The process of alnico magnet manufacturing is
unique and is very popular for use in industries
and is produced using different processes like
casting and sintering. It is so called because it
is a composition of aluminium, nickel and cobalt,
also including copper and sometimes titanium.

Many factors result in its popularity

• It has excellent stability under extreme
  temperatures and also has a high residual
  induction unlike ceramic magnets.
• Unlike other magnets it can be produced in a
  variety of shapes including horseshoes, blocks,
  disks etc. and have a high resistance to
  corrosion.

• These magnets are used in sensing devices and
  holding applications. Also meters and machinery,
  electric motors and are popularly used in guitar
  pickups.
• As alnico magnets are hard and brittle, it needs
  a special process for production as it cannot be
  drilled or machined by the normal procedures.

• Its alloys are ferromagnetic and have a high
  resistance to loss of magnetism and are therefore
  used in permanent magnets.
• Casting the magnet requires treatment with
  various heat cycles after being poured into a
  cast. This creates a dark colour and gives the
  magnet a shiny appearance.

• Sintering requires pushing powdered alnico into a
  press and then sintering it which turns it into a
  solid.
