Ideal for high-performance applications like electric motors, turbo machinery, and sensors, these corrosion-resistant rare earth magnets combine precision manufacturing with exceptional durability, making them a must-have for professionals demanding reliability in extreme conditions. ## Description Pack of 1020mm diameter x 3mm thick+/-0.1mm toleranceEach magnet's north and south pole are on opposite 20mm diameter facesExcellent resistance to demagnetisationSuperior resistance to corrosionMaximum operating temperature of 300℃These medium-sized samarium cobalt disc magnets maybe thin but they are incredibly dependable. Samarium cobalt is a type of rare-earth magnet that has the ability to withstand and operate in high temperatures and has a superior resistance to corrosion, however they are not as powerful as super-strong neodymium magnets. Because of their high maximum operating temperature they are most often used in applications such as motors and electric motors, turbo machinery and sensors and because of their corrosion resistance they are ideal for use outdoors.  ## Features - HIGH MAXIMUM OPERATING TEMPERATURE. Samarium cobalt has a maximum operating temperature of 300 degrees Celsius these magnets are perfect for high-temperature applications. - MULTIPLE USES. Because of their high maximum operating temperature, they are commonly used in applications such as motors and electric motors, turbo machinery, and sensors. - IDEAL FOR OUTDOOR USE. Samarium cobalt has a superior resistance to corrosion and demagnetisation they are ideal for use outside. - STRONG RARE EARTH MAGNET. Each magnet can support a steel weight of up to 3kg vertically from the magnetic face when in flush contact with a mild steel surface. - SPECIFICATIONS. 20mm diameter x 3mm thick. +/-0.1mm tolerance. Each magnet's north and south pole are on opposite 20mm diameter faces. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0785FC7C8 | | Best Sellers Rank | 158,749 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 964 in Rare Earth Magnets | | Brand | FIRST4MAGNETS | | Colour | Cobalt | | Country Of Origin | China | | Customer Reviews | 3.4 3.4 out of 5 stars (14) | | Global Trade Identification Number | 05055641228585 | | Item Shape | Round | | Item Type Name | Magnet | | Manufacturer | Magnet Expert | | Manufacturer Part Number | F406SC-10 | | Material Type | Sm2Co17 | | Model Number | F406SC-10 | | Number of Items | 10 | | Number of Pieces | 10 | | Pull Force | 3 Kilograms | | Unit Count | 10 Magnet | ## Product Details - **Brand:** FIRST4MAGNETS - **Colour:** Cobalt - **Material:** Sm2Co17 - **Number of pieces:** 10 - **Shape:** Round ## Images ![Samarium Cobalt Magnet for Motors, Electric Motors, Turbo Machinery and Sensors - 20mm dia x 3mm thick - 3kg Pull - Pack of 10 - Image 1](https://m.media-amazon.com/images/I/41ODiY88GfL.jpg) ## Available Options This product comes in different **Size** options. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/98693570-samarium-cobalt-magnet-for-motors-electric-motors-turbo-machinery-sensors](https://www.desertcart.tn/products/98693570-samarium-cobalt-magnet-for-motors-electric-motors-turbo-machinery-sensors) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-11-15*
