Alnico magnets are made of aluminum, nickel, cobalt, copper, iron and other materials. Based on different processing technology, it can be divided into cast and sintered magnets. China Rare Earth Magnet Limited supply both cast and sintered alnico magnets in a variety shapes including horseshoe, U shape, bar, block, disc, ring, rod and other customized shapes. Compared to other permanent magnets like neodymium iron boron (NdFeB), the main features are excellent resistance to high temperature (up to 550℃) and high residual induction.
Usually supplied in un-plated condition
If specially requested by customers, China Rare Earth Magnet Limited can plate alnico magnets with NiCuNi. But as it has weak adhesion to plating, NiCuNi plating might flake off if not handled properly.
Cast alnico magnets are mainly applied in automotive parts, instruments, electro-acoustic, electrical, teaching equipments, aviation and military areas. Sintered Alnico magnets are widely used in fields of instrumentation, communications, electronic, magnetic switches, sensors and others.
Given the low coercive force of alnico permanent magnet , in order to avoid irreversible demagnetization or disorder of magnetic flux distribution, alnico magnets shall be strictly kept apart from other magnetic materials in actual application or shipping process, especially neodymium magnet material.
With the principle of quality, credit, price concessions and prompt delivery, we warmly new and old customers to make inquiries.
