We've written up a guide on how to make Aluminum Alloy in Astroneer.
Astroneer is a space sandbox adventure game that takes players on a journey through space using the power of Aerospace Engineering. It takes place during the "Intergalactic Age of Discovery" of the 25th century where astronauts are out and about discovering new planets, materials, and doing their best to survive in each new environment. The game features its own crafting system where players can refine resources they've found in the wild to create useful materials in order to build and shape their own experience.
One of these materials is Aluminum Alloy.
How to Make Aluminum Alloy in Astroneer
Aluminum Alloy can be made by using the Chemistry table to combine Copper and Aluminum together. First, however, players will need to find and smelt the ores necessary to create these two metals.
Copper comes from Malachite — which can be found as green and rust-orange colored nodes that form clusters shooting straight out of the ground. They are typically found in mountainous regions and will contrast sharply against the monotone background most of this terrain provides. With Malachite ores gathered, players can return to their base and smelt them together to create Copper.
Aluminum can be made with Laterite, a circular, dark red, metallic disc-like ore of which nodes typically spawn inside caves. Depending on the cave, players may have difficulty spotting it, as it can come in a variety of heights growing out of the ground. Laterite, like Malachite, can be smelted at the player's base to create Aluminum.
Once these two materials have been made, players can take both to the Chemistry table to create Aluminum Alloy. This incredibly useful material is used to make Solar Panels, Shuttles, Rovers, and more.
