ZJM-Advance alnico & SmCo magnets, High-tech, spcialized in producing Alnico 5DG (LNG52) , Alnico 5-7 (LNG60) and Alnico 9(LNGT72-LNGT82) magnets as well as Sm2Co17 (YXG30) magnets, and NdFeb Magnets (N35-N52-N35EH).
Alnico Magnets
Alnico magnets are composed primarily of alloys of aluminum, nickel, cobalt, copper, iron, and sometimes titanium, which possess characteristics like high residual induction and excellent temperature stability . Alnico products are widely used in applications such as meters, motors and sensors. Alnico magnets have a variety of shapes and sizes. Some of the common shapes are blocks, discs, rings, horseshoes, bars and holding magnets. Some of them can be painted with red or blue.
High residual induction Excellent temperature stability Wide range of working temperatures, up to 550C Good corrosion resistance Wide range of complex shapes and sizes available Can be plated or painted Ease of magnetization High field strengths at medium prices Lower initial tooling costThe coercivity values, the high remanence and thermal stability of Alnico make it the most cost effective material for certain applications:
Micro Motors Seismo-Sensors Hysteresis BrakesElectronic devices Instrument Making Meters: odometer, electrical meter, water-meter, etc. Audio and SpeakersPrecise Instruments for Aerospace and defense TechnologiesCasting and Sintering are two major processes used to manufacture the Alnico magnets.
