Bronze

Bronze requires Tin and Copper in its recipe.

It can be made by macerating Tin Ore and Copper Ore into Tin and Copper Dust. The Tin and Copper Dust can then be crafted as such to form Bronze dust:

The Bronze Dust can then be smelted into Bronze Ingots, allowing for creation of armor and tools 30% stronger than iron and for making the important Wrench for dismantling machines

OR Bronze Ingots can be crafted with Tin and Copper Ingots in the same position and quantity, like so: (However, bronze ingot cannot be crafted in Tekkit 3.0.4)
