They are worried specifically about solid aluminium and stainless steel pieces, 500kg in all, guess it won't reach hot enough temperatures.
660degreesC for Aluminium and 1500degreesC for Stainless.... Which seems pretty low for re-entry standards?

As of 10:30 a.m. EDT on Sept. 23, 2011, the orbit of UARS was 100 miles by 105 miles (160 km by 170 km). Re-entry is expected late Friday, Sept. 23,
or early Saturday, Sept. 24, Eastern Daylight Time. Solar activity is no longer the major factor in the satellite’s rate of descent. The
satellite’s orientation or configuration apparently has changed, and that is now slowing its descent. There is a low probability any debris that
survives re-entry will land in the United States, but the possibility cannot be discounted because of this changing rate of descent. It is still too
early to predict the time and location of re-entry with any certainty, but predictions will become more refined in the next 12 to 18 hours.
Oh Lordy now you've got me...pretty hot I would imagine as specified aluminum etc can withstand high temps...but by the time it lands things will
have cooled a bit...However i wouldn't suggest touching any of it!
Phage would be your man on this!....
But I have heard quotes of 1500 degrees???
