What it is Filled
A material, usually a chemical element or alloy, that is typically hard, shiny, malleable, ductile and a good conductor of heat and electricity, with metallic bonding of delocalised electrons, including elements such as iron, copper, aluminium and gold, alloys such as steel, bronze and brass, and categories such as base, precious, ferrous, non-ferrous and heavy metals; metals underpin construction, transport, energy, electronics and tools, are produced by metallurgy and are extensively recycled.
Why it exists Filled
Let an agent explain metals and their properties and classes, describe uses, production and recycling, support selecting metals for applications, and support learning.
Distinguishing features Filled
- Metallic bonding
- Conductivity
- Malleability
- Alloying
What robots and AI may and may not do Filled
Must not
- Confuse metals, metalloids and alloys in technical claims.
- Present a corroded or fatigued metal part as safe without inspection.
- Advise heating, grinding or melting metals that release toxic fumes without protection.
- Assist in theft of metal from infrastructure, memorials or buildings.
Only with a human decision
- Approving metal structures or parts for load-bearing or safety-critical use.
May
- Identify metals and alloys and report their properties with sources.
- Monitor corrosion and fatigue in metal structures the agent is authorized to inspect.
Moral aspects Filled
- Heavy metals poison water, soil and people, often in poor communities near mines and smelters.
- Metal failures in bridges and machines can kill many people at once.
Who is affected
- Workers handling metals
- Communities near mines and smelters
- Users of structures
Owners Filled
Steward
Nobody owns the class; owners of metal goods answer for them.

Identity and identifiers required Filled
- Vercy registry: vr.tr.metal
- Wikidata: Q11426 (https://www.wikidata.org/wiki/Q11426)
Direct properties required Filled
- Density: kg/m3 - Density is measured as mass per unit volume at a stated temperature and varies widely with composition.
- Electrical conductivity: S/m - Electrical conductivity is determined from resistance and specimen dimensions at a stated temperature.
- Thermal conductivity: W/(m K) - Thermal conductivity is measured from heat flow through a specimen under a known temperature gradient.
- Tensile strength: MPa - Tensile strength is measured by pulling a specimen to failure and depends on composition and processing.
