured finish can make this magnet useful for craft and design projects where both function and appearance are important.

Potential uses include:

• Handmade products
• Decorative closures
• Models
• Miniatures
• Displays
• Custom accessories
• Art projects
• Prototype designs

Because neodymium magnets are brittle, they should be securely retained and protected from impact within the finished product.

Sensors and Magnetic Switching

Compact neodymium disc magnets can be incorporated into sensor systems where the magnetic field configuration is compatible with the selected sensor.

Potential applications include:

• Position detection
• Proximity sensing
• Hall-effect sensors
• Reed switches
• Magnetic switching
• Instrumentation
• Small electronic assemblies

Sensor performance depends on factors including:

• Magnetisation direction
• Pole orientation
• Magnet-to-sensor distance
• Sensor sensitivity
• Installation geometry

The magnetisation direction has not been supplied and should be confirmed before designing a sensing system around this magnet.

Magnetisation Direction

Disc magnets can be manufactured with different magnetisation configurations.

A 6mm x 2mm neodymium disc magnet could potentially be:

• Axially magnetised through its 2mm thickness
• Diametrically magnetised across its 6mm diameter
• Multipole magnetised
• Manufactured with another specialised pole arrangement

The magnetisation direction and pole configuration have not been supplied and should not be assumed from the disc shape.

Confirm the magnetic orientation where pole location or field direction is important.

Magnetic Performance

The practical performance of this small neodymium magnet depends on factors including:

• Neodymium grade
• Magnetisation direction
• Pole configuration
• Magnetic circuit design
• Target material
• Target steel thickness
• Contact area
• Surface condition
• Air gaps
• Load direction

No specific pull force or magnetic flux density in Gauss has been supplied.

These values should not be inferred from the 6mm diameter x 2mm thickness alone.

Small Magnets and Air Gaps

Air gaps can have a particularly noticeable effect on miniature magnetic assemblies.

Even small amounts of separation may reduce magnetic attraction.

Potential sources of an air gap include:

• Paint
• Adhesive
• Plastic
• Fabric
• Paper
• Protective coatings
• Product housings
• Mechanical clearance

For maximum practical attraction, unnecessary separation between the magnet and magnetic target should generally be minimised.

Direct Pull vs Shear Force

Where the magnet is used against compatible steel, holding performance varies with load direction.

Direct pull occurs when the magnet is separated perpendicular to the target.

Shear loading occurs when the magnet is encouraged to slide parallel to the target.

Shear performance depends strongly on factors such as:

• Surface friction
• Surface condition
• Air gaps
• Installation orientation
• Mechanical leverage

Where holding performance is important, test the completed product in its actual orientation.

Target Steel Thickness

The target steel itself can influence magnetic performance.

Important factors include:

• Steel composition
• Steel thickness
• Target dimensions
• Surface condition
• Contact area
• Magnetic saturation

Very thin steel may not provide the same magnetic response as a suitable thicker ferromagnetic target.

For performance-critical applications, test the magnet against the actual target material.

Bonding a Gold-Coated Neodymium Magnet

Adhesive bonding can be used to integrate this magnet into a suitable product or housing.

Before bonding:

• Confirm the required magnetic orientation
• Confirm polarity where multiple magnets are involved
• Clean the bonding surfaces
• Remove grease, dust and contamination
• Select an adhesive compatible with the gold-coated surface and mating material
• Provide appropriate dimensional clearance
• Avoid force-fitting
• Allow the adhesive to cure according to its instructions

The exact gold coating construction has not been supplied, so adhesive compatibility should be confirmed for the intended application.

Protect the Gold Coating

The coating should be protected from unnecessary scratching, abrasion and impact.

Damage to the surface finish can affect:

• Appearance
• Surface integrity
• Long-term protection of the underlying magnetic material

When installing the magnet, avoid scraping it against hard surfaces or gripping it with tools that could damage the coating.

Avoid Force-Fitting

Neodymium Iron Boron is hard but brittle.

Do not force this magnet into an undersized recess.

Excessive pressure can cause:

• Chipping
• Cracking
• Fracturing
• Damage to the gold coating

Provide suitable dimensional clearance and use an appropriate retention method.

Do Not Machine Neodymium Magnets

Finished neodymium magnets should not be modified using conventional workshop methods.

Avoid:

• Drilling
• Cutting
• Grinding
• Crushing
• Machining

These processes can damage both the brittle NdFeB material and its protective coating.

If another diameter, thickness or shape is required, select a magnet manufactured to the required dimensions.

Compatible Target Materials

Neodymium magnets attract suitable ferromagnetic materials, including:

• Mild steel
• Iron
• Magnetic steel
• Compatible ferromagnetic components

They will not effectively attract inherently non-magnetic materials such as:

• Aluminium
• Copper
• Brass
• Plastic
• Timber
• Glass

Many stainless steel grades can also be weakly magnetic or non-magnetic and should be tested before relying on magnetic attachment.

Neodymium vs Ferrite Disc Magnets

Neodymium and ferrite disc magnets provide different characteristics.

Neodymium disc magnets generally provide:

• Higher magnetic performance relative to size
• Strong magnetic properties from compact dimensions
• Advantages in miniature product designs
• Suitability where installation space is limited

Ferrite disc magnets generally provide:

• Lower cost
• Good natural corrosion resistance
• Good resistance to demagnetisation
• Suitability where larger dimensions are acceptable

Neodymium is therefore commonly selected where higher magnetic performance from a small, lightweight magnetic component is required.

Permanent Magnetic Operation

This gold-coated neodymium disc is a permanent magnet.

It requires:

• No electricity
• No batteries
• No charging
• No external power supply

Its magnetic field remains continuously active during normal use.

Safety and Handling

Despite its small size, a neodymium magnet should be handled carefully.

Small magnets can attract each other or ferromagnetic objects suddenly, potentially causing:

• Pinched skin
• Magnet collisions
• Chipping
• Cracking
• Fragmentation
• Damage to the coating

Serious Ingestion Hazard

Small neodymium magnets present a serious ingestion hazard.

If more than one magnet is swallowed, or a magnet is swallowed together with another magnetic or metallic object, they can attract through internal tissue and cause severe injury.

Keep this magnet securely away from babies and children.

If incorporated into another product, the magnet should be securely retained so it cannot become loose or accessible during normal use or reasonably foreseeable misuse.

Seek urgent medical attention if magnet ingestion is suspected.

Permanent magnets should also be kept an appropriate distance from pacemakers, implanted medical devices, magnetic storage media, magnetic cards and sensitive electronic equipment.

Please Note

This product is a Gold-Coated Neodymium Disc Magnet measuring 6mm in diameter x 2mm thick, manufactured from Neodymium Iron Boron (NdFeB) rare earth magnetic material.

The magnet has a gold-coloured coating, but the exact coating-layer construction and thickness have not been supplied.

No specific neodymium grade, pull force, Gauss rating, magnetisation direction, pole configuration, dimensional tolerance or maximum operating temperature has been supplied and these specifications should not be assumed.

Actual magnetic performance depends on the neodymium grade, magnetisation configuration, magnetic circuit, target steel composition and thickness, available contact area, surface condition, air gaps and load direction.

Neodymium is a hard and brittle magnetic material. Avoid impact, force-fitting, drilling, cutting, grinding or machining, and protect the gold coating from unnecessary scratching and abrasion.

The stated 6mm diameter x 2mm thickness describes the physical size of the magnet and does not represent its pull force, holding capacity or safe working load.

This magnet is not certified lifting equipment and should not be used for overhead or safety-critical lifting.
