Aluminium & Aluminium Alloy
Aluminium is the world’s most abundant metal and is the third most common element, eight percent of the earth’s crust is made from aluminum.The versatility of aluminium makes it the most widely used metal after steel.
Pure aluminium is soft, ductile, corrosion resistant and has a high electrical conductivity. It is widely used for foil and conductor cables, but alloying with other elements is necessary to provide the higher strengths needed for other applications. Aluminium alloy is one of the lightest engineering metals,It can be melted, cast, formed and machined like steel but have a strength to weight ratio superior to steel.
The major advantages of using aluminium alloy are tied directly to its’ remarkable properties. Some of these properties are outlined in the following sections.
Strength to Weight Ratio
Aluminium is a very light metal with a specific weight of 2.7 g/cm³, about a third of the weight of iron, steel, copper or brass. This is an advantage in some products and crucial in others. It is used advantageously in applications where high strength and low weight are required. It can also reduce the transportation costs.
1 cubic m³ aluminium = 2,700kg
1 cubic m³ steel = 7,800kg
Lamicall phone stand not only maintains a high quality metallic texture but also keeps the product light for we using the Aluminium alloy to make our product.
Strength of Aluminium Alloys
By appropriate alloying and treatment, aluminium alloys are available in a variety of strengths.
Some aluminium alloys have strength as high as 300 MPa and are stronger than some steels.Strength may be selected to match product needs.
Aluminium and Aluminium alloy are ductile and have a low melting point and density. In a molten condition they can be processed in a number of ways. Its ductility allows products of aluminium alloy to be basically formed close to the end of the product’s design.
Corrosion Resistance of Aluminium Alloys
When the surface of aluminium metal is exposed to air, a protective oxide coating forms almost instantaneously. Different types of surface treatment such as anodising, painting or lacquering can further improve this property.
Aluminium itself is non toxic and odourless. Its surface is smooth, easily washable and hygienic because no germs can grow on it. So you could leave our products at home without worrying about having bad effect on old people and children.
Aluminium alloy’s non sparking characteristic (against itself and other non ferrous metal) makes it an essential material for products used with highly flammable or explosive substances and atmospheres. I believe you must have experienced being zapped by static electricity every time you touch a doorknob or handle. Using aluminium alloy to make our phone stand could avoid this embarrassing situations.
In the 100 years since the first industrial quantities of aluminium were produced, worldwide demand for aluminium has grown to around 29 million tons per year. About 22 million tons is new aluminium and 7 million tons is recycled aluminium scrap. The use of recycled aluminium is economically and environmentally compelling. It takes 14,000 kWh to produce 1 tonne of new aluminium. Conversely, recycling of aluminium only requires around 5 percent of the input energy required to produce virgin aluminium metal.However,The recyclability of aluminium is unparalleled. When recycled there is no degradation in properties when recycled aluminium is compared to virgin aluminium.
Lamicall would always choose the best materials to make the best products. Besides, the founders Lamicall are very conscious of the environmental impact of their activities, that’s why we are very careful in our choice of materials, factories and processes for our products.
