Use Router for metal work

Hello All,
I am new commer in this field, now I build my own xyz cnc table which
its working area is 600 x 1200 x 150 mm
and I mount Makita router N3701 and use it to work on wood and PCB.
Here is my silly question :=
If I change the small router to the bigger model such as RF1101kit,
Will it be able to work on a metal such as
steel , aluminium or copper ? in slow feed rate.
If it is not suitable then where can I looking for spindle head to use
for my hobby job ?

Best Regards,
