Yes, it is a bridge rectifier.. If you use two of the four diodes within, you'll have the results I had mentioned. These are cheap and mass produced. I have been a full time electronics technician since 1984, never have seen one failed. They appear in a lot of equipment in the AC to DC power conversion circuits (power supply section). Heavy duty, reliable, and dirt cheap. If you check to make sure it's a fast enough part (most aren't) they'll make a suitable rectifier for an alternator also. Usually they are meant for 120 switching events per second or less as a normal speed (60hz). Depending on design an alternator might need to switch several thousand times a second (that high pitched whine you might have heard).
