Fusion is the alloy add-on for SimpleCore/Simple Ores2. It adds steel (and steel items) and the fusion furnace (an alloy furnace); from Simple Ores 2, it adds 3 more alloys and items made from them: bronze, thyrium and sinisite. Fusion recycling, from akkamaddi's Addenda (formerly Simple Fusion Recycling), was merged into Fusion around Minecraft 1.14.4/1.15 or so.

For Minecraft Forge 1.16.3 and later, SimpleCoreLib is required.
For Minecraft Forge 1.14 through 1.16.1, Simple Ores2 is required.
SimpleCore API is no longer required for Minecraft 1.12.2 or earlier.
