Due to different manufacturing processes these materials (excepting C1) are sourced off-shore for the convenience of our customers. Secondary operations (ie. machining, magnetizing and inspection) are performed here. Ceramic/Bonded are least strong of these grades, of the rare earth magnets, NIB is strongest while SmCo has better temperature characteristics. AlNiCo has the best temperature characteristics, although is less strong than rare earths and is easily de-magnetized.
