Metallurgical Industry
The Metallurgical Industry extracts, refines, and processes metal ores into usable metals and alloys. It focuses on metal production and transformation at the material level (chemical and physical processes)
The Metalworking Industry shapes, machines, and assembles finished or semi-finished metal products. It focuses on mechanical transformation of metals into components, tools, and structures.

| Definition | The Metallurgical Industry extracts, refines, and processes metal ores into usable metals and alloys. It focuses on metal production and transformation at the material level (chemical and physical processes). | The Metalworking Industry shapes, machines, and assembles finished or semi-finished metal products. It focuses on mechanical transformation of metals into components, tools, and structures. |
| Position in Value Chain | Upstream — produces raw or semi-finished metal materials (ingots, bars, sheets, alloys). | Downstream — uses those materials to create finished parts, tools, and products. |
| Core Processes | Mining → Smelting → Refining → Casting → Alloying → Rolling → Extrusion | Machining → Forging → Stamping → Welding → Bending → Cutting → Assembly |
| Type of Transformation | Metallurgical transformation (chemical, thermal, and phase changes) | Mechanical transformation (physical shaping, forming, removal, joining) |
| Main Outputs | Metal ingots, sheets, rods, bars, alloys, castings | Machine parts, tools, fasteners, structures, consumer and industrial products |
| Typical Facilities | Smelters, foundries, steel mills, rolling plants, refineries | Machine shops, fabrication plants, tool-and-die facilities |
| Scientific Foundation | Materials science, thermodynamics, physical metallurgy, chemistry | Mechanical engineering, manufacturing processes, precision mechanics |
| NAICS Codes | 331 — Primary Metal Manufacturing | 332 — Fabricated Metal Product Manufacturing |
| Example Industries | Iron and Steel Industry, Aluminum Industry, Copper Smelting | Tool and Hardware Manufacturing, Sheet Metal Fabrication, Machining Industry |
| Upstream Relation | Depends on Mining & Ore Processing | Depends on Metallurgical Industry for materials |
| Downstream Relation | Supplies to Metalworking, Automotive, Construction, Aerospace | Supplies to Machinery, Transportation Equipment, Construction, Consumer Goods |
