Yes BUT... sulfur is optional, potassium nitrate isn't in black powder.

From a corrosive standpoint, depending on the metal, the potassium nitrate is far more corrosive than sulfur.

A word of caution - take the can label literally, since BP sold in the USA is legal to possess ONLY for use in BP firearms. Any other use requires an ATF Explosives User Permit, and you don't want to go there, with required regular inspections of your record keeping and a federally approved storage magazine. I believe Pyrodex (no sulfur to corrode the firearm) is subject to the same regulations.

see the ATF open letter

Can says black powder for black powder firearms., imported from Brazil to Arlington, Texas. I could find no reference to Pyrodex. 4f is used in the flash pan, not the muzzle. I am sure it is the real thing based on instant
ignition and burn time.

Cool, clever substitute. Pyrodex or the real thing? I still have part of a
one pound can of real 4F.

happen to have a pound of Elephant FFFFg.

I had a similar problem igniting a Cadweld that had lost its ignition
powder.

Needing to do 99, on a damp day, a little 2F black powder from the
flintlock shooting kit got them to work every time.
