Fusion and alloy seeds
Fusion combines two resources into a combined/alloy seed in the Fragment Infuser — the way to
obtain alloys that do not exist as ores. It is a data-driven recipe type
(neroagriculture:fragment_fusion), fully datapack-extendable.
How it works
Put a Resource Fragment (the primary input) in the Infuser's primary slot and the second input (an item or tag) in the secondary slot. Fusion does not consume the alloy itself, but with research enabled the machine owner must already have discovered and researched that alloy. The alloy seed takes the alloy resource's own catalog tier, so the downstream loop stays consistent. A research recipe for the alloy is required. Nero Alloy has one; third-party alloys require a suitable datapack research recipe when research is enabled.
The input Resource Fragment must refer to an enabled catalog material and carry its current tier and component version. Disabled, unknown, outdated or mismatched fragments cannot be used for fusion.
Curated built-in alloys
| Alloy | Inputs | Notes |
|---|---|---|
| Nero Alloy | Iron Fragment + Redstone | Works standalone — Core always provides Nero Alloy |
| Steel | Iron Fragment + Coal | Active when a mod supplies c:ingots/steel |
| Energized Steel | Steel Fragment + Redstone | Active when a mod supplies energized steel |
Steel and Energized Steel are dormant-safe: they only activate when a mod supplies the alloy resource, and never produce a broken recipe when it is absent.
