How and why alloying elements are added to aluminum

Silicon (Si) 4xxx The addition of silicon to aluminum reduces melting temperature and improves fluidity. Silicon alone in aluminum produces a nonheat-treatable alloy; however, in combination with magnesium it produces a precipitation hardening heat-treatable alloy.

Aluminum Silicon Alloy - an overview | ScienceDirect Topics

The as-cast microstructure expected at room temperature is composed of a mixture of silicon particles plus the eutectic phase consisting of Al FCC /α lamellar structure with silicon containing small amounts of Al 2 Cu, Al 5 Cu 2 Mg, and Al 7 Cu 2 Fe. This structure requires solubilization to improve its mechanical properties, and T6 temper usually involves reheating the alloy up to 500 °C for 58 h, followed by

Condensing boiler - Wikipedia

Doing so would reduce fuel consumption considerably, but would quickly destroy any mild steel or cast-iron components of a conventional high-temperature boiler due to the corrosive nature of the condensate. For this reason, most condensing boiler heat-exchangers are made from stainless steel or aluminum/silicon alloy.
