# Proprietary Material Density Table This table lists the density values for the proprietary materials used in the Constructo-95 system. Use the Material ID found in the CAD file attributes to lookup the corresponding density. | Material ID | Material Name | Density (g/cm³) | Description | | :--- | :--- | :--- | :--- | | **1** | Generic Debris | 0.10 | Low-density dust/noise artifacts. | | **10** | Standard Steel | 7.85 | Common structural steel. | | **25** | Aluminum 6061 | 2.70 | Aerospace grade aluminum. | | **42** | Unobtanium | 5.55 | High-strength proprietary alloy. | | **99** | Lead | 11.34 | Heavy ballast material. | ## Formula $$ Mass = Volume \times Density $$ Note: Ensure volume is in $cm^3$ and density is in $g/cm^3$.
