Could be dried water spots, try moving the sprinkler.
Is it powder coated or anodized or painted or vinyl coated?
Aluminum oxide is white and powdery. Paint over it.
if it's bare aluminum, what you're seeing is aluminum oxide. Aluminum doesn't rust like iron, but it DOES oxidize. I'm guessing you have aluminum that's anodized to give it the black color rather than painted and that the anodizing has some small defect areas or pinholes that aren't covered. You might try to get some warranty from the installer (or supplier if you installed it yourself).
