Description

Reviews

SmCo Ring Magnets are mainly include metal material: Samarium and Cobalts Metals.The thin thickness disc or thin wall ring magnets can be obtained by choicing SmCo5 magnets.

The maxmium diameter of these Samarium Cobalt Magnets can up to 120mm.Different dimensions available with different coating.Of course, they always do not need coating because SmCo magnets are high resistant.Axially Magnetized or Diametrically Magnetized can be done according to customer's requirement.

Small Quantities Samples can be supplied with Affordable price to support customer. if you need stronger ring magnets, maybe can choice Neodymium Ring Magnets, but its max working temperture is lower than SmCo ring magnets.

SmCo Ring Magnets Dimension tolerance for reference .
