Are the S7 heatsinks made of titanium?

Hey, I was checking out some old S7 boards and those short heatsinks kinda look like titanium, right? Am I totally off, or is there some titanium in there?

Lol, no way. Those are just cheap aluminum heatsinks, super good at conducting heat. Titanium would be pricier and not as efficient for this. Some of them are anodized, so the colors can look all fancy, like bronze or gold, depending on what they had at the time.
