Featuring a corrosion-resistant triple-layer Ni-Cu-Ni coating, these magnets combine industrial strength with sleek design, perfect for professional, creative, and everyday applications. ## Description FINDMAG Super Strong Neodymium Disc Magnets with Double-sided Adhesive - 1.18"D x 1/8"H (4 Pack) Rare earth magnets are the strongest type of permanent magnet currently made. They are amazingly powerful for their size and have innumerable uses. These disc magnets are 1.18 inch (30 mm) diameter and 0.12 inch (3mm) thick. They are magnetized through the thickness. They are composed of neodymium iron boron magnetic material and are plated in nickel-copper-nickel for a shiny corrosion resistant finish. Maximum working temperature is 176 F (80 C). These 30 mm diameter Neodymium disc magnets produce an astonishing pull of 17lb and every magnet has a triple coating of nickel, copper and nickel again to prevent against corrosion. Our Neodymium magnets are commonly used in creative applications such as models and theatre design, furniture making, exhibition stands and packaging. They also have many uses in engineering and manufacturing where compact size and maximum strength are required. 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. Holding Force detection method: We use the automatic machinery in pull off speed 80 mm/min to test products by attracting on an 10 mm thick steel plate. ## Features - ✅【STRONGER THAN THE COMPETITION】 - Made from the world's strongest magnetic element, our pure neodymium disc magnets are incredibly powerful.
