These disc-type holding magnets have a ring made of the metallic magnetic material Alnico. They are designed for application where height is too restricted for conventional deep pot magnets. A magnet with counter hole assembled in a mild steel pot by spacer or tree points press fixing. Alnico shallow pot magnet can be continuously used up to a temperature of + 500 °C. North polarity in center of holding face and each magnet has a coated keeper. Outer surface except pole can be red (smooth or wrinkle) painted, or coated with Zinc, Nickel or Chrome. However, the stability against demagnetization is not as high as deep pot holding magnets. Only fix with countersunk screws made of non-magnetic materials, e.g. brass or stainless steel.
