Samarium Cobalt Magnet Nickel Plated Galvanized XG28 Magnetized Water High Strength Magnet
Products Description
SmCo5 magnet is composed of SmCo alloy with Sm Co ratio of 1:5. According to weight, Sm accounts for 36% of the total. This SmCo alloy usually contains 36% Sm and a small amount of Co. This series of SmCo magnets can provide a maximum magnetic energy product of 25 MGOe and a reversible temperature coefficient of - 0.05% / ℃. In addition, this series is easier to calibrate to a specific magnetic field than Sm2Co17 series. The Sm2Co17 magnet consists of SmCo alloy with a SmCo ratio of 2:17. It also contains other elements, such as iron, copper, zirconium and hafnium in a small amount. The magnetic energy product of this property is higher, up to 32 MGOe, and the reversible temperature coefficient is - 0.03% / ℃.
1:5 SmCo Magnet
SmCo1:5 Magnet is also called SmCo5, the highest working can be 250℃.Based on Sm,Co and some other metals. After processing of melting, milling, compression moulding and sintering. To make work blank with different levels of performance.
2:17 SmCo Magnet
SmCo2:17 Magnet is also called Sm2Co17, the highest working can be 350℃.Based on Sm, Co, copper, iron zirconium and some other metals. After processing of melting, milling, compression moulding and sintering. To make work blank with different levels of performance.
