Waterproof Neodymium Magnets with plastic cover and sewing in PVC

Waterproof neodymium magnets: rustproof & with scratch protection

These Neodymium disc magnets produce an astonishing pull. Every magnet is fully coated with PTFE which makes them completely waterproof and ideal for outdoor use or applications where the magnet may come into direct contact with water. What's more, because of their resistance to demagnetisation they are ideal for creating a shock-absorbing or damping effect when used to repel other magnets.

The neodymium magnets entirely coated by a layer of rubber or plastic, or even shrink-wrapped into a plastic cover, which provides the following advantages:

• Waterproof: These magnets are rustproof and can be used outdoors and in wet surroundings or even washed if necessary
• Friction (only for rubberised magnets): The rubber layer significantly increases the magnetic force in shear direction
• Scratch protection: Delicate surfaces, such as whiteboards or magnetic glass boards, are well protected

Can be used for:

These magnets have enough strength to be used as fridge magnet, sign, note or picture holder, hardware tools hanger, shower door, work or office, scientific purposes, artwork, projects, aquariums, jewelry and handcraft DIY material.

• Fridge magnet
• Scientific Experiment
• DIY items, craft, hobbies
• Hanging tools, glasses, signs
• Security windows or display curtains

Due to the rubber or plastic coating, the maximum adhesive force of these magnets is slightly lower, however, compared to similar-sized neodymium magnets without coating.

Neodymium block magnets with plastic coating

The strong neodymium magnets are encased in plastic, making them perfect for outdoor use. The polypropylene jacket protects the magnet from oxidation on the one hand, and scratches the surfaces to which the magnet is attached too.

Round neodymium disc magnets with plastic coating

The strong neodymium magnets are encased in plastic, making them perfect for outdoor use. The polypropylene jacket protects the magnet from oxidation on the one hand, and scratches the surfaces to which the magnet is attached too.

Due to the robust coating, these magnets have the following advantages:

• The use of the magnets in water or humid environments is possible without any problems, since the PP coating completely encloses the neodymium magnet.
• Sensitive surfaces are protected by the plastic coating. This means that these magnets can be used on whiteboards or magnetic glass boards, for example, without leaving any scratches.
• The cast-in magnet is nickel-plated, has a high magnetization quality and has a maximum operating temperature of 80°C.

Sew-in waterproof neodymium magnet in square PVC case

This magnet consists of a strong disc magnet, which is welded into a solid plastic foil. The magnet is waterproof and rustproof thanks to the cover. This makes it ideal for use in damp environments or for sewing into clothing. Thanks to the plastic film, the magnet can also be washed without being damaged.

Waterproof rubberized neodymium round cylinder magnets

These neodymium magnets have a rubber coating and can be used permanently outdoors or in water. Our plastic-coated neodymium magnets are provided with robust rubber or plastic. The coating is corrosion-resistant, which means that the magnets can be used wonderfully as permanent magnets outdoors. Moist applications or even use under water are therefore possible.

Our coating not only keeps the magnet rust-free, but also offers scratch protection for sensitive surfaces and the magnet itself.

• Rust resistance even in wet environment
• Protection of sensitive surfaces such as whiteboards and magnetic glass boards from unwanted scratches

Magnets encased in stainless steel housing

• Structural: The whole magnet surface is wrapped with stainless steel, and the thickness of the stainless steel on the working surface is 0.6mm. The welded stainless steel jacket protects the magnet while reducing the loss of magnetic force.
• Performance: Put the product in water for 3-5 seconds, and no bubbling should form on the surface of the product.
• Use: Stainless steel has a good anti-rust effect on the magnet, so the magnet can be used in harsh environments with high humidity or corrosion without being damaged.

Characteristics and applications of the main coatings of magnets.

There are different types of coating for magnets, each with its own characteristics that are best suited to the environment in which the magnet is to operate.

Zinc coating:

This finish is suitable when the working temperature is reduced, indicatively below 130 °, has a low cost compared to other coatings and protects the magnet from corrosion in open air. It has a thickness of about 5 micrometers, a dull gray or bluish color and is less resistant than the NiCuNi coating.

NiCuNi coating:

It appears to be the type of coating most used due to its low cost and the wide range of compatible fields of application. It is a coating consisting of 3 layers (Nickel-Copper-Nickel), with a thickness of about 12 micrometers and which can be used in working environments with temperatures up to 230 ° C. It is generally of a bright metal gray color but there are also versions with black nickel or other colors where visual appearance needs require it.

