Alnico Red-Blue Bar Magnet

Bar Magnet, Alnico Blue-Red - educational Magnets

This strong bar magnet is ideal for science projects or class demonstrations. It is made from an alloy of Aluminum, Nickel and Cobalt (AlNiCo) and it is extremely durable. It produces a very strong magnetic field. It comes with poles painted blue and red. This alnico bar magnet is ideal for magnetic demonstrations in classrooms or for use as a piece of equipment in the laboratory. Alnico is an acronym referring to a family of iron alloys which in addition to iron are composed primarily of aluminum (Al), nickel (Ni) and cobalt (Co), hence al-ni-co. Alnico alloys are ferromagnetic, with a high coercivity (resistance to loss of magnetism) and are used to make permanent magnets. These alnico magnets are carefully painted red, for the north pole, and blue, for the south pole.

What are Alnico Magnets?

Alnico Magnets have excellent temperature stability and are ideal for corrosive and high heat applications up to 930°F (500°C).  Alnico magnets come in different shapes such as cylinder, pot, block and the popular horseshoe. Alnico magnets are commonly used for various types of sensors. We offer both cast and sintered Alnico Magnets in a variety of grades, including Alnico 2, Alnico 5 and Alnico 5-7.

Our large selection of available Alnico magnetic alloys helps achieve the best balance of cost, magnetic performance, and operational temperature resistance for your specific application. Stock Alnico magnets also available to reduce development and production lead times.

Alnico magnets are made of an alloy of aluminium, nickel and cobalt. Alnico magnetic bases offer a wide range of applications in the industrial world. Manufacturing can be by injection, pressing, extrusion or calendering. Our large selection of available Alnico magnetic alloys helps achieve the best balance of cost, magnetic performance, and operational temperature resistance for your specific application.

Alnico's are the strong magnets which can produce strong magnetic fields:

• Excellent resistance to corrosion
• They have superior thermal stability
• These magnets have some of the highest curie points of any magnetic material ranging around 800oC
• Some type of Alnico's are isotropic
• They have high magnetic flux density

Alnico Magnets

Alnico is an alloy produced by mixing aluminum, nickel and cobalt with certain addition of other metals like copper, iron and titanium. Capable of producing strong magnetic field, it has an excellent linear temperature characteristics and has wide industrial applications.

Types of Alnico Magnets

On the basis of manufacturing process and application alnico can be grouped into following types:

• Cast Alnico
• Sintered Alnico
• Bar Alnico

Alnico magnets can be fabricated into many shapes and types:

Manufacturing Process

Casting or sintering process is applied for making alnico magnets. The first step involves the pouring of molten metal alloys into moulds. Later it is passed through various heat cycles. The resultant magnets have rough surface which after machining gives a glossy look. Sintered magnets are produced by compacting fine alnico powder in a press, and then sintering the compacted powder into a solid magnet. Alnico magnets can only be magnetized only in the field having magnetizing fields of about 3 kOe. Since these magnets have low coercivity they, must be protected from the adverse repelling fields as this could partially demagnetize the magnets.

Magnetizing

After the tolerance magnetizing is effected. As alnico magnets are brittle, they must be protected from hard blows and handled with care. It should be magnetized in a proper magnetic field and must be prevented from the repelling fields as it is prone to demagnetization.
