Strength also has to do with the ratio you are using. A 6.50 gear with a very small tooth count pinion is more prone to fail due to deflection than a 4.56 with a bigger pinion. Yes, the alum will deflect more than steel, but the ratio is the deciding factor. Think about what is happening when the ring gear moves away from the pinion. The contact area gets smaller and moves to the thinner/weaker part of the gear. As I said in my previous post the Alum deflects too much for the gear ratio I'm using. It might not for the gear you are using.
