Is aluminium a pure substance or a mixture?
Simple answer: an element. In reality, however, the protective coating of aluminium oxide (Al2O3) effectively makes aluminium objects a mixture of an element (Al metal) and a compound (Al2O3).
Is brass made from zinc and copper?
The proportions of copper and zinc in brass can be varied over a wide range to make brass with varying properties Yellow brass is 67% copper and 33% zinc Red brass, or rose brass, is 85% copper and 15% zinc There are a number of other formulations for brass of different properties. To reduce confusion, modern usage is to avoid the term brass and speak of copper alloys.
Is aluminun foil an alloy?
No, it is not an alloy. Aluminum is an element and is a metal on the periodic table of elements with the symbol Al.In its pure form it is not very useful for forming into structural material, so it is mixed with other elements to make alloys which are more useful. Almost all aluminum used for aircraft parts or car parts or other structures is an alloy. There are a numerous variety of aluminum alloys availble to the design engineer.Edit:It should also be noted the correct spelling and pronunciation is "Aluminium" Not "Aluminum" as my American counterpart has liberally put above. There is no such element as "Aluminum" on the periodic table.Sir Humphry Davy proposed the name aluminum for the metal but this broke the standardisation of names for that particular group of elements and the correct name was deemed "aluminium" This spelling is in use in all countries apart from the USA and small pockets of her neighbouring nations.Aluminium was the spelling/name in the U.S. until 1925, when the American Chemical Society officially decided to use the name aluminum instead for reasons known only to them, much like the American date system...AL in it's pure form is not alloyed with any other materials. It is extracted from bauxite.
How do you tell the difference between alloy and aluminum?
One could measure the melting point, electrical conductivity, specific heat capacity, or other physical property. These properties would be different between pure metal and alloy, and data could be compared with that in the literature. Also, many other chemical possibilities exist exploiting the reactivity difference of individual elements. (eg boiling in NaOH would dissolve Al but not Fe). If one had access to a spectrometer, one could easily and accurately determine composition.
Is any aluminum alloy magnetic?
No. Aluminum (aluminium) is not a magnetic metal. To illustrate this, place a magnet on an aluminum soda can: it won't stick. The main magnetic metals are iron and nickel. Practically all steel alloys (iron and carbon) are attracted to magnets.
Which element is used in an alloy for light non corroding bicycle parts?
The answer is Aluminum (Al)
Why are aroplanes made from aluminum alloy rather than pure aluminum?
Pure aluminum is not strong enough as building material for airplanes. Alloy with Al are stronger.

What has the author Xing Zhu written?
Xing Zhu has written: 'The fatigue behaviour of superplastic Zn-Al eutectoid alloy'
What element is used to make heating elements in toasters?
The most common alloy is the Swedish Kanthal (Fe, Cr,Al).
Properties of a ruby?
The chemical composition of ruby is aluminum oxide (Al 2 O3). Its specific gravity is 3.99 to 4.00 and refractive index range is 1.760-1.768 to 1.770-1.779. Ruby's hardness on Mohs scale is 9. It's the next hardest mineral after diamond.
What is the name of a mountain range to the north east of the uae?
Al Hajar Mountains
Which two metals form an alloy at room temperature?
Mercury(Hg) and Aluminum(Al) form a mercury amalgam at room temperature
What are low alloy steels made out of?
Mostly iron. the "low" of the 'low alloy' can refer to both the carbon content and the prorprtion of other metals in the alloy.Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.
What is Ansar al-Sharia?
Ansar al-Sharia is any of a range of radical Islamist groups which advocate Sharia law.
What has the author Mehmet R Arvas written?
