Satisfactory has 111 alternate recipes, and choosing the right ones is the single biggest efficiency decision in the game. This is a complete, numbers-backed tier list — every recipe that’s worth your Hard Drives, organised by production area and game stage (not an alphabetical wall), with the real per-minute throughput and the raw-resource saving versus the standard recipe. Where a recipe’s value is about power rather than resources (fuels), we say so. For the full filterable database of all 111 with a live “worth it” verdict, use our Alternate Recipes Database; to plan a full chain with any alternate swapped in, use the Production Calculator.
How to unlock alternate recipes
Alternates come from Hard Drives recovered at crash sites and researched in the MAM. Each Hard Drive offers a choice of two recipes — pick one, and re-roll later if neither helps, so nothing is permanently lost. Early on, send a scout to grab Hard Drives aggressively: four or five of the picks below will reshape your whole factory.
Early-game essentials (grab these first)
If you can only chase a few Hard Drives, these remove the worst vanilla bottlenecks and set up clean scaling:
- Solid Steel Ingot (S) — 40 Iron Ingot + 40 Coal → 60 Steel/min (vs standard 45 Ore + 45 Coal → 45/min). ~33% leaner and higher throughput; take it the moment you reach steel.
- Coated Iron Plate (S) — 37.5 Iron Ingot + 7.5 Plastic → 75 Plate/min (vs 30 Ingot → 20/min). 3.75× output per machine, ~57% less iron per plate.
- Steel Rod (S) — 12 Steel Ingot → 48 Rod/min (vs 15 Iron Ingot → 15/min). 3.2× rods per constructor and ~50% leaner.
- Steel Screw (S) — 5 Steel Beam → 260 Screw/min. One machine replaces a whole screw bank (6.5× the density of rod screws).
- Adhered Iron Plate (S) — 11.2 Iron Plate + 3.8 Rubber → Reinforced Iron Plate with no screws at all; ~50% leaner. The cleanest answer to the screw problem.
Ingots
| Recipe | Inputs → output /min | Raw vs std | Tier |
|---|---|---|---|
| Iron Alloy Ingot | 40 Iron + 10 Copper Ore → 75 Iron Ingot | −33% | A |
| Leached Iron Ingot | 50 Iron Ore + 10 Sulfuric Acid → 100 Ingot | −30% | A (mid-game) |
| Pure Iron Ingot | 35 Iron Ore + 20 Water → 65 Ingot | −15% | A |
| Pure Copper Ingot | 15 Copper Ore + 10 Water → 37.5 Ingot | −33% | S (copper) |
| Solid Steel Ingot | 40 Iron Ingot + 40 Coal → 60 Steel | −33% | S |
| Coke Steel Ingot | 75 Iron Ore + 75 Petroleum Coke → 100 Steel | −25% | A (oil economy) |
Skip Basic Iron Ingot (+30% raw) and Pure Caterium Ingot (+33%) — they cost more, not less. Our steel guide covers Solid Steel in full.
Plates, rods & the screw problem
The standard Reinforced Iron Plate chain (Ingot → Rod → Screw → RIP) is the worst chokepoint in the game. Two ways to beat it:
- Skip screws: Adhered Iron Plate (11.2 Plate + 3.8 Rubber, −50%) or Stitched Iron Plate (18.8 Plate + 37.5 Wire, −31%) make RIP with no screws. Avoid Bolted Iron Plate (+10% and 250 screws/min).
- Cheaper screws: Steel Screw (5 Steel Beam → 260/min, −38%) or Cast Screw (12.5 Iron Ingot → 50/min, skips rods).
- Plates: Coated Iron Plate (−57%, S) is the standout; Steel Cast Plate (15 Iron + 15 Steel Ingot → 45 Plate, −33%) is a strong alternative once steel flows.
- Rods: Steel Rod (−50%) and Aluminum Rod (7.5 Aluminum Ingot → 52.5 Rod, −46%) both crush the standard.
Wire, cable & quickwire
- Fused Wire (S) — 12 Copper + 3 Caterium Ingot → 90 Wire/min (vs 15 Copper → 30/min). −53% and 3× output.
- Caterium Wire (A) — 15 Caterium Ingot → 120 Wire/min; superb if caterium is plentiful.
- Quickwire Cable (S) — 7.5 Quickwire + 5 Rubber → 27.5 Cable/min, needs no wire (−56%). Insulated Cable (45 Wire + 30 Rubber → 100/min, −32%) is the best high-volume cable.
- Fused Quickwire (B) — slightly heavier (+11%) but boosts quickwire throughput when you’re connector-limited.
Circuit boards, computers & connectors
- Caterium Circuit Board (S) — 12.5 Plastic + 37.5 Quickwire → 8.8/min, no copper sheets, −53%.
- Silicon Circuit Board (A) — 27.5 Copper Sheet + 27.5 Silica → 12.5/min (−43%); highest raw throughput per machine.
