Some metals like iron and tungsten glow when heated to extreme temperatures, and even when they reach a melted state. Yet some other metals such as aluminum do not glow at all even when heated beyond their melting point.
Is it just some specific properties of certain metals, or is it some of the elements within metals that can cause it to glow when heated?

Well in cases like aluminum it just melts before it gets hot enough to glow good and proper. You can keep heating the molten metal and it glows like you expect for the temperature though.

At lower temps the color of the metal itself can show through since the blackbody glow isn’t as intense in the visible range. But you get up to like 2000F anything that isn’t vapor yet is pretty much the same color.
