HESHENG MAGNET GROUP

Professional Effective Fast

Fast Delivery Block Nickle Coating NdFeB Neodymium Bar Magnets

Over the last 15 years ，We have been maintaining extensive and in-depth cooperation with many well-known domestic and overseas enterprises, such as BYD, Gree, Huawei, General Motors, Ford, etc.

We accept customized/ODM/0EM ,Sample services！！！

Neodymium( NdFeB )magnets are the type of rare earth magnet commercially available and are manufactured in a wide range of shapes,sizes and grades. Hesheng Magnetics Co., Ltd. was found in 2003 .which is the role-model enterprise among magnets manufacturing industries in China. We own one-step complete industrial chain from raw material blank, cutting, electroplating and standard packing.

As the third generation of rare earth permanent magnet, Neodymium magnets are the most powerful commercially produced magnets. Neodymium arc magnet, also known as Neodymium curved magnet, is a unique shape of Neodymium magnet, then almost all of Neodymium arc magnet is used for both rotor and stator in permanent magnet (PM) motors, generators, or magnetic couplings.

Various Shapes：Any size and performance can be customized according to requirements.The highest accuracy can reach 0.01mm

Magnetic Direction：The magnetization direction of the magnet has been determined during pressing. The magnetization direction of the finished product cannot be changed. Please be sure to confirm the required magnetization direction

Environmental Protection Coating：We have our own electroplating factory, which supports the customization of various coatings and meets the environmental protection standards

In most cases,it is diametrical magnetized,half of quantity is N pole and the other quantity is S pole.

Coating

The following is a list and description of common plating options for custom magnets.Why do magnets need to be plated?

Oxidization (Rust) NdFeB magnets will oxidize(rust) if left exposed. When a plating wears down or cracks, the exposed area will oxidize. An oxidized area will not result in complete degradation of the magnet, only the oxidized area will lose its strength. However the magnet will lose some structural integrity and become more susceptible to breakage.
DurabilityDepending on shape, permanent magnet substrate is brittle. A multilayered metal plating like nickel or zinc improves the magnets resistance to chipping and wear, particularly around corners.
Harsh Environments Platings vary in their tolerance of different harsh chemicals and abrasion. Salt and humidity in regions near the ocean are commonly overlooked when selecting a plating. Be sure to consider the magnets environment when selecting a plating.
The most common type of plating for neodymium magnets Nickel (Ni-Cu-Ni) Intended for indoor use. It has proven to be very resilient when subjected to normal wear and tear. However it will corrode oudoors in prolonged exposure to salt water, salty air,or harsh chemicals.

Application
1). Electronics – Sensors, hard disk drives, sophisticated switches, electro-mechanical devices etc.;

2). Auto Industry – DC motors (hybrid and electric), small high-performance motors, power steering;

3). Medical – MRI equipment and scanners;

4). Clean Tech Energy – Water flow enhancement, wind turbines;

5). Magnetic Separators – Used for recycling, food and liquids QC, waste removal;

6). Magnetic Bearing – Used for highly sensitive and delicate procedures in various heavy industries.

Manufacturing Process

Sintered Neodymium magnet is prepared by the raw materials being melted under vacuum or inert gas atmosphere in an induction melting furnace and processed in the strip caster and thus cooled to form alloy strip. The strips are crushed and pulverized to form a fine powder ranging from 3 to 7 microns in particle size. The powder is subsequently compacted in an aligning field and sintered into dense bodies. The blanks are then machined to the specific shapes, surface treated and magnetized.
