Product Description
High Strength Samarium Cobalt Ring Magnets - Corrosion Resistance Uncoated
Product Overview
Samarium Cobalt (SmCo) magnets are rare earth permanent magnets known for their exceptional magnetic properties, high temperature resistance, and excellent corrosion resistance. These uncoated magnets operate reliably in extreme environments up to 500°C, making them ideal for demanding applications in aerospace, defense, and industrial sectors.
