Default clearances and fits

ok simple question for the clever bods

I have a thin wall steel tube 25mm dia and want to get a proper tight fit on it with an aluminium boss that Im making

I plan to heat the boss up with warm air to get it to expand and fit over, like you do bearings etc, then clamp down once cooled

but what would be the interference fit size?

Heat the pipe up and measure the internal diameter.
