Alloys and Smelting

Alloys and Smelting

If you’re playing with Base Metals you will find many new ores: both real ores like Silver, Copper, and fantasy ores like Adamantium. Some of the metals you will be able to work with aren’t dug directly out of the ground, but made from alloying ores together such as Bronze from Copper and Tin.

New Ores

You will encounter several new ores in the overworld. Most of these ores can be used to make all the standard items and blocks, including tools, armor, weapons, doors, etc. Some of them will also be useful for the production of specific items such as copper pipes for transporting fluid.

new ores in world


  • Hardness: 1
  • Durability: 1
  • Enchantibility: 1

Zinc is worthless on its own and is not even strong enough to forge into tools, but can be used to make the metal alloy brass by combining it with copper.


  • Hardness: 3
  • Durability: 1
  • Enchantibility: 2

Tin is an extremely soft metal that is not very useful by itself, but can be combined with copper to make bronze.


  • Hardness: 4
  • Durability: 4
  • Enchantibility: 5

Copper is soft, easy to work, and fairly abundant. It is needed to make bronze and brass metal alloys.


  • Hardness: 5
  • Durability: 4
  • Enchantibility: 6

Silver is a soft, shiney metal that is valued for both is beauty and its alchemical uses.


  • Hardness: 1
  • Durability: 1
  • Enchantibility: 1

Lead is a very soft metal that is best known for being very heavy and somewhat toxic. Lead tools are fragile, but can dish out a lot of damage when used as weapons.


  • Hardness: 4
  • Durability: 4
  • Enchantibility: 7

This metal is as soft as copper, but it has alchemical properties and forms the metal alloy Invar when mixed with iron.


  • Hardness: 3
  • Durability: 5
  • Enchantibility: 15

This metal is soft, but with decent durability and strong enchantibility.


  • Hardness: —
  • Durability: —
  • Enchantibility: —

Mercury metal is a liquid, so it cannot be used like other metals. However, it is an essential ingredient for making the fantasy metal alloy Mithril.

Introducing the Crack Hammer

All ores (and some other blocks) can now be ‘crushed’ by a new tool: the Crack Hammer.


The Crack Hammer is created by first crafting a Block out of ingots, such as Block of Iron. For cobblestone, smelt the Stone block.

crackhammer recipe

Next, throw the ore, ingot, or other item you wish to smash onto the ground in front of you.

crackhammer setup

Now right click on the ground below the item to smash. It will produce a new item, usually a ‘powder’ if you are smashing ore but there are other things to be smashed as well.

There are also powered machine blocks that will automate this task for you.

Alloying Metals

Now that you have produced some powdered ore using the Crack Hammer, you can blend these powders together to produce new metals with valuable properties.

Alloys are produced by taking the powders you have crushed and mixing them in certain ratios:

making an alloy

The following common alloys can be blended from ores found in the Overworld:



brass recipe

  • Hardness: 3
  • Durability: 3
  • Enchantibility: 9

This alloy of copper and zinc (2:1 ratio) is soft, but has a beautiful golden color.


bronze recipe

  • Hardness: 8
  • Durability: 4
  • Enchantibility: 4

This alloy of copper and tin (3:1 ratio) is as hard as iron, but not quite as durable.


steel recipe

  • Hardness: 8
  • Durability: 15
  • Enchantibility: 2

This alloy of iron and carbon (8:1 ratio) is as hard as iron and much more durable.


invar recipe

  • Hardness: 9
  • Durability: 10
  • Enchantibility: 3

This alloy of iron and nickel (2:1 ratio) is slightly harder than steel, but somewhat less durable. Invar pickaxes can mine blocks that normally requires a diamond pickaxe (such as obsidian)


electrum recipe

  • Hardness: 5
  • Durability: 4
  • Enchantibility: 10

This alloy of silver and gold (1:1 ratio) can be enchanted like gold, but is a little more durable.

Magical Metals and Alloys

Some strong, magical ores can now be mined from the Nether and the End dimensions, and a few alloys can be produced from these metals:

magical metals and alloys


  • Hardness: 7
  • Durability: 7
  • Enchantibility: 7

Cold-Iron is a magical metal that is nearly as strong as iron. Tools made from cold-iron are extra effective against denizens of the Nether and any other creature that is immune to fire. A full suit of cold-iron armor will protect you from harm by fire and lava.


  • Hardness: 12
  • Durability: A lot!
  • Enchantibility: 0

Adamantine is a rare magical metal that is stronger than diamonds! Armor made from Adamantine make you practically invulnerable. Tools made from adamantine are extra effective against monsters that have more than 10 hearts of health.


  • Hardness: 10
  • Durability: 25
  • Enchantibility: 12

Star-Steel is a mysterious material that can only be found in the Ender dimension. It defies standard physics and pushes the limits of the mind. Armor made from Star Steel reduces the weight of the wearer, allowing the wearer to jump higher and fall slower. Star-Steel tools slowly repair themselves while held.


mithril recipe

  • Hardness: 9
  • Durability: 9
  • Enchantibility: 9

Harder than steel and stronger than iron, Mithril is a magical alloy of silver, mercury, and cold-iron (2:1:1 ratio). Mithral weapons are extra effective against undead.


aquarium recipe

  • Hardness: 4
  • Durability: 10
  • Enchantibility: 15

Aquarium is a magical alloy of copper, zinc, and prismarine crystals (2:1:3 ratio). Aquarium weapons are extra effective against aquatic creatures and wearing a full suit of aquarium armor will allow you to breathe underwater and provides extra protection while submerged in water.

A huge thank you to DrCyano (now retired) and his successor jriwanek for making this mod and keeping it updated!
