So basically my idea is to make the materials work with the Tetra mod, so they can be used for tool heads, handles, etc.
This request is made partially because I may be using this in a modpack that contains Tetra.

Hi Canada! According to Nebula, Alloyed should work with Tetra as Tetra already has support for modded Steel and Bronze ingots.

Yep. Can confirm. Tetra already supports common metals like steel or bronze, so no extra compat stuff is needed. Our materials already work with Tetra.
