Aluminum, 5mm

Aluminium is a silvery-white, lightweight metal, the most abundant in the earth's crust but found only in combination. It has low density, has a high thermal conductivity, has excellent corrosion resistance and can be easily cast, machined and formed, is non-toxic, non-magnetic and non-sparking. Having good conductive and thermal properties, it is used to form many hard, light, corrosion-resistant alloys, in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts.
