Aluminum cans are a ubiquitous feature in grocery stores, used as a replacement for glass bottles as a container for beverages from soda to beer. As you know, the reducing agent is one which gives up electrons. Ductility: Unlike iron metal, aluminum can be easily molded. But it reacts with steam to form aluminum hydroxide and hydrogen gas (g). The Physical properties of Aluminum are the characteristics that can be observed without changing the substance into another substance. Aluminum properties. Indiana University Northwest: Physical and Chemical Properties. It has low density, is non-toxic, has a high thermal conductivity, has excellent corrosion resistance and … Typical properties for 6061 aluminum include a tensile strength of 45,000 psi, with a yield strength of 40,000 psi. In large quantities, it is isolated from the bauxite ore. This feature makes it useful as foils, metal sheets etc. When it comes in contact with oxygen, aluminum forms an oxide skin called aluminum oxide. Aluminum catches fire easily if exposed to flame when it is in powdered form. For this reason it is very resistant to corrosion. It is also reactive with both acids and alkalis. 2) is resistant to corrosion. The raw materials from which this high performance technical grade ceramic is made are readily available and reasonably priced, resulting in good value for the cost in fabricated alumina shapes.
