Sm2Co17 High Temperature Samarium Cobalt Magnets 1" x 3/8" x (3/8)", Orientation through the Thickness – Lot of 15 This is a high temperature magnet rated for a maximum operating temperature of 350°C (663°F). Key Information: Size: 1.000" x 0.375" x (0.375)" Grade: Sm2Co17 Pull Force: 12.0 lbs (Estimated) Maximum Operating Temperature: 350°C / 663°F Plating: None Shape: Block Quantity: 15 pieces per lot This is final remaining inventory from our company as we are closing our operations. We were a trusted supplier of magnetic materials since 1984, shipping to customers throughout the United States, Canada, Mexico, and around the world. Due to major changes in rare earth material availability and pricing, we can no longer competitively service our customers. Note: This high-temperature material has become extremely difficult to source within the US due to import restrictions. Once this inventory is gone, replacement stock is not expected anytime soon. Perfect for applications that require magnets to perform reliably in high heat. Samarium Cobalt will lose it's strength when the operating temperature exceeds 350°C / 663°F but will regain its strength as it cools. This material is also very brittle and must be handles with caution. If machined (not advisable) be aware that this in powder form is flammable.
