Product Details:

We specialize in the manufacturing, supplying, and exporting of Alnico Magnets (Aluminum-Nickel-Cobalt), known for their excellent temperature stability and high residual induction. Alnico magnets are characterized by high magnetic energy and are primarily composed of aluminum, nickel, and cobalt alloys, often with additions like iron and copper.

Alnico magnets are produced in two main ways: casting and sintering.

Cast Alnico Magnets
• Can be formed into complex shapes (e.g., horseshoe)
• Most popular grade: Cast Alnico 5
• Used in rotating machinery, instruments, sensors, and holding applications

Sintered Alnico Magnets
• Slightly lower magnetic properties than cast types
• Better mechanical strength and uniformity
• Ideal for precision applications

Due to the hard and brittle nature of Alnico, conventional drilling/machining is not recommended. Holes are cast in, and parts are produced close to final size before finishing. Alnico also has low coercive force, so it must be handled carefully to avoid demagnetization.

Tip for best performance: Magnetic length should be at least 5 times the pole diameter (especially for Alnico 5).

We specialize in the fabrication, manufacturing, supplying, and exporting of high-quality Alnico magnets in India. These magnets are primarily composed of aluminum, nickel, cobalt, copper, iron, and occasionally titanium. Known for their high temperature stability, strong magnetic output, and durability, Alnico magnets are ideal for a wide range of industrial and electronic applications.

• Sintered Alnico
Made from a powdered blend of raw materials that are pressed under high pressure and sintered in a hydrogen atmosphere. Cooling can be done with or without a magnetic field:
– Anisotropic (cooled in a magnetic field)
– Isotropic (cooled without a magnetic field)

• Cast Alnico
Manufactured by melting and pouring the alloy into molds. After solidification, the magnet is heat-treated and cooled—sometimes in a magnetic field (anisotropic) to align magnetic domains for maximum magnetization.
Post-processing includes grinding to precise tolerances and magnetizing the material.
