Neodymium magnet, also known as NdFeB magnet, is a tetragonal crystal system formed by neodymium, iron and boron (Nd2Fe14B). In 1982, Masato Sagawa of Sumitomo Special Metals discovered neodymium magnets. The magnetic energy product (BHmax) of this magnet is greater than the samarium cobalt magnet, which is the largest magnetic energy product in the world…
1. Chemical Composition: Neodymium Magnets: Primarily composed of neodymium (Nd), iron (Fe), and boron (B), neodymium magnets are a type of rare earth permanent magnetic material. Ferrite Magnets: Mainly composed of iron oxides, typically a composite of magnetite (Fe3O4) and other metal oxides. 2. Appearance Differences: Neodymium Magnets often require electroplating to prevent rust and…
NdFeB magnets are powerful and versatile but are prone to oxidation and corrosion. Taking preventive steps can greatly improve their durability and ensure long-term performance. NdFeB magnets, while exceptionally strong, can rust if not properly protected. Applying coatings, using protective coverings like rubber, and following good storage practices can prevent rust and extend the magnet’s…
What is Hot Work? Hot work refers to any process that generates heat through activities such as welding, cutting, brazing, soldering, grinding, or similar techniques that produce sparks or flames. These processes typically involve using equipment that heats metal to a molten state or generates sparks that can ignite nearby flammable materials. Here are some…
As known to everyone, magnets can attract irons. But do you know can magnets stick to aluminum? Aluminum, a widely used metal in various industries, often sparks curiosity regarding its magnetic properties. Let’s delve into the magnetic nature of aluminum, its characteristics, and whether it is prone to rusting. 1. Is Aluminum Magnetic? Contrary to…
What is Stainless Steel? The Stainless steel, also known as inox, is a corrosion-resistant alloy of iron. It contains at least 10.5% chromium, along with nickel and carbon. The chromium forms a protective film on the surface, providing resistance to rust and corrosion. Stainless steel is abbreviated as stainless acid-resistant steel, indicating its resistance to…
Neodymium magnets, also known as Neodymium-Iron-Boron (NdFeB) magnets, are the strongest type of permanent magnets commercially available. They are widely used in various applications, including Renewable Energy to Medical Imaging, Wind Industry, Oil & Gas Industry, Automotive Industry and Daily Use Applications. The performance of neodymium magnets is characterized by their grade, which provides information…
Over time, metal products tend to be exposed to oxygen and water and rust, forming a coating of iron oxide. This coating, often referred to as “rust,” not only changes the appearance of a metal object but may also affect its performance. However, a curious question is: Can magnets attract these rust stains or Will…
The allure of using fishing magnets to reel in gold has captured the imagination of many treasure seekers, but the reality is far more nuanced. While fishing magnets excel at attracting metallic objects submerged in water, their effectiveness in capturing gold is severely limited. Let’s delve into the reasons why. Is Gold Magnetic? At the…
