   Ferrite magnets, also called ceramic magnets, have a high level of hardness, being more fragile and sensitive
to possible beating or bending of the material in some of their handling processes. They are the most economical
magnetic solution that can be found in several applications, thanks to their properties and their low cost.
    Ferrite magnets are the cheapest in the market. Its visual appearance is of a metallic oxide of dark gray color.
They have a great resistance to corrosion and therefore, they are one of the most appropriate products for different
outdoor applications thanks to being stainless. They can also be exposed to temperatures of up to 250ºC. They are
probably the best alternative to neodymium magnets, as they not only resist humidity and corrosion, but are also
resistant to different types of chemicals.
