What are turbos made out of?

Turbos are primarily made from high-strength materials capable of withstanding extreme temperatures and pressures. The turbine and compressor housings are usually constructed from cast iron or aluminum alloys, while the turbine wheel is often made from inconel or titanium for their heat resistance. Additionally, components like the shaft and bearings may use specialized alloys and materials designed to endure high-stress conditions. Overall, the materials used in turbos are selected for their durability and performance under demanding circumstances.
