TFC Alloy Extension

English

An expansion to TerraFirmaCraft's alloy system. When your crucible mix doesn't match any known alloy recipe, you no longer have to accept useless Unknown metal. You can still get a usable, though inferior, alloy.

Inferior Alloy System

When melting metals in a crucible, if the ratios don't match any known alloy recipe, this mod checks whether one metal dominates the mix. If the dominant metal exceeds a configurable threshold (default 75%), a usable "inferior" variant is produced — impure, but still functional.

Default pure metals: Copper, Tin, Zinc, Bismuth, Gold, Silver, Nickel

Optional addon metals:

TFC-IE-Crossover (optional): Aluminum, Lead, Uranium
Firmalife (optional): Chromium

Iron Inferior System

In TFC, wrought iron is purified through repeated forging, while cast iron is the brittle, high-carbon form. This system treats wrought iron as pure iron and cast iron as inferior iron.

Two changes are always active, regardless of config:

Wrought iron items melt into wrought iron fluid (overriding TFC's default behavior of producing cast iron). Pure stays pure.
Wrought iron fluid can be directly cast into ingots via new casting recipes, a feature absent from vanilla TFC.

The alloy.enableIronInferiorSystem config toggle (disabled by default) additionally enables crucible alloy logic: when wrought iron is the dominant metal in an impure crucible mix, it produces cast iron fluid as the inferior output — just like copper/tin/zinc produce their inferior variants.

Solder

A new metal added by this mod — a tin-lead-bismuth alloy with its own fluid, ingots, buckets, and casting recipes.

Crafting Propagation

Items crafted with inferior alloy materials automatically inherit the "inferior" tag. This tag persists through TFC forging, welding, and vanilla crafting, ensuring correct fluid recovery when the item is eventually melted down. Compatible with Immersive Engineering multiblock machines — the tag is preserved through Arc Furnace and Alloy Smelter processing.

Crucible Pour Speed

Configurable pour speed multiplier (default 4×). Accelerates fluid transfer from the crucible into molds.

群峦传说合金系统扩展模组。当你在坩埚里把金属比例搞砸了，不会只剩一堆不可用的"未知"废料——只要有一种金属占比够高，你仍然能得到可用的劣等合金。

劣等合金系统

在坩埚中混合金属时，如果配比无法匹配任何已知合金配方，本模组会检查是否有某种金属占了绝大多数。如果主导金属的占比超过可配置阈值（默认 75%），就会产出一个可用的"劣等"版本——纯度不够，但照样能用。

默认支持的纯金属： 铜、锡、锌、铋、金、银、镍

可选模组扩展：

安装 TFC-IE-Crossover 后：铝、铅、铀
安装 Firmalife 后：铬

铁劣等系统

在群峦中，锻铁是经过反复锻打纯化得到的金属，铸铁则是含碳较高的脆性形态。本系统将锻铁视为纯铁、铸铁视为劣等铁。

以下两项始终生效，不受配置开关影响：

锻铁物品加热熔融后产出锻铁流体（覆写了 TFC 原版产出铸铁流体的行为）。纯的归纯的。
锻铁流体可直接浇铸成锭，原版群峦没有这个配方。

alloy.enableIronInferiorSystem 配置开关（默认关闭）额外启用坩埚合金逻辑：当锻铁在坩埚中占比不足产生合金时，主导金属锻铁会产出铸铁流体作为劣等变体——和铜/锡/锌等完全一致的劣等逻辑。

焊锡

本模组新增的金属——一种锡-铅-铋三元合金。拥有完整的流体、锭、桶和浇铸配方。

合成追溯

使用劣等合金材料合成物品时，产物会自动继承"劣等"标记。这个标记在群峦锻造、焊接、原版合成中持续传递，也兼容沉浸工程的多方块机器——电弧炉和合金窑处理过程中标记不会丢失，确保最终回熔时能正确返回劣等流体。

坩埚倾倒加速

可配置的倾倒速度倍率（默认 4×），加速坩埚向模具排出流体。
