Aluminum Alloy is one of the most important refined resources in Astroneer, especially as you start progressing beyond the early game. It’s required for crafting larger and more advanced equipment like Large Rovers, Medium Shuttles, and other critical machinery that helps you explore planets more efficiently.
The good news is that Aluminum Alloy is relatively easy to craft compared to other advanced materials, and even better—everything you need to make it can be found right on the starting planet, Sylva. Once you understand the process, you’ll be able to produce it consistently and keep your progression moving forward.
Step 1: Gather Laterite (Aluminum Resource)
The first material you’ll need is Laterite, which is the raw resource used to create Aluminum.
Laterite is commonly found underground in cave systems on Sylva. To locate it, start digging down from the surface and explore the cave layers beneath your base. It appears as a brownish, smooth resource node embedded in the terrain.
Once you’ve collected a good amount of Laterite, bring it back to your base and place it into a Smelting Furnace. Smelting Laterite will convert it into Aluminum, which is one of the two refined materials needed for Aluminum Alloy.
It’s a good idea to stockpile Aluminum early, as it’s used in many recipes beyond just Aluminum Alloy.
Step 2: Find Malachite (Copper Resource)
The second key ingredient is Malachite, which is used to create Copper.
Unlike Laterite, Malachite is typically found on the surface of Sylva, especially in mountainous or rocky gray biome areas. You’ll often see it sitting on or slightly embedded in the terrain, making it easier to spot without digging deep underground.
Once you’ve gathered Malachite, return to your Smelting Furnace and refine it into Copper.
Copper is another essential resource in Astroneer, so having extra on hand will be helpful for future crafting.
Step 3: Craft Aluminum Alloy
After you’ve smelted both Aluminum and Copper, the final step is to combine them into Aluminum Alloy.
To do this, head over to your Chemistry Lab. Place one Aluminum and one Copper into the input slots, then activate the lab. After a short processing time, the machine will produce Aluminum Alloy.
It’s a simple recipe, but incredibly valuable given how many important items require it.
Why Aluminum Alloy Matters
Aluminum Alloy is a core progression material in Astroneer. It unlocks access to larger vehicles, better transportation options, and more advanced equipment that makes exploration and automation much easier.
Because all required materials are available on Sylva, it’s one of the first “advanced” resources you can reliably farm. This makes it a great stepping stone before moving on to more complex interplanetary resource chains.
Tips for Farming Aluminum Alloy Efficiently
To make the process smoother, consider setting up a small resource loop near your base. Keep a Smelting Furnace and Chemistry Lab close together so you can quickly refine materials and craft Aluminum Alloy without running back and forth.
Bringing a tractor or rover when gathering Laterite and Malachite can also save a lot of time, especially if you plan on producing Aluminum Alloy in bulk.
Lastly, always gather more than you think you need. Both Aluminum and Copper are used in many recipes, so having extra materials will prevent unnecessary trips later on.
Final Thoughts
Aluminum Alloy is one of the easiest advanced resources to craft in Astroneer, but it’s also one of the most important. With just a bit of exploration and the right setup, you can start producing it early and use it to unlock some of the game’s most useful equipment.
Once you’ve got a steady supply, you’ll be well on your way to expanding your base, upgrading your vehicles, and exploring beyond Sylva with ease.
