Detailed Description

Aluminum ( Al ), face centered cubic.

Registered in cl_MaterialFactory as "aluminum", "aluminium", "al". Heat capacity and thermal expansion are fitted against the Touloukian dataset, the effective Debye temperature curve against Desai 1984 and Cook 1975, the resistivity anchor against Hust 1984, the Kohler magnetoresistance against Lüthi 1960 and Fickett 1972, and the elastic moduli as a Wachtman curve against Blanke 1989 with the Poisson ratio derived from a constant Grueneisen parameter ( Metal::create_mech ). The implied Grueneisen parameter of the cryogenic expansion branch reads 2.19 at the split temperature, against a literature 2.1 - 2.2 for aluminum.
