The Royal 90 and 100 have been discontinued. The suggested replacement is the Crown Royal 110 FCO where the flux is built into the middle of the rod - so no more need to have separate rod and flux.

Royal 90 is used for surface brazing of aluminum plate or castings; filling of blow or sand holes; building of worn sections such as gear teeth. Royal 90 can not be anodized.
