Product Description

Alnico Magnets

Owing to our expertise in this domain, we are engaged in offering an excellent quality array of Alnico Magnets. Offered magnets are widely used in mobiles, motors, guitar pickups, telephones, loudspeakers and many more. With the utmost precision and perfection, these magnets are manufactured by employing casting and sintering processes under deft professionals' guidance. In addition to this, the offered Alnico Magnets can be availed from us in diverse shapes like horseshoe, disc, ring, sleeve and cylindrical as per the clients' variegated requirement.
