LARGE HIGH POWER MAGNETS CAN KILL!! BUYER ASSUMES ALL RESPONSIBILITY!! KEEP AWAY FROM CHILDREN AND PETS! THESE ARE GENUINE N48H (H-CLASS) NEODYMIUM MAGNETS! Not to be confused with the other Rare Earth magnets sold online. H-CLASS MAGNETS HAVE A MAXIUM OPERATING TEMPERATURE FAR HIGHER THAN STANDARD CLASS NEODYMIUM MAGNETS! ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- HOW MUCH HOTTER CAN THEY GET BEFORE THEY DIE? MAXIMUM OPERATING TEMPERATURE OF MAGNET TYPE: - STANDARD NEODYMIUM N48: 80 C - H-CLASS NEODYMIUM N48H : 140 C Standard neodymium magnets (N42, N45, N48, N50) have a maximum operating temperature of 80 Celsius!!! IF THEY GET HOTTER THAN 80 C. THEY BEGIN TO..... RAPIDLY AND PERMANENTLY LOSE THEIR MAGNETIC STRENGTH!!!!!! A magnet that isn't magnetic is also known as expensive junk! ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- H-CLASS NEODYMIUM MEASUREMENTS: 2 INCHES IN LENGTH (50 mm) 1 INCHES IN WIDTH (25mm) 5/16 INCHES THICK. (7.989 mm) (THEY ARE PLAINED TO BE BONDABLE AND STACKABLE, stack of three bonded is 2 inch by 1 inch, by 1 inch) THEY ARE MAGNETIZED THROUGH THIER THICKNESS. THE NORTH FACE OF EACH MAGNET IS INDICATED WITH A SMALL RED FELT TIP DOT (removable) ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- COMPLETE MAGNETIC SPECIFICATIONS: The dimensions of each magnets is 2 inches long x 1 inch wide x 5/16 of an inch thick. They are magnetized through their thickness for use in windmills, generators, magnet motors, alternators, etc. 1-TOLERANCES This batch was commissioned to be manufactured using hyper precise tolerances; unequaled by any magnets you find floating around; they including, amoung other characteristics, a uniform 1mm corner radiusing, Less than .001" variance in thickness and less than .002" variance in length, with a variance in parallelism not to exceed .001"). 2- MAXIMUM OPERATING TEMPERATURE This category (H-class) of neodymium has a maximum operating temperature 54 % higher than the other magnets found on ebay. H-class is used almost exclusively for military and industrial applications. With a maximum operating temperature 100 degrees above standard neodymium, High-temp neodymium magnets are unaffected at temperatures that permanently, and rapidly demagnetize all other classes and categories of neodymium currently available. In addition to their vastly superior operating temperature, and exacting tolerances, they also have a custom 'environmentally ruggedized' finish which is astonishing. 3- RUGGEDIZED FINISH Using a Triple coated Nickel-copper-nickel method of finishing, the plating on these particular magnets are industrial in thickness and consistency. The commissioned requirements of this particular batch required each magnet, and it's plating, to endure savage elemental and environmental abuse. Each batch of this particular run had a sample removed and subjected to a mandatory 50 hour pressurized salt spray test. If the finish was able to handle the entirety of the test without showing any signs of wear, corrosion, or plating failure, then that subunit of the batch passed. In short these magnets were commissioned to be used in astonishingly precise machinery. Machinery and weaponry that was designed to be operated In extremely harsh environmental conditions. They are new old stock US military grade class.... It's goes without saying They are not your normal Neo-block magnets, and when this batch is sold out, neither you, nor I will probably ever see (or be able to afford to buy) magnets of this quality again. Here are their specs. 5- COMPLETE MANUFACTURING SPECIFICATIONS Primary Composition: NeFdB, Neodymium-Iron-Boron Composition of exterior plating: industrial Ni-Cu-Ni Magnetic Grade: N48 Br Max : 14200 Gauss Surface Field (on axis) : 2.837 Gauss Direction of magnetization: through thickness (5/16") Overall Dimensions : 2 inches by 1 inch by 5/16 inches Dimmensions continued: 50mm by 25mm by 7.87 Magnetic Class: H Currie Point (temp of irreversible loses): 590 degrees F Maximum Operating Temp: 243 degrees Tolerances: .002 width, .002 length, .001 thickness Maximum Radius of Edges: 1mm Br Max : 14200 Gauss Surface Field (on axis) : 2.837 Gauss ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- COATING SPECIFICATIONS FROM MANUFACTURER: THEY ARE EACH TRIPLE COATED (INDUSTRIAL HARDENED SPECS.) Layer 1.) NICKEL Layer 2.) COPPER Layer 3.) NICKEL 1.) The industrial, triple coating of nickel-copper-nickel is the finest plating available. Ni-Cu-Ni has superior corrosion resistance and is capable of handling the extremes of outdoor exposure. 2.) This particular plating was manufactured to withstand industrial and environmental abuse. The coating was required to withstand a 50 hour salt spray test, without showing signs of corrosion, blistering, or any other plating failure. 3.) Precision tolerances where upheld during the production of this magnet. Initially manufactured as a component of a larger system, strict guideline for consistency and tolerances where enforced, allowing no corner radius to exceed 1mm. 4.) Even stricter thermal guidelines and tolerance where followed, with each box tested to ensure the entire,product run was true H-class. 5.) These magnets have a safe operating temperature of 248 degrees Fahrenheit...nearly 100 degrees higher than standard neodymium magnets! (These are the only sintered neodymium magnets found in eBay). /li> 6.) Graded at N48, these neodymium magnets are much stronger than N40, N42, and N45 magnets. 7.) Demagnetization curves were required by the manufacturers to be performed on each box. 8.) Strict tolerances of .001" on the thickness, and .002 " on width and length were adhered. 9.)The magnet measures 2 inches long (50mm), 1 inch wide (25mm), and 5/16" thick (7.87mm) (Each Set also includes the reusable impact plastic spacers. Additionally it will be thickly wrapped prior to shipping.) ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- REGARDLESS OF WHERE YOU BUY YOUR MAGNETS FROM.. BE SURE TO KEEP YOUR EYE ON THEIR OPERATING TEMPERATURE!!! DONT MAKE THE SAME MISTAKES AS ME: DON'T BURN UP YOUR MAGNETS Magnets are expensive! PURCHASING REPLACEMENTS IS EVEN LAMER THAN IT SOUNDS. EVEN IF YOU BUY A STANDARD CLASS SET OF MAGNETS FROM SOMEWHERE ELSE.... I've SEEN Solutions Like: Secondary air / liquid cooling systems, PID, Fuzzy logic temperature regulators, external digital temperature gauges, SHUNTS TO PREVENT RUNAWAY HEAT... KEEP AN EYE ON YOUR: windmills, turbines, axial, radial, or another outside-power generating devices! TRUST ME: ITS SAD, EXPENSIVE, AND FRUSTRATING THATS WHY I MOVED OVER TO THE H-CLASS!!! A LITTLE MORE $ PAYS OFF TEN FOLD LATER IN THE SUMMER! BEST OF LUCK WITH YOUR BUILDS... SINCERELY...... JOSHUA FROM THE GREAT NORTHWEST ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- REMINDER: THESE ARE NOT TOYS!!!! MISUSE MAY RESULT IN: GRIEVOUS BODILY HARM, CATASTROPHIC DAMAGE OR EVEN INJURY / DEATH! PLEASE USE EXTREME CAUTION!!!
