Iron oxide is used as the main material of these ceramic magnets, with strontium carbonate or barium carbonate used as an auxiliary material. These magnets are also manufactured by powder metallurgy.
Ferrite magnets offer the most excellent cost performance of all magnets. Made of ceramics, these magnets are advantageous in terms of chemical stability and not being subject to rust. Since the temperature changes of Br are relatively large, these magnets require a design that allows for the temperature environment. The temperature changes of Hcj are opposite those of rare-earth magnets and other metal magnets, thereby requiring sufficient caution regarding demagnetization at low temperature.
As for cut products, we can cut the base material to the dimensions desired by magnet users. Since grinding is employed, no mold is necessary, thereby making a speedy response possible both in prototyping and mass production.
The maximum dimensions of the base material are 150 x 100 x 25.4 (mm).

(1) Base material can be cut to the type W or type D.
(2) We can supply molds for ring-type, segment-type or other types of products needed by our clients by taking full advantage of our domestic and international network. Molds can be manufactured at surprisingly low cost.
