Smelting furnace

With a smelting furnace, you can create special alloys. You can obtain it relatively early because it’s available from level 20

Below, I provide information about which metal, in combination with what, and at what temperature will yield the desired mixture. Melting ingots is quite simple and should not pose a significant challenge

Iron Ingot + Coal = Steel Ingot     >1200°C

Magnesium Ingot + Steel Ingot = Duralumin Ingot     >1000°C

Copper Ingot + Iron Ingot = Brass Ingot     >600°C

Steel Ingot + Coal = Carbon Steel     >2400°C

Platinium Ingot + Silver Ingot = Raspite Ingot    >2800°C

Magnesium Ingot + Gold Ingot = Stolzyte Ingot    >1100°C

Steel Ingot + Silver Ingot = Szelite Ingot    >800°C

Osmium Ingot + Oil = Widii Ingot    >3000°C

Lead Ingot + Scandium Ingot = Triade Ingot    >1600°C

Silver Ingot + Gold Ingot = Pirotyne Ingot >1100°C

 

Automatic smelting machine

In the future, a faster and more efficient smelting machine will be waiting for you. The Automatic Smelting Machine allows you to smelt two types of metals at once, and it also adjusts the temperature on its own, so you don’t have to control it

There’s nothing completely free. To make the Automatic Smelting Machine work, it needs to be powered by oxygen and gasoline. It’s not overly expensive, but it’s worth noting
