CMS Magnetics Powerful Bar Magnets Neodymium Grade N45 3 x 1 2 x 1 4 4 Pack Super Strong Rectangular Magnets Cabinets Schools Crafts Magnets Door Magnets

This powerful heavy duty neodymium bar magnet measures 3" in length 1/2" in width and 1/4" in thickness and is made of a grade n45 neodymium iron and boron magnetic alloy blend. This bar magnet blend is patent licensed and made under the iso 9001 quality control systems and are plated in a nickel-copper-nickel triple layer coating for a shiny corrosion resistant finish. This magnet is great for holding purposes such as holding objects to magnetic surfaces. Moreover this magnet is versatile and robust applications range from industrial use to personal projects. Material: sintered ndfeb. Grade n45gauss rating: 13 500 gausspulling force: 33 lbspole orientation: magnetized through the thickness the poles are on the long 3" x 1/2" surfaces. Coating: ni+cu+ni 3 layer coating the best available. Tolerance: the tolerances of all the dimensions are +/-0. 002in with coating. Neodymium magnets are just pure raw power & are extremely versatile because of their strength and can be used in a wide variety of applications ranging from holding things onto your fridge to the most demanding industrial applications. General description these ultra strong bar magnets are a supermagnet & are made made for holding stuff & that is what they do they do best. These are not the magnets you played with as children 10-20 times the force of those old time magnets. Never experienced powerful neodymium 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. The magnetic strength will last forever under normal use.
