Provided is an Alnico alloy that is lean (i.e., lower) in Co content and yet at least retains substantially the same or better magnetic properties as the corresponding more costly, commercially available Alnico grade alloy with higher Co content, such as grades 8 and 9, which include 31.5 atomic % or more Co, in order to save significant material costs.
