If these are die-cast aluminum, then pitting is all to common for the process. A vacuum draws the molten metal into the die cavity. If there is any leakage in the die cast seal tiny bubbles (pitting) will form. There are many other reason for this as well but it is not relevant to this topic. Long story short it could be corrosion it could be pitting either way it is near impossible to get out.
