Q:does aluminum sheet need to conduct ROHS detection?it's metel material, how much detections should it conduct for ROHS detection?
generally, all things in Europe needs ROSH EU's requirement, mainly detect the plumbum. ROSH detection is conducted by third party institution, and its report is also provided by the third party.
Q:Does a aluminum or steel bike frame usually cost more?
With climbs like this involved its just not practical. Granted, If I was touring, I would consider steel but it's a very different sort of riding (horses for courses eh?) and I would have to really go out of my way to find a steel frame. With time trials, the bikes do need to be stiff, strong and light(although more consideration is given to aerodynamics on a TT bike)Time in the saddle is irrelevent to a competitor who will often risk a right arm to win. But can I let you into an even bigger secret? The world of 'roadies' is one of snobbery, people with steel bikes are looked at as 'stalwarts of the old school' and it's akin to turning up at a race event with pedal straps,argyle socks and a rucksack full of luncheon meat sandwiches. Now do you understand where I'm coming from? My writing style is abrasive (people say I talk that way too!) and no offence to you was intended but you did mock the other guy. EDIT2: It seems some wires were crossed somewhere then? Hard to believe but I get carried away verbally too!! The best bet is to let it lie! To be honest with you, I have never ridden climbs this bad before, over this distance (106 miles)- I'm told It's a tough one and I am determined to complete before two certain riders(workmates!) - it's a matter of honour, you understand! Happy riding mate. .
Q:Could two pieces of aluminum sheets be welded together?
Sure, two pieces of alumminum sheets can be welded together, but which kind of welding method you choose is the key point.
Q:what is the behaviour of Al2O3= aluminium oxide and SiO2= silicon dioxide when heated?
Aluminium oxide is a metal oxide and here shows it's basic properties. Silicon dioxide is a non metal oxide, so acidic Acid + base ---- salt so aluminium silicate is formed
Q:why lye and aluminum shouldn't be mixed?
Under normal circumstances, aluminum does not react with water, as an impermeable protective layer composed of aluminum hydroxide either forms within seconds or is already in place. With the addition of sodium hydroxide, the formation of a protective layer is prevented. With the production of aluminates [ Al(OH)4 ]-, the amphoteric (capable of acting as either an acid or a base) aluminum hydroxide Al(OH)3 goes in solution: 2 Al + 6 H2O -- 2 Al(OH)3 + 3 H2 Al(OH)3 + NaOH -- Na+ + [ Al(OH)4 ]- A layer of aluminum oxide previously formed by passive corrosion is dissolved by the addition of sodium hydroxide. For this reason, the reaction takes place at the beginning relatively slowly: Al2O3 + 2 NaOH + 3 H2O -- 2 Na+ + 2 [ Al(OH)4 ]- The aluminum completely dissolves and the water acts here too as an acid (for an analog, see Experiment 4.4.1). This reaction is used in drain cleaners. They are mostly made out of strong alkalis, to which alumunim or zinc has been added. The alkalis break down organic residues chemically. In addition, the formation of hydrogen leads to a bubbling effect which adds an additional mechanical cleaning mechanism. The big problem here is the formation of hydrogen gas (as well as some heat). The hydrogen gas is flammable, and if it's in a closed container, will explode
Q:Baking brownies with aluminum foil?
Do not use aluminum foil......there is a good chance it will still stick and leave little bits of foil on your brownies. I use parchment paper (and no wax paper will not work). I usually spray the pan with PAM cooking spray so the parchment paper will stay in place. Let the brownies cool completely and the entire thing should pop right out and you can slice it up.
Q:Aluminum...and planes?
The density of aluminum is MUCH lower than cast iron (thus, aluminum is LIGHTER). Because it is lighter, it would be much more ideal for applications like plane building, which is why aluminum is used over cast iron in airplanes. As well, aluminum has a protective coating called aluminum oxide which protects it from corroding in water. [Answer: see above]
Q:Steel or aluminum alloy rims?
This Site Might Help You. RE: Steel or aluminum alloy rims? Which are better? I currently have steel (kinda ugly) rims on my Chevy Blazer right now, and my roommate has some aluminum alloy rims that will fit that he wants to sell me. He hates my steel rims so much that he's willing to sell me the alloy ones for $100. Should I take it? Or just stick...
Q:aluminum elements question?
Aluminum is element 13, so it has 13 protons. This also means that it normally has 13 electrons (provided it is not in an ionic state). Normally it has 14 neutrons, but may have less or more in various isotopes.
Q:Status of aluminum sheet F
Status of aluminium plateThe F is free, and the aluminum sheet state is not limited. It is suitable for the products which have no special requirement for the working hardening and the heat treatment conditions in the forming process. The mechanical properties of the products in this state are not specifiedO is an annealed state, that is, a fully soft state, suitable for fully annealed products with minimum strength
