Product Description
Neodymium Adhesive Backed MagnetsNdFeB Adhesive Backed MagnetsNdFeB magnets can be supplied with a high quality 3M adhesive backing. Simply peel away the protective cover from the adhesive and press in place to adhere.There is a practical size limit to how big the adhesive backed magnets can be. This is because bigger magnets provide magnetic pull forces which will exceed the forces given by the adhesive to stick the magnets in place – the result would be that the force required to take the magnet away from another magnet or ferromagnetic material will exceed the adhesive strength and the adhesive strip will fail and rip off. This is why adhesive backed magnets are small because it keeps the magnetic pull forces to a low enough value.In applications such as making folders and books with closure magnets, the magnets may be stuck on to the material on the folder or book cover and then the material they are stuck onto is folded over (effectively hiding the magnets from view) such that the magnets clamp together but with the adhesive sides facing (albeit with the adhesive layers plus material layers in between the magnets). This design hides the magnets, allows the magnets to work (perhaps with a lesser clamping force because the magnets are further apart) and clamping and prevents damage to the adhesive backing strip.Within reason, we can produce the NdFeB adhesive backed disc magnets in different sizes, different grades (strengths and temperature ratings), and different coatings/finishes as part of our custom magnet (made-to-order) service. We may be able to produce adhesive backed rectangular NdFeB blocks as well.Adhesive strong magnet is powerful Neodymium magnet with high quality 3M adhesive backing and a new, easy-pull tab. The neodymium magnet is Ni-Cu-Ni plated to protect them against corrosion and conventionally magnetized through the thickness.Usually, the magnets exist in two versions per size – the A version has a North Pole face visible; the B version has a South Pole face visible (so the A and B versions will stick to each other). South pole or North pole of magnet can be marked with a red dot on the face for easy identification. Another solution is a magnet will attract to a ferromagnetic (e.g. mild steel) material, it achieves perfect alignment with magnet-to-magnet applications, but more economical.The most regular adhesive is 3M 467 adhesive for this product, but if you do require any other adhesive like foam adhesive for your application, this will be also available. Also, we supply different packaging ways for this product.Adhesive strong magnet is available in small DIY packs and also in industrial bulk packs for the printing and display industries. They are ideal for invitation cards, envelopes, folders, trinket boxes, jewelry boxes, musical boxes, fridge magnets etc. Simply peel off back on each mating magnet and stick in desired area and you have a closed card, envelope, folder etc.Buyer’s GuideIn order to quote you the best price, please provide us the following informations.ShapeBlock/Rectangle/SquareDisc/Round/CylinderRing/CountersunkDimensionL (?) x W(? ) xT(?)D(?) x T(?)OD(?) x ID(?) x T(?)For other shapes,please tell more in details or drawing would be much appreciated.CoatingZn,Nickel,Ni-Cu-Ni,Epoxy,Au,Silver or other ?Working TemperatureNormal or High temperature ?Working Temperature Grade  Max.
