Alloying is combining two type of different resource cards into an alloy.

To do this you need an alloying plant or alloy factory.

There are many resources that you can only get by alloying that are required for progressions.

Alloying Plants requires 2x the resources while only producing 1x the alloy.

Alloying Factories requires 1x the resources but produces 2x the alloys.
