Variant of aluminum
- A light, silvery metal extracted from bauxite, and a chemical element (symbol Al) with an atomic number of 13.
- If phosphoric acid is absent, aluminium, chromium and ferric hydrates are precipitated.
- Next to aluminium, tin was found to be the most effective of the metals enumerated above.
- The metals used in different combinations included tin, aluminium, arsenic, antimony, bismuth and boron; each of these, when united in certain proportions with manganese, together with a larger quantity of copper (which appears to serve merely as a menstruum), constituted a magnetizable alloy.
- In thickness, which occurred on the outside of the specimen, and the exceptional magnetic quality which has been claimed for aluminium-iron cannot yet be regarded as established.
- The processes of zincography and of algraphy (aluminium printing) are essentially the same as lithography.
