The worth of Aluminum products is increasing rapidly in constructions and housing. Aluminum is incredibly popular because it is: Lightweight, Strong, and Resistant to corrosion, Durable, Ductile, Malleable, Conductive and Odorless. Aluminum is also theoretically 100% recyclable with no loss of its natural properties. It also takes 5% of the energy to recycle scrap aluminum then what is used to produce new aluminum. The most common uses of aluminum include: Transportation, Construction, Electrical and Consumer Goods.
Aluminum has the highest thermal/heat conductivity while steel and bronze have the lowest. Heat conductivity is a very important property when deciding which metal to use for a specific application.
It has extraordinary thermal shock resistance and acts as an electrical insulator in mechanical chips.
Aluminum is generally used as a cost-effective replacement for copper. Aluminum is a crucial component of L.E.D lights (light emitting diodes). Copper aluminum mixes are gaining popularity as they can harness the properties of both copper and aluminum and can be manufactured at a lower cost.
Architects and Specifiers have an increasing number of considerations to satisfy when designing rainscreen systems to meet Building Regulations. Aluminium fire resistance rating performance is one of the most important factors today and the following summary has been provided to help in this endeavour.
Solid aluminium sheets are classified as a non-combustible construction material. BS 476 part 3 covers External Fire Exposure roof tests and aluminium alloys are rated AA, the highest possible under this classification system.
Although it has just 63% of the electrical conductivity of copper, aluminum’s low density makes it the best option for long distance power lines, its corrosion-resistance helps protect wires from the elements.
In addition to power lines and cables, aluminum is used in motors, appliances, and power systems. Television antenna and satellite dishes, even some LED bulbs are made of aluminum.
Aluminum’s appearance is the reason it is used frequently in consumer goods. Smartphones, tablets, laptops, and flat screen TVs are being made with an increasing amount of aluminum. Its appearance makes modern tech gadgets look sleek and sophisticated while being light and durable. It also allows heat to dissipate quickly, keeping electronic devices from overheating.
According to British Standard BS 476, aluminium is described as non-combustible. The same set of standards gives aluminium high marks on the fire resistance versus spreading scale.
It is extremely useful to examine aluminium’s behaviour under fire conditions, with reference to its relevant properties.
Most Aluminium alloys have a melting point between 600 and 660 degrees Celsius.
Therefore when aluminium is exposed to a prolonged fire environment it will begin to melt (not burn), provided that the metal’s temperature passes the melting point.
Aluminium’s heat conductivity is, approximately, 4 times greater than iron’s while its specific heat capacity is similar to iron. Aluminium’s extremely high reflectivity compared to iron (aluminium ranges between 80 to 90%, and 5 to 25% for iron to stainless steel) allows for better resistance to thermal radiation of fire.
Aluminum corrodes but it does not rust. Rust refers only to iron and steel corrosion. Aluminum, a precious metal is rust free...Read More
