Identify Metals : 17 Steps (with Pictures) - Instructables

Aluminum is a shiny grey metal and has a clear oxide that forms on contact with air. This may not be the best thing for identifying it, but aluminums melting point is 658 C (1217 F). Also aluminum is non sparking. Aluminums density is 2.70 g/cm 3, this is a good way to identify it because you can find the density of a material by density = mass ÷ volume.
