Project Description
Pure aluminum
Aluminum is the most abundant metal in the world, accounting for 8% of the Earth’s crust. The versatility of aluminum with oxygen and other metals in the earth’s crust has made it the most widely used metal after steel. Aluminum is derived from the mineral bauxite. Bauxite is converted to aluminum oxide (alumina) through the bayer process. Alumina is then converted to aluminum using electrolyte cells.
Aluminum is not found as a pure metal in nature, but its compounds are more or less present in almost all rocks, زplants and animals.
Applications of pure aluminum
The characteristics of pure aluminum include softness, high ductility and corrosion resistance. Pure aluminum also has high electrical conductivity. Pure aluminum is widely used for foil and conductive cables; Aluminum is one of the lightest metals that has a certain ratio of strength to weight of steel.
After combining with various metals, aluminum has useful properties such as strength, lightness, corrosion resistance, recyclability and ductility, and other applications.
Thermal conductivity of aluminum
The thermal conductivity of aluminum is about three times higher than that of steel, which is why; Aluminum becomes an important material for cooling or heating devices such as heat exchangers. Due to the non-toxic nature of aluminum, it is widely used in cooking utensils and kitchen appliances.
From UV to infrared, aluminum is an excellent reflector of radiant energy. The visible light reflection of aluminum metal is about 80%, which means that it is widely used in lighting fixtures. The same reflectivity properties make aluminum an ideal metal as an insulating material to protect against the sun’s rays in summer, while it insulates from heat in winter.
What is Aluminum Alloy?
“Alloy” is a combination of different metal elements that is often created to increase the strength and durability of different materials. An aluminum alloy is commonly used as the base metal in the composition, often combining with other elements such as silicon, tin, manganese or even copper and magnesium. Depending on the application; With the right combination of elements, aluminum can achieve much greater strength and in some cases can even outperform steel. Alloys have the same advantages as pure aluminum and are also relatively cost-effective because they have a lower melting point.
Aluminum is usually alloyed with copper, zinc, magnesium, silicon, manganese and lithium. Small additives are also made from chromium, titanium, zirconium, lead, bismuth and nickel.
Conclusion
Pure aluminum due to its abundance in the earth’s crust in the form of various compounds and its various properties such as softness, high ductility and corrosion resistance, has many applications in industry, production of kitchen appliances and…
