Yes. You may dilute it more than you would for color for even increased economy. Or, if you use it at color dilution, you can expect shorter fixing times than with most typical B&W fixers.

It is a neutral ammonium thiosulphate based fixer, so it's perfect for those who want to use neutral fixes anyway. Compared to acidic BW fixers, neutral ones have less headroom for "oops, I'm an idiot and came from developer directly to fixer without using stop or water rinse" errors and you cannot add hardener additives to neutral fixes. On the other side, people who use pyro developers and want to sustain maximum stain use neutral fixes. Also, neutral fixers are a bit more quick to fix and wash out from film and paper. Otherwise, it does not matter.
