electric motor carcass in cast iron

[solidfede]

Bye to all,
Today I was asked to draw a carcass for an electric cast iron motor (required by the customer) with cooling channels where water-glycolns will pass.

My question is very simple and perhaps banal, is it not that then will make rust made like this?

cast iron not any.... the calories have always made them in cast iron and rarely rust and make rotten losing. However you can always think of covering the conduits with chrome or other.
