ALNICO
MAGNETS
Alnico magnets are made
primarily from Aluminum, Nickel and Cobalt. They may also contain copper, iron and sometimes titanium. We
only offer magnetically strong ALNICO cow magnets (Grade 5).

ALNICO BAR MAGNETS, Painted
and Marked
These bar magnets measure
about 1/4" x 1/2" x 3" (72 x 12 x 6 mm). The magnets are made of Aluminum (8%),
Nickel (14%), Cobalt (24%), copper (3%) and Iron (51%) which makes for a super
strong and high quality magnet
 |
ALNICOPBM70 has color
coded poles that are also marked with S and N for easy
identification of the poles. May be used for educational experiments
and industrial applications.
Bar magnets are sold individually,
but it is cheaper if you buy a pair.

ALNICO
Cow Magnets:
Cow magnets are rod
magnets with rounded ends. They are usually about 3" (75mm) long and
1/2" (12mm) diameter. These are popular with dairy farmers and
veterinarians to help prevent Hardware Disease in their cattle. While grazing,
cows eat everything from grass and dirt to nails, staples and bits of bailing
wire (referred to as tramp iron). Tramp iron tends to lodge in the honeycombed
walls of the reticulum, threatening the surrounding vital organs and causing
irritation and inflammation, known as Hardware Disease. The cow loses her
appetite and decreases her milk output (dairy cows), or her ability to gain
weight (feeder stock). Cow magnets help prevent this disease by attracting stray
metal from the folds and crevices of the rumen and reticulum. One magnet works
for the life of the cow!
Cow magnets are also
one of the most favorite shapes of magnet for science experiments.
Students use the cow magnet to make electric generators, observe magnetic
lines and perform other magnet related experiments.

| For All
Uses (Science Experiments, Cows and Industrial Applications)
COWMAG is our highest quality ALNICO5 cow
magnet made by casting method from molten alloy. It has a smooth surface
and the ends are rounded by grinding. COWMAG is the strongest ALNICO
magnet with 24% cobalt.
COWMAG provides both physical strength
and magnetic strength.

COWMAG may be used for cows,
science experiments and industrial uses as long as it is protected against
excessive force.
COWMAG magnets are 3" long
and 1/2" in diameter. (D12.63 x L76.2mm)
No more sintered ALNICO
magnets!
Sintered ALNICO magnets have similar magnetic strength
as casted ALNICO magnets; however, they lack physical strength because they are
made of compressed metal powder. Sintered magnets brake if fallen on a hard
surface. We no longer carry sintered ALNICO magnets.
