Metal Density Chart
Search common metals and alloys by grade, category, or keyword. Click any row to copy the density for quoting, container planning, and weight estimation.
| Material / Grade | Category | Density | kg/m³ | g/cm³ | lb/ft³ |
|---|
- g/cm³ = kg/m³ ÷ 1000
- lb/ft³ ≈ kg/m³ × 0.06242796
- kg/m³ ≈ lb/ft³ ÷ 0.06242796
Why Density Matters in Steel Purchasing, Logistics, and Fabrication
Density is the bridge between drawings and real-world cost. Once you know the density, you can convert dimensions to weight, and weight to freight cost, handling requirements, and price-per-piece calculations. For coils and cut-to-length parts, density also helps procurement teams align mill tolerances with budget targets and container utilization.
- Freight and loading: Accurate densities reduce risk of overweight containers and unexpected surcharges.
- Quotation and budgeting: Convert mm-based dimensions into kg/ton figures with consistent assumptions.
- Processing planning: Coil length vs. weight estimates support slitting, recoiling, and cutting plans.
- Incoming verification: Typical density ranges can flag potential grade mix-ups before production.

Unit Conversions and Weight Formula
Weight = Volume × Density
- Weight (kg) = Density (kg/m³) × Volume (m³)
- Rectangular volume (m³) = Length × Width × Thickness (convert mm to m)
- g/cm³ = kg/m³ ÷ 1000
- lb/ft³ ≈ kg/m³ × 0.06242796
Sample Mini-Table (Common Materials)
| Material | kg/m³ | g/cm³ | lb/ft³ |

| Stainless Steel 304 | 7930 | 7.930 | 495.3 |
| Carbon Steel (typ.) | 7850 | 7.850 | 490.0 |
| Aluminum 6061 | 2700 | 2.700 | 168.6 |
| Copper (99.9%) | 8960 | 8.960 | 559.7 |
| Titanium Grade 2 | 4510 | 4.510 | 281.7 |
FAQs: Density in Real Projects
Why does density vary between stainless grades?
Alloying elements change the atomic structure slightly. Austenitic grades (such as 304/316) typically sit near 7.9–8.0 g/cm³, while ferritic or martensitic stainless often trends closer to ~7.7–7.8 g/cm³.
Can density change with temperature or processing?
Yes. Thermal expansion affects volume, and chemistry/process routes can shift density slightly. For safety-critical engineering, confirm the value stated on your material documentation and drawings.
Which density should I use if the exact grade is unknown?
Use a clearly stated assumption (for example: carbon steel ~7850 kg/m³; stainless steel ~7930–8000 kg/m³) and note it in your quote. When the grade is confirmed, switch to the specific value in the table.
How do I go from density to price per piece?
Convert dimensions → volume → weight, then apply your price-per-ton basis. If you publish a ton-to-piece tool later, you can connect the workflow from this chart to that calculator.
