YCo5 is an intermetallic compound in the yttrium-cobalt system, forming a hard, brittle metallic phase with hexagonal crystal structure. It is primarily used in permanent magnet applications and high-temperature structural components where its exceptional hardness and thermal stability are advantageous. YCo5 is notable for its strong magnetic properties and resistance to oxidation, making it valuable in aerospace and automotive contexts, though its brittleness limits it to applications where ductility is not critical.
