Introduction
Permanent magnets are objects made from magnetic materials. They can create their own persistent magnetic fields and be strongly attached to ferromagnetic substances like iron, nickel, cobalt, etc. Magnets with permanent fields are either naturally occurring products or artificially produced in labs and factories. There are three types of permanent magnets: neodymium magnets, ferrite magnets and SmCo magnets.
Features
1. They have excellent temperature stability. Their Br temperature coefficient is small.
2. They are featured by compact crystal structure, high intensity, good chemical stability and strong anti-corrosion.
3. The highest usage temperature reaches up to 500 ℃.
Advantages
1. Our permanent magnet products have passed various authentications in past years, such as GB/T19001-2000, ISO9001:2000, GB/T24001-2004, ISO14001:2004, GB/T28001-2001, etc.
2. Magnetic products are featured by large remanence, strong coercivity, large magnetic energy product, high performance cost ratio, etc. Besides, we can shape magnetic materials into different sizes according to customers’ needs.
Applications
1. Permanent magnets are widely applied in electronic industry, electrical industry, mechanical industry, transportation industry, medical field, commodity industry, etc.
2. Magnetic materials are utilized in production of loudspeakers, telephone receivers, alternators, motors, maglev system, magnetic bearings, magnetic separators, magnetron, proton accelerator, etc.
Process
Production of permanent magnets needs various machining processes such as cutting, wire cutting, drilling, milling, turning, etc. Hence, production cost is relatively higher than magnets in ordinary shapes.
Lantoky Magnetic Device Factory (Lantoky Magnetic) is specialized in production of permanent magnet and magnet assemblies. We deliver a comprehensive magnetic materials range, including permanent ferrite magnets and rare earth magnets. Generally, rare earth magnets are produced with complex manufacturing procedures.
