Sunight Magnetics offer a variety of high-performance magnetic materials and products to meet the needs of different industries and applications.
Samarium Cobalt (SmCo) magnets are rare earth permanent magnets and part of the lanthanide alloy family, similar to NdFeB magnets. They are available in various grades to suit different applications, providing designers with high magnetic strength, excellent thermal stability, and good corrosion resistance.
AlNiCo (Aluminum Nickel Cobalt) magnets were originally developed for meters and instruments and are renowned for excellent temperature stability, high residual induction, and relatively strong magnetic energy, a technology dating back to the 1930s. Within the AlNiCo family, both isotropic and anisotropic magnets can be produced by adjusting alloy composition and manufacturing methods.
Hard ferrite magnets, also known as ceramic magnets, are made primarily from iron oxide (Fe₂O₃) combined with barium or strontium carbonate. They are produced through sintering or pressing methods to form strong, permanent magnets.
NdFeB magnets, also known as neodymium magnets, are rare-earth permanent magnets made from an alloy of neodymium, iron, and boron. They are the strongest commercially available permanent magnets, offering extremely high magnetic energy products.
Magnetic assemblies integrate magnets with metal and non-metal components to create functional products or semi-finished parts, such as motor rotors, sensors, magnetic filters, lifters, pumps, and speakers. Sunight Magnetics specializes in converting customer designs into high-quality magnetic assemblies. Through professional assembly services and integrated supply chains, we help reduce costs, shorten production time, and improve manufacturing efficiency.
Flexible magnets are made from ferrite or rare-earth magnetic powders mixed with rubber or plastic binders and formed into sheets, strips, or rolls. They can be easily cut, bent, and shaped while maintaining stable magnetism. With good flexibility, corrosion resistance, and cost efficiency, flexible magnets are widely used in advertising displays, seals, labels, sensors, and light-duty industrial applications.
Bonded SmCo magnets are made by bonding samarium cobalt magnetic powder with polymer binders. They offer excellent thermal stability, strong corrosion resistance, and reliable magnetic performance. Suitable for complex shapes and flexible magnetization designs, bonded SmCo magnets are ideal for high-temperature, high-reliability applications in motors, sensors, and precision electronics.
Bonded NdFeB magnets are produced from microcrystalline NdFeB powder bonded with polymers or other binders, forming compact isotropic permanent magnets. Although their magnetic energy product is lower than that of sintered NdFeB, bonded NdFeB magnets offer excellent design flexibility and manufacturing efficiency.
Bonded ferrite magnets, also known as plastic magnets, are made from ferrite powder and polymer resin through injection or compression molding. They offer high dimensional accuracy, stable performance, and flexible magnetization options, making them ideal for precision micro motors, sensors, and automation applications requiring reliable and durable magnetic sources.
Sunight Magnetics offers high-strength magnets widely used in automation, automotive, electronics, renewable energy, and home appliances.
