Appearance: It is silvery, shiny and white in color. Aluminum is silvery-white in color. and in dyeing processes. (vii) Its electrical resistivity is 2.669 micro ohms/cm3 at 20°C. 6. Aluminium possesses good thermal and electrical conductivity, in each case about two-thirds of the values for pure copper.
Appearance: It is silvery, shiny and white in color. Physical and Mechanical Properties of Aluminium : (i) Pure aluminium has silvery colour and lustre, while the commercial grades show a characteristic bluish tinge. This site uses Akismet to reduce spam. Her work has been featured on The Comedy Network's "Cream of Comedy," as well as on The Edge 102.0 and XM Satellite Radio. Aluminum … Aluminum catches fire easily if exposed to flame when it is in powdered form. Reflectivity

She is an honors graduate of the Comedy Writing and Performance program at Humber College. What we do, what we can do. Care is necessary therefore, to prevent it from coming into metallic contact with other metals under conditions where moisture is present in order to avoid electrolytic action i.e., corrosion. Further, it can be easily recycled and disposal is environmentally friendly. The electrolysis of the hot oxide It is also reactive with both acids and alkalis. Extraction of aluminium on the industrial scale, Melting point: 660 °C (for AL 99,99 acc. Aluminium Physical Properties. Impermeable And Odourless. (x) It forms useful alloys with iron, copper, zinc and other metals.

In passing, it may be remarked that the aluminium alloys require higher annealing temperature, from about 350°C to 400°C. Aluminum properties are so distinct that, it is being widely used in industry, household, medicine etc. - Residential house siding Weight and density: It is very light in weight. Physical and Mechanical Properties of Aluminium : (i) Pure aluminium has silvery colour and lustre, while the commercial grades show a characteristic bluish tinge. Its oxides form alkalis like aluminum hydroxide.

2. Aluminum has an atomic number of 13, and its atomic symbol is Al. It may be considered as a vertical shaper.

Ductility: Unlike iron metal, aluminum can be easily molded.
Physical Properties of Aluminum. (ii) The high purity aluminium has a much greater resistance to corrosion than the ordinary steel. The reaction leads to the formation of manganese and aluminum dioxide. anodes is the most common method. Light Weight Sachin is a B-TECH graduate in Mechanical Engineering from a reputed Engineering college. (iii) It is ductile and malleable. A fresh film of aluminium serves as a good reflector (approximately 92%) of visible light and an excellent reflector (as much as 98%) of medium and far infrared radiation. From the Latin word "alumen" meaning "alum". Magnetic properties: It is nonmagnetic by nature. Aluminum is non-magnetic. The surface of aluminum metal is covered with a thin layer For example, the use of aluminium in vehicles reduces dead-weight and energy consumption while increasing load capacity. By mass, aluminium makes up about 8% of the Earth’s crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle below. Aluminum’s atomic number is 13, while its standard atomic weight is 26.9815. 3. Corrosion Resistance
