What metals are used for a spaceship?

Answer 1

Different metals are used for different parts where appropriate...there is no one metal that is best for everything.

Titanium is a common spacecraft metal, but it's very hard to machine, so look to use it for castings.

Inconel is used for very high temperatures as it retains it properties and forms a skin to protect it from corrosion at high temperatures.

Hastelloy is another metal similar to Inconel.

17-4 PH Stainless is a common steel used in aircraft / spacecraft.

All of these metals are expensive to buy and very hard to machine, which drives up cost.

Answer 2

Common metals used for spacecraft construction include aluminum, titanium, and steel alloys due to their high strength-to-weight ratio, durability, and ability to withstand extreme temperature changes in space. Additionally, materials like copper, gold, and silver are utilized for electrical components and thermal control systems.
