     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.
   The working temperature is a factor to be taken into account in the different uses that will be given to the magnet.
We can offer our customers a wide range of magnets that cover temperatures from -40ºC to 250ºC.

Production Process
    To obtain the ferrite magnet, first, it must undergo different phases of the production process, in this way to ensure its
quality; The process begins in obtaining the ferrite by heating a mixture of different metal oxides at high temperatures.
Once the ferrite is obtained, the product is ground into very small particles, so that each molecule has only one magnetic
domain. The powder is pressed with a concrete shape and dry, in this way smaller and geometric shapes are achieved.

Next, the material obtained is subjected to sintering, in a situation with oxygen shortage. To avoid that the pieces stick with
each other in the oven, we proceed to install some sheets that will make separators. This process is very important since it
directly influences the magnetic properties of the ferrite and can cause cracks, bubbles and some deformation.
