This allows them to stack face-to-face perfectly, like a roll of coins.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I solder or weld these magnets to my project?\u003c\/strong\u003e\u003cbr\u003e\nA: No. Extreme heat (generally anything above 80°C) will permanently destroy the magnetic properties of a neodymium magnet. The most reliable attachment methods are press-fitting into perfectly sized holes, or using strong adhesives like two-part epoxy, cyanoacrylate (superglue), or double-sided VHB tape.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I drill a hole through a 15mm disc to screw it down?\u003c\/strong\u003e\u003cbr\u003e\nA: No. Neodymium magnets are manufactured via a powder metallurgy process, making them structurally brittle. Attempting to drill them will cause them to chip or shatter, and the heat generated by the friction can destroy their magnetism. If you need a screw hole, you must purchase a countersunk ring magnet specifically designed for that purpose.\u003c\/p\u003e\n\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e15mm Neodymium Magnet Disc (Thickness and quantity as selected)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORTED","offers":[{"title":"15X1.5 mm","offer_id":49517338231022,"sku":"MAG-02643","price":49.0,"currency_code":"INR","in_stock":true},{"title":"15X3 mm","offer_id":49517338263790,"sku":"MAG-02644","price":59.0,"currency_code":"INR","in_stock":false},{"title":"15X5 mm","offer_id":49517338296558,"sku":"MAG-02645","price":88.5,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/products\/neodimium.png?v=1608188436","url":"https:\/\/www.tomsonelectronics.com\/products\/15mm-neodymium-disc-magnet-multiple-thicknesses","provider":"Tomson Electronics ","version":"1.0","type":"link"}
