Does anyone know what the inside of an XSPC X20 420 pump is made from?

I am planning an ITX watercooling build based around the EKWB aluminium kit: https://www.ekfluidgaming.com/ek-kit-a240g

 

But the pump-reservoir combo that comes along with it is too big/bulky for my intended case. So I have thus been looking at this pump and reservoir combo from XSPC:

Does anyone here know what the internals of the pump are made from and if it will be risky to add this pump to the loop instead? As I assume XSPC targeted their pump towards traditional copper components, can I assume it is made from copper? Or will it be steel?

 

Will steel be an issue together with aluminium?

 

Thank you!
