Ferrite Magnets (Ceramic Magnets), a type of permanent magnets, are produced by calcining a mixture of iron oxide (Fe2O3) and strontium carbonate (SrCO3). The production cost of sintered ferrite, compared with other permanent magnets, is very low. In addition to a low production cost, sintered ferrite is durable under severe environmental conditions and resist corrosion, making it one of the most widely used permanent magnets.
An Alnico magnet has an operating temperature as high as 500℃, making it an ideal option for chemical, aerospace and defense industry that require products to withstand high temperature and retain superior corrosion resistance. Alnico magnets are categorized into cast alnico and sintered alnico. While the former applies to smaller designs, the latter allows for the design of intricate shapes. Alnico magnets can be combined with the plastic or metal parts for various applications.
Samarium Cobalt magnets (SmCo magnets) have two alloy varieties, Sm1Co5 and Sm2CO17, and offer the superior temperature resistance ( BHmax could achieve as high as 29MGOe) at temperature ranging from 250℃ to 350℃. Because SmCo has superior corrosion resistance compared to neodymium magnets, there is no need for SmCo to have an extra protective coating.
Magnetic assemblies are products that combine magnets and casings to implement the lift, hold, or separation of metallic materials. Normally, magnets used in magnetic assembly are ferrite magnets, alnico magnets, samarium cobalt magnets, neodymium magnets, and rubber magnets. In addition to a variety of magnets, we also provide different casing and coating options to enhance corrosion resistance.
