Ferrium Part is a low-rarity but vital device material in Arknights: Endfield, used to bridge your early-game mining, factory, and construction needs. Once you understand where Ferrium comes from and how your AIC factory chain works, making Ferrium Part becomes a repeatable routine that quietly powers much of your late‑early and mid‑game progression.
| Topic | At a glance |

| Item type | AIC product / device part crafted from Ferrium Ore in production facilities. |
| Rarity | 2★ material (common, but heavily used). |
| Main purpose | Used to produce other items, upgrade facilities, and craft advanced mining rigs and components. |
| Source material | Raw Ferrium Ore gathered from Ferrium fields in Valley IV and Originium Science Park. |
| Early-game acquisition | Manually mine Ferrium nodes, then refine in Refining Unit and process further in Fitting/Assembly units depending on blueprint. |
| Late-game acquisition | Fully automated via optimized Ferrium→Ferrium Part AIC factory blueprints and auto-mined Ferrium. |
| Key use example | Required in bulk to craft the Electric Mining Rig Mk. II (Ferrium mining rig) and other Ferrium-based materials. |
How to turn Ferrium Ore into Ferrium Part
Step 1: Gather a stockpile of Ferrium Ore
Spend some in‑game time clearing Ferrium nodes near the Core AIC plateau and in Originium Science Park using manual mining. Aim for a decent buffer, since you will need Ferrium not just for Ferrium Part but also for early Ferrium components and blueprints.
Step 2: Feed Ferrium Ore into a Refining Unit
Set up a Refining Unit in your AIC factory grid and assign a recipe that consumes raw Ferrium.
The Refining Unit’s outputs will be Ferrium‑related intermediates such as Ferrium Powder or similar processed forms that later blueprints consume on the way to Ferrium Part.
Step 3: Route refined Ferrium to a Fitting Unit
Once refining runs smoothly, connect the output conveyor or logistics path into a Fitting unit designed for device parts.
On this unit, load or select a recipe/blueprint that lists Ferrium-based refined materials as input and Ferrium Part as the final product.
Step 4: Configure recipe quantities and run the line
Every recipe has a Ferrium input cost, plus possible secondary ingredients like Originium Powder or Carbon derivatives depending on blueprint complexity. Ensure your supply of these secondary resources matches your Ferrium throughput so the line never starves, then start production and let the part‑assembly unit continuously output Ferrium Parts.
Step 5: Store Ferrium Parts and integrate them into broader logistics
Direct the output of the Fitting/Assembly unit into Storage, then from Storage to whatever consumes Ferrium Part next—rig construction, component blueprints, or trade lines. Keeping this loop closed and stable is what turns Ferrium Part from a bottleneck into a quiet background resource you rarely think about.
If you treat Ferrium Part as a central factory product instead of a throwaway material, your progression in Arknights: Endfield becomes much smoother. By securing Ferrium fields, refining efficiently, and wiring your AIC production around automated Ferrium→Ferrium Part chains, you give yourself the flexibility to expand rigs, upgrade infrastructure, and craft powerful gear without constantly worrying about this one material.
