Iron Alloy is a type of technology material (also known as a tmat) used in the Engineering Center to progress the first eight research levels of the Vehicle tech tree.

Use

Iron Alloy is only used in the Engineering Center to progress the current research level in the Vehicle Tech Tree. The amount of Iron Alloy required to advance the tech depends on the research level (also known as a tech tier), with higher levels requiring more Alloys.

Doing so will create a Vehicle Prototype Kit (these can only be used in a Garage to create a "prototype" version of that vehicle). NOTE: Iron Alloy is only used for the first eight levels of the Vehicle Tech Tree. Afterwards, Iron Alloy is useless and Copper Alloy is used for remainder of the tech tree.

Storage

Iron Alloy stacks up to 100 in inventory slots and can be stored in certain stockpiles. They cannot be stored within a Resource Transfer Station. It can be transported by almost any vehicle with an inventory slot, though the most common type of vehicle to transport them are Trucks.

Similar to other types of materials like Basic Materials, it can be crated and stored in a Seaport or Storage Depot (each crate containing 20 Iron Alloy). Additionally, it can become a reservable crate if it was directly crated from inside the Refinery.

Tips

• Since technology materials are important to advance your faction's research, it is highly recommended not to store them in Reserve Stockpiles or Refinery personal queues.
  • As such, they should be spent or stored in visible stockpiles on the map, preferably in Refineries.
• Due to Iron only being used in the first half of the Vehicle tech tree, it is highly recommended that all Iron should be used up before it becomes useless (i.e. not being used to unlock any new vehicles).

Trivia

• Prior to Update 0.47, Iron was used for the entirety of the Vehicle Tech Tree. With the introduction to Copper, it was changed so the later half of the Tech Tree only used Copper Alloy, rendering Iron Alloy obsolete.
