1 thou per inch is at the tighter end of the interference scale, but still within limits for steel.
Ali won't apply the same pressure as steel, and will also expand more with heat, so the forces are far less.

The other option is to bore marginally oversize, then peen/crimp the bearing in place, or just rely on some stud/bearing fit loctite. The loctite option can actually be better if you need a little bit 'give' in shaft alignment.
