They sure are.

Vendors recommend a 4:1 length to width ratio on pieces of Alnico's 2 thru 6 so they are more resistant to demagnetization.

Ceramics, Alnico's 8 and higher are more immune to size and shape restrictions. This allows Joe Barden's C5 magnets can have an almost square aspect.

"Do any of you use "keepers" or anything for storing the magnets until use? Any special care other than "keep them arranged like they want to be arranged"?"

MagnetSource said that Alnico 5 rods were fine if you had at least two of them stuck end-to-end.

I set them flat (not standing) on an iron strip and they seem okay.
