Neodymium Bar magnets are unique because of their extreme resistance to demagnetization and will only lose their magnetism if they're heated above 176 degrees fahrenheit. Technical magnets each of these bar magnets provides 16 pounds of holding power maximum working temperature 176 f (80 c)material: sintered ndfeb neodymium rating: 13 500 gauss pulling force pole orientation: axially magnetized the poles are on the ⅛ th thickness coating: ni+cu+ni 3 layer plated tolerance: all the dimensions are +/-0. 002in with coating these are not the Bar magnets you played with as children 10-20 times the force of those old time Bar magnets. Never experienced powerful neodymium bar magnets? now is the time! our rare earth magnets have a high saturation magnetization & tetragonal crystalline structure ensuring top physical pulling force & maximum energy product. These magnets hold very well against steel surfaces with direct touch and direct pull. The magnetic strength will last forever under normal use. Many uses & users cms magnetics’ neodymium bar magnets are used by school teachers machinists magicians engineering and manufacturing students hobbyists inventors technicians diyers mars rovers (yup up there) craft magnets uses hobbies therapy storage experiments science fairs magnetic bars labs garages schools offices & refrigerator magnets the right magnet for the right project cms magnetics is an established supplier of premium quality bar magnets that are used in some of the most demanding and critical applications such as aviation automation and manufacturing systems that help shape the world around you. Because we strive to only supply the highest quality magnets our magnets are all produced in state of the art facilities that ensure a high standard of both quality and performance are met. In addition to neodymium bar magnets which are renowned for their strength and versatility we also carry many different kinds of bar magnets that are all suited for different needs. From ultra high temperature resistant samarium-cobalt magnets to cost-effective and ubiquitous ceramic magnets cms magnetics is a trusted and reliable supplier of ultra high performance magnets in an assortment of all shapes and sizes. Additional information neodymium magnets come in all sorts of sizes strengths and magnet grades are used to identify the strength of a magnet. Grades range from n35 the cheapest and weakest to n52 for top power our magnets have a shiny strong triple layer coating that consists of a base layer of nickel a middle layer of copper and an exterior layer of nickel for physical strength & corrosion resistance.
