| ALUMINUM | Where requirements are lightness, high electrical and thermal conductivity, corrosion resistance, ease of fabrication. Forms high tensile strength alloys | BAUXITE | – | – | 3.2–3.5 | Bauxite, which occurs massive, is a mixture of minerals such as diaspore, gibbsite, and boehmite with iron oxides and silica. Occurs as residual earth from weathering and leaching of rocks in tropical climates |
