Co-Reduced
The manufacture of samarium cobalt alloys via the co-reduction of an oxide mix is a specialised process yielding very fine-grained high performance alloy powders. Co-reduction has now become the industry standard for SmCo5 production; the capability of this process also extends to the manufacture of Sm2Co17 powders, where the product type can provide significantly improved processing performance for customers.
