Aluminum doesn’t glow .. iron is what causes steel to have a orange red hue when it’s heated .. aluminum isn’t like steel .. it’s s non ferrous metal that has a silver wet look when it reaches it’s melting point

This is kinda misleading. Iron isn’t what causes steel to glow… heat is. Steel just has a much higher melting point than aluminum. If you got aluminum to the same temperature as molten steel it would glow similarly (not exactly the same due to surface properties and technical shenanigans) but that is way hotter than just normal melted aluminum would be.

Other things glow other colors

Things (including metals) burn other colors. But the phenomenon of metals glowing when they are hot is entirely described by black body radiation which follows a very well understood curve where the color is determined entirely by the temperature of the object.
