Why ALB Magnets?

Magnets Reliable quality, ALB Magnets has been involved in R&D, manufacturing, and sales of permanent magnets over 10 years. We are the manufacturer & supplier of rare earth permanent magnets such as neodymium magnets(the strong/super magnets) and SmCo Magnets(high temp magnets).

Our powerful magnets are widely used in many different fields, such as motors, relays & sensors, loudspeakers, wind turbines and mechanical devices, etc. We specialize in manufacturing permanent magnets according to customers' requirements in terms of magnetic characteristics, shapes and sizes.

How to choose permanent magnet?

At ALB Magnets we like to think that choosing the right product for your application is a simple and easy process, so how do we do it? We employ a specialist team of technical engineers that work round the clock to provide professional and detailed advice. Unless you ask us to we won’t give you any complicated equations or ask you to calculate any big numbers, we’ll do all that for you. Simply tell us about your project and we will supply you with the right magnet.

What are Neodymium Magnets?

Neodymium magnets are often referred to as "NdFeB" or "Neo". First discovered in 1982 and commercially available in 1984 Neodymium magnets have largely become the most widely used type of rare-earth magnet around the world. They are manufactured from an alloy of neodymium, iron, and boron (NdFeB). Although relatively small in size they are known for their incredible strength. Neodymium magnets are technological marvels, is the strongest permanent magnet in the world, Neodymium magnets are considered part of the family of rare earth magnets because their main element is the rare earth element, neodymium. Despite the name, rare earth elements are relatively abundant in the Earth’s crust, however, they are rarely found in their concentrated form, and rather they are typically dispersed with other elements.

Are Neodymium Magnets really that strong?

Yes, they are. Neodymium (also described as rare-earth magnets) magnets are the strongest commercially available. They possess an extremely high magnetic pull and in some cases (the very strong ones) can cause severe injury. stronger grades of neodymium magnets have become commercially available as manufacturing techniques have become more advanced. The strongest grade currently available is the N55, although it is not yet widely used. More common are N42 and N52 grades; a 2 inches x 2 inches x 1 inches thick N52 neodymium block is capable of supporting a steel weight of 115Kg vertically when in flush contact with a mild steel surface of equal thickness and produces a Gauss rating, the unit measurement of flux density, of 5,500 over 7,800 times stronger than that produced by the Earth at its magnetic poles. Electromagnets which harness electric currents to produce magnetic fields can be many times stronger than permanent magnets, however, they need a significant electrical current to produce their magnetic field.

How are Neodymium Magnets Manufactured?

The main ingredients of a neodymium magnet are neodymium, iron, and boron; the chemical compound known as NdFeB. The exact ingredients depend on the grade or strength of the magnet being produced. At albmagnets.com, we do not compromise on quality, the majority of our magnets are grade N42 or above, making them 20% more magnetic than many cheaper N35 grade magnets on the market. Unlike many other magnet suppliers, we also add an element called dysprosium, which replaces some of the neodymium - dysprosium has the highest magnetic strength of all elements and is added to all our neodymium magnets raising the coercivity of the material and increasing their resistance to demagnetization and corrosion.

Every magnet sold by albmagnets.com is quality assured before it is dispatched to the customer to be used in hundreds of different applications.

How to choose and buy a strong neodymium magnet? ALBMagnets is a professional company for strong magnet design and manufacturing,
providing you with reliable N35, N38, N42, N52, N42SH and other grade super neodymium magnets and SmCo rare earth magnets.
