Are innovatek radiators alum or copper?

[Eddie3dfx]

I picked up some auction parts the other day and one of the coupled items was an innovatek radiator. I wasn't sure if it's alum or copper, if it's alum, I will fleebay it back on there. Also, any idea if it's using a 1/4" thread?
I went on innovateks website, but even with babel translator, I couldn't get real answer.

Here is the part

Aluminum ftw.. Innovatek.. what did you expect ?

[Eddie3dfx]

Aluminum, but you know, measure twice, cut once.

I read FrozenCPU's description and it mentionned something about being built in a single piece. Only aluminium can be build as a single piece, not copper/brass, which require brazing.

Innovatek rads are indeed aluminum. Moreover, you can count on almost anything they make containing aluminum. They are all about mixing metals in their water blocks.
