what type of binder jetting (bj) material has aerospace and automotive applications, is temperature…

Brief Explanations:

Inconel alloy is a nickel - chromium - based superalloy. It has excellent high - temperature strength, good oxidation and corrosion resistance. These properties make it suitable for aerospace (e.g., engine components) and automotive (e.g., exhaust system parts) applications where high temperatures and exposure to various chemicals are common. Silica sand is mainly used in foundry applications for making molds. Sandstone is a sedimentary rock with relatively low strength and poor resistance compared to superalloys. Tungsten carbide is very hard but is more often used in cutting tools, wear - resistant parts rather than in the broad aerospace and automotive applications with the combination of temperature and chemical resistance as described.

Answer:

Inconel alloy
