01.NdFeB Introduction

Ndfeb magnets are rare earth permanent magnet material in the performance of the most prominent magnet. It is made by metal neodymium, iron, boron and other trace elements and through powder metallurgy technology and alloy magnets. Ndfeb with high remanence, high coercivity and high magnetic energy product, cost-effective, and has a very good mechanical and processing properties, so NdFeB magnets are called magnetic King.

The ability of Ndfeb magnet surface oxidation and corrosion resistance is poor, so under normal circumstances plating surface needs to be done. Plating species have phosphating, gold, silver, zinc, nickel, copper, epoxy resin and so on. All of our plating are in line with the EU ROHS requirements.

Ndfeb magnetthe are the third generation of rare earth permanent magnet. The main composition of rare earth metals in Our country is very rich in reserves, production of rare earth magnets account for 70% to 80% of the total world production. In the fierce market competition, KST magnet Co., LTD. The main guest for the field of high-end motor, elector-acoustic,medical equipment,etc, continue to explore,sustainable development,the current performance of our products can reach the level of world-class industry.

01.Ferrite Introduction

Ceramic Ferrite magnet is produced by sintered ceramic technology. The main compositions are Sro,BaO and Fe203. With its competitive cost,ferrite has become one of the most wildly used magnets in the world. Besides it has the good corrosion resistance, so no plating is required.

Ferrite can be molded into cylinder,disk,block and arc shapes.

With consistent and high quality performance, our ferrite products are widly used in electric motors,home appliances and audio products and receive many praises from overseas and inland.

01.Alnico magnet Profile 

Alnico permanent magnet is made up of metal aluminum, nickel, cobalt, tin box other trace element composition of an alloy. Alnico permanent magnets have two different production process: casting and sintering. Casting process can be processed into different size and shape; Compared with casting process, the sintering products is limited to small size, its production of blank size tolerance is better than blank casting products, magnetic is slightly lower than the casting products, but it is better machinability. Alnico has a strong ability to resist corrosion, don't need the plating surface treatment.

Samarium cobalt magnet is a kind of rare earth magnets, is made up of samarium, cobalt and other metallic materials made by the ratio of a permanent magnet, the study successfully in 1970, its main characteristic is magnetic. Temperature resistant performance is good, samarium cobalt magnet has high magnetic energy product, high coercivity, compared with the ndfeb, samarium cobalt magnet is more suitable for working in high temperature environment, samarium cobalt magnet has the very good corrosion resistance, so generally do not need to coating.

However, due to the special molecular structure of samarium cobalt, so more fragile, easy to crack, and the main composition of samarium cobalt samarium reserves on the earth is low, so the price is very expensive. Samarium cobalt according to its composition is different, can be divided into two categories, SmCo5 and Sm2Co17 categories, respectively, for the first generation and second generation rare earth permanent magnet materials.
