About Aluminum
Aluminum is a fundamental metallic element that exists in a thermodynamically stable state. It is recognized for its excellent structural integrity and widespread availability, serving as a cornerstone material in modern engineering and manufacturing. Its metallic electronic character allows for high electrical and thermal conductivity, making it indispensable for infrastructure and technology.
Due to its robust stability and abundance, aluminum is one of the most extensively characterized materials in scientific databases. It is frequently utilized in applications where weight reduction is critical without sacrificing strength, cementing its role as a primary structural metal in global industry.
Key Properties
Cross-validated computational properties for Aluminum, aggregated across 5 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of Al. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