Epoxy Coating:

A solution that provides excellent resistance to corrosion, especially in humid and brackish environments. It has a limited impact resistance so you must pay close attention to avoid oxidation, the maximum working temperature is about 150 ° C and has a thickness of about 12 micrometers.

Gold coating:

It is a very thin layer applied over the traditional NiCuNi for applications generally in the medical field, or decorative such as jewelry, because it is suitable for being in contact with the human body. The overall thickness is about 12 micrometers but since the gold is about 0.05 it is easily subject to wear. The maximum working temperature is not higher than 200 ° C.

Parylene coating:

It can be used in work environments with a maximum temperature of 150 ° C, suitable for use in the medical field because it is suitable for contact with the human body.

PTFE (Teflon) coating:

It is characterized by a high resistance to shocks and abrasion, in fact it makes the magnet waterproof; the maximum working temperature is about 250 ° C and the thickness is between 13 and 25 micrometers. Visually it is dark gray.

Rubber coating:

One of the main characteristics of this type of coating is the slip resistance it provides to the magnet or to the magnetic bases thus increasing the attraction to the metal surface. In addition to this, it offers the magnet excellent protection against shocks and corrosion. The maximum operating temperature is 80-100 ° C.

Plastic coating:

As with the PTFE and rubber coatings, this coating gives the magnet a high resistance to shocks and corrosion, the maximum working temperature will be linked to the type of plastic used.

Titanium Nitrate Coating:

It is characterized by strong adhesion to the magnet and use in environments with very high temperatures, obviously compatibly with the use of NdFeB magnets at high temperatures. Often employed in the medical and food sector being approved by the FDA; it does not easily lose its brilliance so it is often used for decorative applications.

Decorative coverings:

Copper, chrome and silver coatings are mostly used for their decorative characteristics, have thicknesses between 10 and 15 micrometers and have different degrees of abrasion resistance. Due to its electrical conductivity, the silver coating is often used in electronic parts or connectors

Buy Neodymium Magnets online

Neodymium Iron Boron (“Neo”, NdFeB or Neodymium) Magnets are made from an alloy containing, amongst others, the elements Neodymium, Iron and Boron (NdFeB). The NdFeB magnets are the strongest type of magnet commercially available and are manufactured in a wide range of shapes, sizes and grades. We offer 53 grades of licensed standard corrosion resistance Neodymium Iron Boron and now an additional 72 grades of improved corrosion resistance Neodymium Iron Boron, each type with 30 types of coating finish for each grade (125 grades in total with 34 finishes – 4250 combinations).

The NdFeB magnets are anisotropic sintered magnets – the alloy is jet milled to a fine powder and is then compacted in the presence of a magnetic field to give it a preferred direction of magnetisation. The NdFeB magnets are then sintered to fuse the powder together before final machining and magnetising produces the completed super strength Neodymium magnet.

The Neodymium magnets are also known as Neo magnets, Neodymium Iron Boron magnets, Neodymium-Iron-Boron magnets, Neodymium Magnets, NdBFe magnets, NdFeB magnets, NIB magnets, Super Strength magnets and Rare Earth magnets (please note that SmCo is also called a Rare Earth magnet). NdFeB is called a Rare Earth magnet because the Neodymium is a Rare Earth element, having a value of 60 on the Periodic Table. For note, there is nothing rare about Rare Earth magnets – the required elements are readily available and the NdFeB magnets are produced in several hundreds of tonnes each year.

The Neodymium Iron Boron magnets (NdFeB magnets) were developed just over 25 years ago and were first commercially available in 1984. Neodymium magnets were initially developed for voice coil motors in computer hard disk drives and this market still accounts for over 50 percent of all Neodymium magnets produced. Other applications include high performance motors, brushless DC motors, generators, magnetic separation, magnetic resonance imaging, sensors and loudspeakers. They are becoming increasingly popular across a wide range of novelty products such as fridge magnets and all kinds of magnetically attachable gadgets for retail markets.

The NdFeB (NIB) magnets, in disc and ring forms, are usually axially magnetised (the round ends are the magnet poles). Diametrically magnetised discs and rings can be produced upon request (looking at the circular end face, the magnetism runs from the 12 o’clock position to the 6 o’clock position in diametrically magnetised magnets). Likewise, the rectangular blocks can be specially produced to be magnetised in any of the three axes (the magnets cannot be re-magnetised in another axis due to the method of production – the sintered NdFeB is anisotropic). Arcs, trapezoids and other shapes can generally also be produced. Bespoke Directions of Magnetisation within the magnet shape may also be possible (subject to confirmation) e.g. for Halbach Array assemblies.
