Systema use to make an all aluminum body, but as far as wear goes, aluminum has poor wear characteristics compared to Delrin/POM. The heavy weight of the piston and the excessive vibrational impact it applied to the gearbox combined with the poor wear characteristics of aluminum are two contributing factors as to why nobody makes aluminum pistons anymore. Systema has since discontinued the product.

I still recommend a POM based piston body with 4 steel teeth or more.

If you're smoking your piston, chances are, there is something wrong with your setup and that problem should be corrected before you attempt to just band aid the solution with super strong parts. That will only cause another part to fail, and the next part in the chain would be your gears. Replacing your piston on a regular basis would be a cheaper proposition than constantly replacing your gear set.

There are many setups that shoot over 550fps with polycarbonate pistons before with little to no wear. There shouldn't be any reason why you can't do it either.

Changing to a metal piston does not make it indestructible. Having a proper setup will make it near indestructible.
I can show you what happens to an all aluminum piston in a poorly balanced setup. I still have the result of one that lasted less than 2000 rounds.

At 500fps, I think the gear set you are using is insufficient. You should actually be using the Infinity torque up gear set, which could be why you're having problems.

When your system is undertorqued, the motor builds up a LOT of excessive energy in the process of cranking the spring. The result is that when the piston is finally released, the motor releases all of that built up potential energy and causes the sector gear to come swinging around at a very high cyclic rate and crashes in to the end of the piston before it returns to battery. Your system sounds unbalanced.

I can recommend these two gear sets to help resolve your issue:

- Systema Infinity Torque Up Gear Set
- Prometheus Max Torque Gear Set

Both require half tooth pistons and are recommended for 500-550fps setups.

Also, what battery and motor are you using?
