[[File:metal_types.jpg|thumb|300px|right|Different types of pure metals.]]'''Metal''' is a [[material]] extracted from [[ore]] at a [[smelter]], turning the ore into '''bars''' of pure metal. (One [[adamantine|special metal]] becomes wafers instead of bars.) The metal bars resulting from [[smelting]] are used to make items such as [[weapon]]s, [[armor]], [[furniture]], and [[crafts]] at a [[Metalsmith's forge|forge]].
 
−
 
 
−
Metals may sometimes be combined to form an '''alloy''' metal ([[#Alloys|see below]]), which is also measured by the bar. An alloy usually improves on the properties of its components to give more uses or increased [[Item value|value]].
 
−
 
 
−
Smelting pure ores into the corresponding bars raises the base value from that of stone (3) to that of bars (5). This value is then multiplied against the [[value#Material multipliers|material multiplier]] of the metal to give the final value for the bar.
 
−
 
 
−
==Alloys==
 
−
There are eleven pure metals in ''Dwarf Fortress'' plus a twelfth [[Adamantine|special metal]], many of which can be mixed together to create another fourteen '''alloys''' of one type or another.  In some cases, making alloys will result in an overall increase in value, or the resultant alloy will be more powerful when used to forge weapons or armor, though many alloys result in no overall increase in utility or [[Wealth|created wealth]]. (These increases in value can be compared in the "Difference" column of the table below.)
 
−
 
 
−
There are many uses for alloys:
 
−
* Increased performance for armor or weapons.
 
−
* Increased value (particularly when a silver-bearing ore is substituted for silver)
 
−
* Stretching your supply of scarce metals.
 
−
* Creating items with distinct colors (for instance, [[rose gold]] is [[Color scheme|magenta]]) for furniture, color-coding rooms or levers, or artistic constructions (including [[floor]] mosaics).
 
−
* Increasing [[thought|happiness]] or perceived [[room]] value for a dwarf who particularly likes a given alloy.
 
−
* Decreased [[fuel]] consumption if making the alloy directly from ores (e.g. [[bronze]] requires only one smelter task to make 8 bars from 2 stones of ore).
 
−
 
 
−
The number of bars used to create an alloy always equals the number of bars produced: the number of bars input equals the number of bars of output.  However, the number of bars produced from smelting ores is four times greater (X ores in = 4X bars out).

*''Combat information'' is used internally by the game to determine the [[material science|combat properties]] of weapons and armor made from this metal:
 
−
*:'''Density''': Used in conjunction with other factors - heavier weapons (higher numbers) hit with more force, light weapons tend to have less penetration. Denser armor absorbs more force from being transmitted through it as well, though low elasticity is much more reliable protection. Value shown here is g/cm<sup>3</sup>, which is the raw value divided by 10<sup>3</sup>
 
−
*:'''Impact yield''': Used for blunt-force combat; ''higher'' is better for weapons, but ''lower'' is better for armor. This is the raw value divided by 10<sup>3</sup> (i.e., kPa). 
 
−
*:'''Impact fracture''': Used for blunt-force combat; ''higher'' is better. This is the raw value divided by 10<sup>3</sup> (i.e., kPa).
 
−
*:'''Impact elasticity''': Used for blunt-force combat; ''lower'' is better. This is the raw value.
 
−
*:'''Shear yield''': Used for cutting calculations in combat; ''higher'' is better. This is the raw value divided by 10<sup>3</sup> (i.e., kPa).
 
−
*:'''Shear fracture''': Used for cutting calculations in combat; ''higher'' is better. This is the raw value divided by 10<sup>3</sup> (i.e., kPa).
 
−
*:'''Shear elasticity''': Used for cutting calculations in combat; ''lower'' is better. This is the raw value.
 
−
*General Term Explanations (From Wikipedia)
 
−
*:'''Yield Strength''' - The stress at which material strain changes from elastic deformation to plastic deformation, causing it to deform permanently.
 
−
*:'''Fracture Strength''' - The stress coordinate on the stress-strain curve at the point of rupture.
 
−
*:'''Stress''' - Force per area = F/A
 
−
*:'''Strain''' - Deformation of a solid due to stress = Stress/Young's Modulus
 
−
 
 
−
So...
 
−
:Explanations!
 
−
::'''Yield Strength''' is the amount of stress required to permanently deform (bend) a material (plastic deformation)
 
−
::'''Fracture Strength''' is the amount of stress required to permanently break (rupture) a material
 
−
::'''Elasticity''' (or ''IMPACT_STRAIN_AT_YIELD'' in RAWs) is the amount of deformation (bending) that occurs at the yield point
 
−
:Implications to ''Dwarf Fortress'' Combat
 
−
::Yield combined with Elasticity can tell what a material will do under stress (be it from a hammer, axe, or arrow)
 
−
::Higher yield means that it takes more stress to deform
 
−
::Lower elasticity means that it will deform less when stress is applied

===Preliminary Combat Testing & Analysis===

For edged weapons and armour, adamantine and steel take first and second place respectively, with iron the third best material in the game. Beyond this, bronze is in a close tie with copper  the second worst material. As in older versions, silver continues to hold steady as the worst material available (no longer beneficial with wooden training weapons being available now) in regards to edged weaponry.
 
−
 
 
−
For blunt weapons, all of the standard materials (except adamantine) perform respectably well, with a very slight edge towards steel and silver. Here is the thread with the details:

Keep in mind how unbelievably complicated this system is; nothing here should be taken as word of law. These results also ignore the impact of the ''weight'' of equipment on your dwarves. Dwarves, especially weak ones without high [[Combat skill#Equipment_skills|Armor User]] skill, will move much more slowly when wearing heavy armor and carrying heavy weapons and ammunition. This may be a more important consideration than a marginal improvement in protection.

| All six standard weapon metals perform nearly identically. Steel has a slightly higher rate of critical wounds, while silver is slightly more likely to penetrate armor. Platinum (only available as [[artifact]] weapons) has twice the density of silver and several other improved properties, making it the best metal for impact weapons, though very limited in production.

Cross referencing this table with the table at the top of this section seems to indicate that low densities, high impact fractures, and high shear fractures contribute to the killing power of edged weapons
