I use commercial .049 rings and make my own rings for my engines as well.
You can use it safely, you will really like the result.
You can see some of my videos where I use regulation rings.

The effectiveness of the aluminum alloy ring can be affected because the expansion of the metals is different (between the iron cylinder and the aluminum alloy ring), when this expansion is different as the engine takes temperature, the effectiveness is affected as the stretch fit ratio changes. So, your aluminum alloy ring will bjhe effective if and only if, the expansion ratio between cylinder and ring is maintained, that will depend as I said before, on the type of alloy of your ring and the thickness of the wall of the ring itself.
This is a Cox Tee Dee .09 r / c engine. The throttle ring is self-made in aluminum alloy, as you can see there is a reduction in thickness that I made to achieve the best engine performance in all speed ranges.
(surely if you buy a throttle ring from a genuine Cox engines representative, this will already be calculated)
Hope you can understand me.
