What is a Grade N52 magnet?

N52 is shorthand for a neodymium magnet grade with an energy product or BHMax of 52MGOe (MGOe stands for Mega-Gauss Oersteds). N52 neodymium magnets are made from one of the most expensive grades and in some instances, a lower grade of neodymium will offer adequate performance at a significantly lower price.

What are N52 magnets used for?

In the field of information technology, neodymium magnets are particularly used in hard disc drives, mobile phones, video and audio systems of television [1]. Neodymium magnets are also commonly used in magnetic separators, filters, ionizers, in production of on–off buttons, safety sector and security systems.

What does the N number mean in magnets?

The grade, or “N rating” of the magnet refers to the Maximum Energy Product of the material that the magnet is made from. It refers to the maximum strength that the material can be magnetized to.

Which is stronger N35 or N52 magnet?

NIB magnets come in different grades, which correspond to the strength of their magnetic fields, ranging from N35 (weakest and least expensive) to N52 (strongest, most expensive and more brittle). An N52 magnet is approximately 50\% stronger than an N35 magnet (52/35 = 1.49).

What is N35 grade magnet?

N35 magnet is a neodymium magnet grade commonly used by our customers. Its magnetic force can meet the requirements of a large number of our customers, and its price is not too high, so it is used in various industries. N35 magnet is just one of the grades of neodymium magnets.

How are N52 magnets made?

Production. Sintered Nd-magnets are prepared by the raw materials being melted in a furnace, cast into a mold and cooled to form ingots. The ingots are pulverized and milled; the powder is then sintered into dense blocks. The blocks are then heat-treated, cut to shape, surface treated and magnetized.

Which magnet is stronger N35 vs n50?

The difference between n35 and n50 magnets is the maximum strength that they can be magnetized to. The basic principle is that the higher the number the stronger the magnet. N35 is, therefore, the weakest and n50 the strongest of the neodymium magnets.

What is stronger N42 or N52?

You can get the same strength as an N52 magnet by using a slightly larger N42 magnet. If you have slightly elevated temperatures, in the 140°F to 176°F range (60°C -80°C), N42 magnets might actually be stronger than N52. This is especially true if your magnet shape is very thin.

What is the difference between N50 and N52 magnets?

Grades of n-magnets It tells you which grade of strength the magnet contains. The different grades of n-magnets are as followed: N35, N38, N40, N42, N45, N48, N50, and N52. The lowest number, which is N35, is the weakest magnet. The N52, which is the highest number, is also the strongest magnet.

How strong is N52 magnets?

Grade N42 magnets have a Br of 13,200 Gauss, while N52 magnets can be as high as 14,800 Gauss. See our Specs page for more Br values for various neodymium magnet grades. The Surface Field is the strength of the magnetic field measured right at the surface of the magnet.

What is neodymium used for in everyday life?

Neodymium is also used in tanning beds because it lets the UV light pass through, but filters out the warm infrared light. When neodymium is incorporated into crystals in lasers, it forms a green light. These lasers are used in laser pointers, eye surgery, cosmetic surgery, and cancer treatments.

What is a N52 magnet?

N52 Magnets. It is a rare earth magnet made from an alloy of iron, boron and neodymium . Needless to mention that N52 magnets have successfully replaced many magnets in sectors such as hard disk drives, magnetic fasteners and cordless tools in motors. Its tetragonal crystal structure renders it highly resistant to being demagnetized.

Where to buy neodymium magnets?

MagnetShop.com carries a large inventory of licensed, neodymium Rare-Earth magnets available for immediate on-line purchase at bulk discounted prices. We offer neodymium discs, rectangular or square neodymium blocks, bars, rings and rods, in a wide range of sizes, premium grades and finishes.

How are neodymium magnets made?

Neodymium magnets also known as NIB magnets are made from a composition of Neodymium, Iron and Boron . The powdered mixture is pressed into molds under great pressure. The material then undergoes the sintering process during which it is heated in vacuum. It is then cooled and then ground or sliced into the desired shape.
