Aluminium is a silver, non-magnetic, soft and ductile metal. It is a chemical element with atomic number 13 and the symbol AI. Aluminium makes up approximately 8% of the earth’s crust. It is classed as the third most abundant element, the first two are silicon and oxygen.
Aluminium is known for its low density and resistance of corrosion. Aluminium in various forms such as aluminium plate is vital and are important to the aerospace industry.
Aluminium plate is used in many products such as aeroplane parts, kitchen utensils and window frames.
Aluminium plates can be welded but because of the make-up of the metal is can only be done using a special process. Aluminium can be more expensive than steel and it may warp at high temperatures. It has a lower fatigue limit and will weaken if continually stressed.
Aluminium plates are very long-lasting and sturdy and can easily be melted down and recycled. Aluminium can last anything from 10-100 years before it will start decomposing.
Very thin aluminium plates are used to make the aluminium foil, aluminium alloy is used which contains between 92 and 99 % aluminium and is usually between 0.00017 and 0.0059 inches thick. Some people say aluminium foil is dangerous if ingested but when using it in cooking you should be fine; it will only slightly increase the aluminium in your diet.
Aluminium is only toxic to the body if a person ingests or inhales high levels of aluminium. Exposure is not usually harmful unless in very high doses.
Aluminium is used daily in many objects such as CD’s, refrigerators packaging and computers.
Aluminium can be recycled, it will go through a re-melt process, this will turn into molten aluminium, removing coatings and inks that may be present in aluminium plates.
