Q:aluminum welding advise?
Hi. You need a spherical tip on, say, a mig welder to be successful when welding aluminum. Spreads out the heat better.
Q:Is using Aluminum foil bad?
over time excessive use leeches into the system and aluminium is a toxic metal that the blood- brain can not be protect against, and causes all sorts of permanent neurological damage, alzheimers, senility, parkinsons, MS, lots of things are linked to heavy metal toxicity, proven of course. Why don't you save your brain AND save money and buy yourself a tray that fits in the toaster oven so it can be reused. Obviously your brain health should be more important than money, but if you need more reason to stop using aluminum, think about the money you are throwing away several times a week that can be saved. Of course you'd save even more money if you stopped buying expensive pre-packaged frozen foods :D but I think the health of the brain has way more value than what's in your wallet in the long run.
Q:Impact strength of aluminium 2024 composite after cryogenic?
Aluminum 2024 doesn't have a transition temperature, it absorbs about 18n-m impact strength (via charpy tests I ran three weeks ago at my College course). This was constant between -150ºC to +150°C (liquid nitrogen to a furnace). This excerpt from wiki: Cutting tools In 1982 at the Oak Ridge National Laboratories, George Wei, Terry Tiegs, and Paul Becher discovered a composite of aluminium oxide and silicon carbide whiskers. This material proved to be exceptionally strong. Development of this laboratory-produced composite to a commercial product took only three years. In 1985, the first commercial cutting tools made from this alumina and silicon carbide whisker-reinforced composite were introduced by the Advanced Composite Materials Corporation (ACMC) and Greenleaf Corporation. Leads me to believe it depends on how you mix the material in would make a difference. Silicon Carbide and aluminum make very strong tools, but would make it more brittle. The ceramic in a metallic crystal lattice (metal is a crystalline structure) would allow more voids to coalesce leading to a brittle fracture, but the initial strength would be improved because of substitution dislocations in the crystal structure (it would be more rigid, stronger, but more prone to sudden failure). Silicon carbide has low thermal expansion coefficient compared to aluminum also so when it gets really cold the aluminum would contract around the particles increasing the strength, but again, reducing ductility and causing fractures to occur more rapidly. Anyways, very interesting, you should do a bit of research on your own after this as I gave you some good places to work from (and I'm sure plenty of words to look up ;D )
Q:Why are hard drives made of aluminum?
Computer hard drives are made of aluminum platters coated with a layer of magnetic material. Each tiny magnetic domain represents one bit of information. A typical drive has a round platter of 9.5 cm in diameter with a hole of 2.5 cm diameter at the center.
Q:what is the final temperature of 250g of water whose initial Temperature is 25 C if 80-g of aluminum initially?
Given Data :-- Mass : Aluminium m(a) = 80 g, Water m(w) = 250 g Initial Temperature : Aluminium t₁ = 70 C and Water t₁' = 25 C Final Temperature of both ( aluminium and water ) = T C (assume) Since Aluminium is initially at a temperature higher than that of water, it (aluminium) will lose heat to water . Heat lost by Al = Q = mass of Aluminium x sp.heat capacity of Aluminium x Temp. change = Q = 80 x 0.215 x ( 70 - T ) cal Heat gained by water = Q' = mass of water x sp.heat capacity of water x Temp. change = Q' = 250 x 1 x ( T - 25 ) According to principle of calorimetery . = Heat lost by aluminium = heat gained by water. = 250 x 1 x ( T - 25 ) = 80 x 0.215 x ( 70 - T ) = T = 27.9 C .... ( Rounded to one decimal place )...... Answer Answer .
Q:How much is the 25mm aluminum coil at current market?
You must mean 25-wide aluminum coil. The price consists of the aluminum ingot price and processing charges. For example, if the processing price is 4500 yuan, it is relatively cheap. 25mm-wide aluminum coil is very narrow, so it will be much complicated to strip.
Q:How to identify the quality of color coated aluminum coil and sheet?
Color coated aluminum coil is a kind of aluminum coil. As for qualified color coated aluminum coil, the surface has no impression, holiday and damage through the coating, and also no ripple, scratch and swell. All these are easy to see. However, the most important is the color difference of the color coated aluminum coil which is not obvious but will influence the decoration effect. Now the surface of curtain wall aluminum sheet will also be treated with electrostatic spraying. The power coating materials can have dozens of colors and realize good decorative effect, with polyurethane, polyethylene expansion resin and epoxy resin as raw materials, high color retention pigment as auxiliaries.
Q:separate aluminium from sodium hydroxide?
Trust me. Its not worth salvaging the hydroxide. Aluminum hydroxide is unbelievably stable and that means you probably won't be able to salvage the hydroxide without doing electrolysis or something difficult like that. That's like trying to obtain hydroxide from methanol CH3OH. Oh yea you can make methanol quite easily from a halomethane by reacting it with a hydroxide of some kind. But you will not be able to remove that hydroxide at all without neutralizing it with an acid. Hydroxides are bloody awful leaving groups. That oxygen is really glued on to that carbon well. You have to really destabilize that methanol to remove that hydroxide. Same with the aluminum hydroxide. Very stable and strong bond.
Q:Science help about aluminum? 10 points?
well if you took a look at the periodic table it would answer all you questions. its a metal...metal is a solid but can be a liquid when the temperatures are increased. and this page will tell u what its obtained from.
Q:Does aluminium foil promote or stop waves?
BOTH ARE CORRECT.... COVER THE WHOLE WIRELESS MODEM WITH ALUMINUM FOIL AND GROUND IT SHALL BLOCK ALL THE WIRELESS SIGNAL. CONNECT A SMALL PIECE FOIL TO THE WIRELESS MODEM ANTENNA MIGHT INCREASE THE RANGE A BIT SOME TIME BUT USUALLY NOT WORKING WELL.
