Build and Use an Alloy Smelter

Crafting the Alloy Smelter

The Alloy Smelter is one of your first major machines for combining materials. Craft it using the appropriate recipe (check your crafting guide for exact ingredients). Place it in your factory area and connect it to a power source—Tech Reborn machines require energy to operate.

Processing Alloys

Open the Alloy Smelter interface. You'll see input slots for two different materials and an output slot for the resulting alloy. Insert the materials you want to combine—common early recipes include iron and copper to make bronze, or other metal combinations.

The machine will process the materials over time, consuming energy. Collect your finished alloys from the output slot and use them to craft better tools, armor, and machine components. Different alloy combinations unlock access to higher-tier machines as you progress.