- Crystal Computer (A, −28%) / Caterium Computer (A, −20%) — both cut computer cost; pick by which intermediate you have spare.
- Super-State Computer (A) — the best Supercomputer recipe (−20%).
- Silicon High-Speed Connector (S, −34%) and Plastic AI Limiter (S, −35%) — big savings on two notoriously expensive parts.
Rotors, stators & motors
- Rigor Motor (S) — 3.8 Rotor + 3.8 Stator + 1.2 Crystal Oscillator → 7.5 Motor/min (vs 10+10 → 5/min), −50%. Electric Motor (−34%) is a strong oscillator-free option.
- Copper Rotor (−26%) / Steel Rotor (−20%) and Quickwire Stator (−19%) all reduce the cost of the motor sub-components.
Frames
- Steeled Frame (A, −25%) — best basic Modular Frame recipe (avoid Bolted Frame, +4% and 140 screws).
- Heavy Encased Frame (S, −38%) — the top Heavy Modular Frame recipe; Heavy Flexible Frame (−28%) is the screw-heavy alternative.
- Flexible Framework (A, −30%) for Versatile Framework; Heat-Fused Frame (−8%) for Fused Modular Frame late-game.
Concrete & construction
- Fine Concrete (S) — 15 Silica + 60 Limestone → 50 Concrete/min (vs 45 Limestone → 15/min), −54% and 3×+ output.
- Rubber Concrete (A, −52%) and Wet Concrete (refinery, high volume) for mega-builds.
- Encased Industrial Pipe (A, −21%) — cheaper Encased Industrial Beams.
Oil economy: plastic, rubber & resin
These reshape the entire oil chain and are some of the highest-value recipes in the game:
- Polymer Resin (S) — 60 Crude Oil → 130 Polymer Resin + 20 Heavy Oil Residue (−77%). Heavy Oil Residue (S) — 30 Crude → 40 HOR + 20 Polymer Resin (−75%). Together they unlock cheap plastic, rubber and fuel.
- Recycled Plastic / Recycled Rubber (S) — 30 of one + 30 Fuel → 60 of the other. Breaks the plastic↔rubber loop and roughly doubles output by spending fuel.
- Coated Cable — refinery cable using Heavy Oil Residue, handy when your oil economy is rich.
Aluminum
- Sloppy Alumina (S, −33%) — 200 Bauxite + 200 Water → 240 Alumina Solution; the standard pick for scaling aluminum.
- Instant Scrap (A, −32%, Blender) — huge Aluminum Scrap throughput when you have the blender unlocked.
- Heat Exchanger (A, −19%) — cheaper Heat Sinks.
Fuel & power — judge on MW, not raw
A raw-resource score mis-ranks fuels because they convert fluids for energy density. Judge these on power output:
- Diluted Fuel (Blender) — 50 Heavy Oil Residue + 100 Water → 100 Fuel/min. The backbone of efficient fuel power despite the “+raw” tag.
- Turbo Blend Fuel — the densest sustainable Turbofuel recipe (the refinery Turbofuel and Turbo Heavy Fuel are far more resource-hungry — use only if power-starved).
- Nitro Rocket Fuel (late-game) — top rocket-fuel power once nitrogen is available.
End-game: crystals, nuclear & diamonds
- Insulated Crystal Oscillator (S, −34%) — much cheaper oscillators, which gate a lot of late production.
- Fertile Uranium (−45%), Uranium Fuel Unit (−29%), Infused Uranium Cell (−26%) — reshape the nuclear chain.
- Oil-Based Diamonds (−75%) and Pink Diamonds (−35%) for the Converter; Dark Matter Crystallization (−33%) for Dark Matter Crystals.
Skip tier — these cost more, not less
Only take these if a specific downstream recipe forces the exact intermediate: Basic Iron Ingot (+30%), Bolted Iron Plate (+10%), Compacted Steel Ingot (+91%), Steel Canister (+167%), Polyester Fabric (+186%), Fine Black Powder (+360%), Cloudy/Petroleum Diamonds (+80% / +20%), Turbo Heavy Fuel and Dark-Ion Fuel.

Frequently Asked Questions
How many alternate recipes are there?
111 in the current version, unlocked via Hard Drives in the MAM. The Alternate Recipes Database lists every one with inputs, outputs per minute and a computed efficiency verdict.
What’s the single best alternate recipe?
It’s between Solid Steel Ingot (60 vs 45 steel/min, removes the steel bottleneck) and a screw fix (Steel Rod + Steel Screw, or screw-free Adhered Iron Plate). Screws are the worst vanilla chokepoint, so eliminating them transforms a factory.
Can I re-roll a Hard Drive?
Yes — if neither offered recipe is useful you can re-roll it in the MAM after a cooldown, so you never permanently lose a recipe.
Do alternate recipes carry over to a dedicated server?
Yes — unlocked alternates are tied to your save, so they work identically on a dedicated Satisfactory server. Running 24/7 also lets your group keep researching Hard Drives while you’re offline.
