brass inside car rads?

I'm wondering too, gonna check it out next time I'm at the shop. The ones I'm curious about don't look like brass at all, they are almost a silver colour. I'm eager to read what you find.

Well, I went and checked what I've got. They were all inside plastic sides that I'd taken from radiators. Some were round and yellow(ish). I checked several and these showed no magnatism, so I'm assuming they are brass. Others were flat and several - like those old, hot water registers. They were more silvery and varied from weak to very strong magnatism so I guessing stainless steel. I'd completely forgot about them as they were in a different pile. So, I'd say everybody was right. The TUBES were brass but they're not all tubes.
