7075 Aluminium rear axle weight

Well here's the weight difference between the oem steel axle and the 7075 Aluminium axle!for interest sake the outside diameter of the oem steel axle is M25mm!the 7075 obviously has a M25mm diameter with a internal 13mm hole!so the outer wall thickness is 6mm!the front specs are not far away

Not bad weight.
The 7075 is harder to machine than lesser alloys. I have machined 7075 bits myself for my bike.
Its quite heavy for an alloy too but strong.
My main concern would be the threads on the rear axle.
But you could keep a check on the nut with a torque whench from time to time.
Ideally titanium would be the best option because you could go thinner wall than standard yet keep the strength but its expensive.
Then you could get it under 50% weight.

Titanium maybe 40%!I have not yet seen 1 piece of Titanium hardware with the same dimensions as oem 50% lighter!thats even with a Racespec drilled for safety wires Titanium bolt!the walls would have to be pretty thin to drop that much weight as the oem isn't that thick at all

Genuine grade 5 is 55% of steel.
When i made my shock mount i put bigger hole down the center and made all walls thinner in every dimension so i could beat the 55%.
This would cost alot to make spindle in grade 5 though
