Some of the metals listed below are available as commercially pure and many can be manufactured to be extremely pure, often 99.999% minimum, referred to as “five nines min.” For example, Aluminum 1100 is considered to be commercially pure aluminum – it is 99% pure minimum.

Aluminum, which is used in soda cans, is an element. A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound.

Aluminum occurs in igneous rocks chiefly as aluminosilicates in feldspars, feldspathoids, and micas; in the soil derived from them as clay; and upon further weathering as bauxite and iron-rich laterite. Bauxite, a mixture of hydrated aluminum oxides, is the principal aluminum ore.

Aluminium forms one stable oxide with the chemical formula Al2O3, commonly called alumina. It can be found in nature in the mineral corundum, α-alumina; there is also a γ-alumina phase.

solid

Pure aluminium of 99% or higher purity (A1 99.5, with iron and silicon as the major impurities) has many applications, for example in packaging and electronics. These alloys have good formability and corrosion resistance, high thermal and electrical conductivity, low mechanical properties and excellent workability.

Aluminum is the most abundant metal on Earth, and one of the cheapest to buy. But it used to be more valuable than gold. Aluminum is the third most common element in the Earth’s crust, but it also bonds easily with other elements.

Hans Christian Ørsted

Aluminium is the most abundant (found in large quantities) metal in the Earth’s crust . It is expensive, largely because of the amount of electricity required in the extraction process. Aluminium ore is called bauxite . Aluminium oxide has a very high melting point (over 2000°C) so it would be expensive to melt it.

English chemist Sir Humphry Davy named the element alumium in 1808 and then changed it to aluminum in 1812. British editors changed it to aluminium to be more in keeping with other elements such as potassium and sodium, while the Americans retained the spelling as aluminum.

English chemist Sir Humphry Davy named the metal, deriving the name from the mineral called alumina. Sir Humphry was not immediately decisive about the name, initially spelling it alumium in 1807. He then changed it to aluminum, and finally settled on aluminium in 1812.

Aluminum = The British pronunciation is a tongue twister. Sounding it out may help, al-loo-MIN-ee-um … There’s a second “i” in the British form of the word, aluminium, hence the extra syllable.

Aussies say: Aluminium foil. To Americans, the handy kitchen product is pronounced “a-LU-min-num” and to us Aussies it’s “al-U-min-ium.” We could just settle it once and for all and say “al foil.”

alfoil

: a native or inhabitant of Australia.

In Australia, New Zealand, South Africa, Canada, the United Kingdom, and Ireland, the word is pronounced /ˈɒzi/, hence the alternative form Ozzie; however, in the United States, it is most often pronounced /ˈɔːsi/ AW-see. Pronouncing the word with a /s/ is considered by Australians to be a canonically American error.

the land Down Under

When Aus or Aussie, the short form for an Australian, is pronounced for fun with a hissing sound at the end, it sounds as though the word being pronounced has the spelling Oz. Hence Australia in informal language is referred to as Oz.

original inhabitants

The name Australia derives from Latin australis meaning southern, and dates back to 2nd century legends of an “unknown southern land” (that is terra australis incognita). The explorer Matthew Flinders named the land Terra Australis, which was later abbreviated to the current form.

In Australia and New Zealand, the evening meal is still often called tea, whereas the midday meal is now commonly called lunch.

Tea is a large part of modern Australian culture due to its British origins. Australians drink tea and have afternoon tea and morning tea much the way the British do. Additionally, due to Australia’s climate, tea is able to be grown and produced in northern Australia.

It appears that T, also spelled tea, had a double-edged meaning in black drag culture. It could refer to a hidden truth, as Chablis uses it, and it could also refer to someone else’s hidden truth—that is, gossip: Straight life must be so boring.

The terminology around eating in the UK is still confusing. For some “lunch” is “dinner” and vice versa. From the Roman times to the Middle Ages everyone ate in the middle of the day, but it was called dinner and was the main meal of the day. Lunch as we know it didn’t exist – not even the word.

3 main meals of the day

• Breakfast – eaten within an hour or two after a person wakes in the morning. (Index)
• Lunch – eaten around mid-day, usually between 11 am and 3 pm. In some areas, the name for this meal depends on its content.
• Dinner – eaten in the evening.

Dinner and supper are both used to refer to the main meal of the day, and especially to that meal as eaten in the evening. Supper is used especially when the meal is an informal one eaten at home, while dinner tends to be the term chosen when the meal is more formal.

The abbreviation lunch is taken from the more formal Northern English word luncheon, which is derived from the Anglo-Saxon word nuncheon or nunchin meaning ‘noon drink’. The Oxford English Dictionary (OED) reports usage of the words beginning in 1580 to describe a meal that was eaten between more substantial meals.
