Gluing magnets

A magnet is nothing more than a piece of metal that attracts another piece of metal. It creates a magnetic field around itself, which generates forces that act on moving electric charges. Each magnet has two poles. north and south. Magnets attract metal elements made of iron, steel or nickel, but do not react with non-ferrous and precious metals.

Magnets can be made of a variety of materials. The most popular are ferrite magnets, which show high resistance to corrosion and high mechanical strength. Neodymium magnets are most commonly used in industry. Neodymium magnets are characterized by a much greater attraction force than ferrite magnets. This is due to the fact that the polarization direction of the neodymium magnets is defined already at the production stage.

How to connect magnets?

Due to the huge range of applications of magnets in many industries and industries, it is necessary to combine them with other materials. Various techniques are used to do this. Usually it is welding, but more and more often gluing. Bonding magnets with other materials using adhesives does not require much experience and can be done both in industrial and home conditions. Currently, magnet bonding is very often used in the assembly process of electric motors. However, in order to obtain a permanent connection, we must be sure that the glue used for this purpose is properly selected.

Magnet adhesive - which one to choose?

Magnets are often coated with galvanic coatings that exhibit anti-adhesive properties, so they are difficult to glue. This and many other factors should be taken into account when choosing the right preparation for bonding magnets to other materials. A good solution will be to use glue dedicated to magnets. We will then be sure that the glue will bond the surface of the magnet well with the place to which it is to be attached.

• Loctite 480 is a rubber-reinforced high performance instant adhesive. It guarantees higher flexibility, is resistant to tearing and impacts. It will work well in environments with increased humidity.
• A good solution for gluing magnets is also the use of metal glue, e.g. However, it will be necessary to properly prepare the surface before sticking the magnet. When bonding a magnet to metal, the metal surface must first be degreased using e.g. plastics-and-metals%2C-no-residue%2C-for-surface-preparation-before-bonding%2C-universal%2C-removes-most-lubricants%2C-oils/3526"> Loctite SF 7063 .
• We also suggest gluing magnets to metal with a two-component adhesive, e.g. Melkib MMA Power 10 is a high hardness methacrylate adhesive that creates very strong and durable joints. It is available in 50ml and 400ml cartridges, the set includes a mixing nozzle.
• To join magnets, Loctite AA 326 This product is cured between closely adhering surfaces and with Loctite 7649 activator. The adhesive will not cure until the two surfaces come together.
• Affixing magnets to wood can be more problematic than trying to attach to other surfaces. A lot will depend on the preparation of a given piece of wood and even the smallest unevenness is best sanded. A good quality cyanoacrylate adhesive such as Loctite 454 Henkel brands. Loctite 454 is a gel-type adhesive that works great on porous surfaces.
• The process of gluing magnets to various types of plastics is best carried out using epoxy or universal glue. A good choice here would be Loctite 401 - is a universal, low-viscosity adhesive for virtually all types of plastics.

The Melkib company has a wide range of products dedicated to connecting magnets with various materialsami and professional advisors will help you choose the right product.
