2022 Introduction of common commercial magnetic materials

2022 Introduction of common commercial magnetic materials.There are differences between the varieties and grades of magnetic alloy materials. Each type of permanent magnet material has its own unique advantages and disadvantages.SourceRare earth magnet-https://www.rare-earthmagnet.com/2022-introduction-of-common-commercial-magnetic-materials/

A brief description of the commercially available magnetic materials is listed below.

Samarium Cobalt magnets (SmCo) and Neodymium Iron Boron magnets (NdFeB) are called rare earth magnets because Neodymium and Sa are found in the rare earth elements of the periodic table. samarium cobalt and neodymium magnet alloys are powder metals that are compacted under a strong magnetic field and then sintered.SourceRare earth magnet-https://www.rare-earthmagnet.com/2022-introduction-of-common-commercial-magnetic-materials/

NdFeB magnet is a neodymium magnet, composed of neodymium iron and boron, which is moderately priced. Due to the poor corrosion resistance, NdFeB magnets are usually plated or coated (e.g. nickel plated, epoxy coated, poly-p-xylene coated). The operating temperature range of neodymium magnets depends on your application (80°C to 200°C). High quality neodymium magnets capable of operating above 120°C can become very expensive. This permanent super magnetic material has many intellectual property rights associated with it and there are a limited number of licensed manufacturers in the world. This magnetic material is so powerful that it can miniaturize many products from HDDs (hard disk drives) and motors to novelty and audio devices. When comparing price and performance, neodymium permanent magnets often offer the best value.SourceRare earth magnet-https://www.rare-earthmagnet.com/2022-introduction-of-common-commercial-magnetic-materials/

Samarium Cobalt is another rare earth magnet, consisting primarily of cobalt and samarium, and is the most expensive magnetic material to manufacture and fabricate. Most of the cost is attributed to the high cobalt content and the brittleness of the alloy. This permanent magnet material is highly resistant to corrosion and can withstand temperatures up to 350°C. Samarium Cobalt magnetic materials are widely used in the aerospace market or in industrial applications where performance is a priority and cost is a secondary concern. Samarium Cobalt is the second strongest magnetic material with excellent resistance to demagnetization.SourceRare earth magnet-https://www.rare-earthmagnet.com/2022-introduction-of-common-commercial-magnetic-materials/

The ceramic magnet material (ferrite) is strontium ferrite. Ceramic magnets are one of the most cost effective magnetic materials manufactured. The reason for the low cost is the cheap, abundant and non-strategic raw materials used to make the alloy. Permanent ceramic magnets are useful for mass production. Ceramic magnet materials (ferrite) have good corrosion resistance and can operate at moderate heat. Most of the world's ceramic magnet materials come from China due to the commodity nature of the alloy and the high processing costs in Western countries. Ceramic (ferrite) magnets have a low energy product and are typically used in components containing mild steel.SourceRare earth magnet-https://www.rare-earthmagnet.com/2022-introduction-of-common-commercial-magnetic-materials/

Alnico magnet alloy is mainly composed of aluminum, iron, cobalt and nickel. Due to the cobalt and nickel content, Alnico is a moderately priced magnet material. Alnico magnet alloys have the highest maximum operating temperatures and very good corrosion resistance. Some grades of Alnico alloys can operate at temperatures above 550 degrees. Magnets made from this alloy are available in various grades and sizes and are usually cast and polished to a certain size. alnico magnet material is an older technology that has a lower energy product (BHmax). Alnico magnet alloys are now used primarily in military, aerospace, older proprietary designs and in applications where the magnets will be exposed to high temperatures.SourceRare earth magnet-https://www.rare-earthmagnet.com/2022-introduction-of-common-commercial-magnetic-materials/

Bonded magnet materials can be made from ceramic, NdFeB or SmCo powders and used in combination with a variety of plastic binders (substrates). They can be either injection molded or compression bonded into complex magnet shapes with final dimensions. Bonded magnet materials have moderate corrosion resistance and low heat resistance due to the bonding material. Bonded magnets are commonly used for automotive parts because they can be produced in large quantities and can be produced in complex shapes at low cost.SourceRare earth magnet-https://www.rare-earthmagnet.com/2022-introduction-of-common-commercial-magnetic-materials/
