Default Re: What material is the engine made of?

The cheapest and most used aluminum alloy contains 88% Al and 12% Si (Silizium). The Silizium is rather cheap and saves a lot of energy and time, because it reduces the melting point significantly.

Cu and Mg can be added. But I doubt. A spectral analysis would be fine.
