3) Aluminum-nickel-cobalt magnet
Aluminum-nickel-cobalt magnets are alloys consisted from aluminum, nickel, cobalt, iron and other trace metal elements. Its casting can be processed into different sizes and shapes with good machinability. Cast al - Ni - Co permanent magnets have the lowest reversible temperature coefficient, its operating temperature can be up to 600 degrees Celsius. Al-ni-co permanent magnet products are widely used in various instruments and other applications.
Classification of al - Ni - Co magnets: it can be divided into cast Al - Ni - co and sintered Al - Ni - Co magnets.
Aluminum-nickel-cobalt applications: Casting aluminum-nickel-cobalt products are mainly used in automotive parts, instruments, electroacoustic device, electrical parts, teaching device, aerospace and military fields, etc., with low temperature coefficient, high temperature resistance, moisture resistance, it is characterized with strong anti-oxidation and good working stability. Sintered al-Ni-Co is produced by powder metallurgy, suitable for the production of complex shape, light, thin, small products used in instruments, communications, magnetoelectric switches and various sensors.
Aluminum nickel cobalt magnet shape forming: it can be cylindrical, circular, rectangular, flat etc.
4) Samarium cobalt magnet
Samarium cobalt magnet is also called samarium cobalt magnetic steel, samarium cobalt permanent magnet, samarium cobalt permanent magnet, samarium cobalt strong magnet and rare earth cobalt permanent magnet, consisted of samarium, cobalt and other rare earth metal material.
This alloyed maget, after smelting, grinding, molding, sintering, has high magnetic energy effect, low temperature coefficient, its highest working temperature up to 350 ℃, no negative temperature, its operating temperature could be above 180 ℃, the maximum magnetic energy power and temperature stability and chemical stability are all higher than ndfeb permanent magnet materials due to its strong corrosion resistance and oxidation resistance; So it is widely used in aerospace, national defense, microwave devices, communications, medical equipment, instruments, meters, various magnetic transmission devices, sensors, magnetic processors, motors, magnetic cranes and so on.
Production process of samarium cobalt magnet: batching → melting ingot → powder making → pressing → sintering tempering → magnetic testing → grinding → pin cutting → finished product
Typical samarium cobalt magnets forming: disc, ring, square, square, tile, special shape could be bespoke based on customization.
