    high quality cast alnico u shape magnets/alnico u shapes magnet/u shapes magnets

    01. AlNiCo Magnets Introduction

    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. We can 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.

    Plating:
    Usually supplied in un-plated condition
    If specially requested by customers, we 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 welcome new and old customers to make inquiries.

    02. Cast AlNiCo Magnet


    We supply Cast Alnico magnets with stronger magnetic performance than Sintered Alnico. And cast Alnico permanent magnets can be customized into different sizes and shapes. No surface treatment is needed on Alnico magnets owing to their strong resistance to corrosion and oxidation in extend environmental condition. If some customers think coated Alnico magnets are better for their application, we can coat Nickel or Zn on Alnico magnets. However, coated Alnico magnets look not as beautiful as coated neodymium magnets due to the different material surface and texture.
    The manufacturing process of Cast Alnico magnets mainly includes nine processes. Melting process is special handicraft technology which is not easily controlled. The operators need certain skills and experience to handle it. Material mixing and magnetic heat treatment are key procedures.
    The main manufacturing process of Cast Alnico magnets is listed as follows
    Raw material → Mixing → Melting → Molding Casting → Heat Treatment → Magnetic Testing → Grinding → Inspection → Finalpermanent magnet

    03. Sinter AlNiCo Magnet

    According to the different manufacturing process, alnico permanent magnet material can be divided into two main series of Cast Alnico magnet and Powder Sintered Alnico magnet.
    Powder Sintered Alnico series is divided into isotropic Alnico and thermo magnetic treatment anisotropic Alnico.

    Sintered Alnico magnets are slightly weaker than Cast Alnico magnets in magnetic strength, but their sizes and dimensional tolerance are relatively smaller than cast ones.
    Sintered Alnico magnets are more often used in micro/small motors, permanent magnet motor, relays and some small instruments.

    Sintered Alnico magnets are made from powdered mixture of raw materials that are pressed into a die under tons of pressure. They are then sintered in a hydrogen atmosphere and cooled in an anisotropic or isotropic environment.

    The main manufacturing process of Sintered Alnico magnetic materials is listed as following.
    Raw material → Mixing → Powder → Pressing → Sintering → Heat Treatment → Magnetic Testing → Grinding → Inspection → Final Alnico magnet
