Q:Aluminum and Copper wiring?
Copper we all know, no problem. Alum wire is soft and will cut and scrape real easy and can not be soldered. Ni Crom is a high temp wire used in heating elements in Electric heaters. You can Weld them but more than likely it won't stay. Best is a mechanical fastener. Hard to come by. Where is this wire located...
Q:Who invented clear aluminum?
In the novel, developed from the original screenplay (which featured information that did not end up being mentioned in the film), Scotty was already aware that the chap he gave the transaprent aluminium formula to was recorded as its inventor. Therefore, the plot as intended suggested looped or self-generating causality. This is the outcome referred to in other predestination paradoxes, like the one about going back in time 100 years and becoming your own great-grandfather. The character in the film who Scotty gives the formula to is called Marcus Nichols. he was played by an American actor called Alex Henteloff. For reasons of brevity or simplicity of plot, the film leaves the viewer thinking that Scotty et al didn't know who the inventor was, but Scotty does have the line How d'you know he wasn't the man who invented it?, delivered to Dr McCoy, which could be taken as an indication that Scotty DID know and was just being a smart-**** to McCoy. As a thought experiment, this wouldn't prove the existence of multiple universes, just that the outcome was possible without changing their own future. Proof would require more information that is also missing from the screenplay and film. In reality, there is no such thing as transparent aluminium, but there are aluminium-based ceramics which are transparent.
Q:What is the causes of aluminium discolouration?
Aluminum oxides may appear in different colors depending on hydration states and other variables. Look in a CRC Handbook of Chemistry Physics if available for aluminum compounds and their colors. The colors that you see may also have as much to do with the surface finish as the color of the material on the surface. A microscopically rough surface will appear dark next to a polished surface due to light scattering. I will agree with Ling in principle, but not on details. EDS detection limits on homogeneous samples can be better than 0.1%, although not so good for elements at the light end of the detection range. Current detectors can detect chlorine (a common culprit for aluminum discoloration) at about 0.1%. Your problem with detection and one that Ling has addressed previously may be that a thin film of contamination would not be easily detected by EDS. As Ling suggests, SIMS is a good technique for detecting thin films and low concentrations. The problem with SIMS in this case may be that the detection limits are too good and the technique cannot be quantified. SIMS would detect 2 ppm of chloride and you couldn't tell for sure whether it was 2 ppm, which is probably not an issue here, or 2000 ppm, which would be significant. I would suggest x-ray photoelectron spectroscopy (ESCA or XPS) as an alternative for further study. The technique will analyze thin films (20 A) and detection limits are good enough (about 0.1%). In addition, XPS will give you information about the compounds present, e.g. whether the oxygen is aluminum oxide, aluminum hydroxide, etc. Good Luck.
Q:What is aluminium oxide sheet?
Brief introduction:Advantage:(1) good processing: anodized aluminum decorative strong, moderate hardness, easy bending forming, continuous high-speed, convenient and direct processing into products, no need for complicated surface treatment, greatly shorten the production cycle and reduce production cost.(2) good weather resistance: standard thickness of oxide film (3 m) anodized aluminum plate, indoor use for a long time, no discoloration, no corrosion, no oxidation, no rust. Anodized aluminum oxide film (10 m) can be used outdoors, and can be exposed to sunlight for a long time without discoloration.(3) strong sense: the metal surface of aluminum anodic treatment of high hardness, as gem, scratch resistance, surface is not covered with paint, keep aluminum metal color, highlight the modern sense of metal, improve product quality and added value.(4) high fire resistance: pure metal products, the surface without paint and any chemical substances, 600 degrees high temperature does not burn, does not produce toxic gases, fire protection and environmental protection requirements.(5) strong dirt resistance: no fingerprints, no stain marks, easy cleaning, no corrosion spots.(6) applicability: it is widely used in metal aluminum ceiling, curtain wall board, aluminum plastic panel, fireproof board, honeycomb aluminum plate, aluminum veneer, electrical panel, cabinet panel, furniture panel and so on.
Q:What keeps things colder- plastic wrap or aluminum foil?
Aluminum foil. It is thicker, and metal retains heat/cold longer than the thin film of plastic would. I actually use both when I freeze things like lasagna...I use a layer of plastic wrap on it first, then a layer of foil over the top. It creates an extra (albeit fine) layer of insulation.
Q:Why did the copper rust disappear when emersed in aluminum chloride?
it particularly is authentic that many deodorants, quite those categorized anti-perspirants, incorporate aluminum chloride as an lively ingredient. Aluminum chloride does decrease sweat production via the sweat glands that are placed interior the floor and are quite ample under the hands. For some people who're heavy sweaters this drying consequence is amazingly significant. despite the fact that those deodorants decrease sweat production they do no longer block the sweat glands. we are no longer attentive to any at as quickly as risky outcomes on maximum persons from making use of a deodorant containing aluminum chloride. In our very close society at present, physique hygiene and prevention of physique smell are significant. in case you do no longer use a deodorant you are able to discover your persons the two complaining or keeping off you. while you're worried with reference to the drying consequence seem for a deodorant that would not incorporate aluminum chloride.
Q:What paint is better to paint on the brushed aluminum sheet? Simple process and good adhesion!
As long as it is spray paint, adhesion is not the same, if you want to firm, it is better to paint
Q:1mm aluminum sheet, stamping, die opening, how much is it?
According to your needs, there are two practices:1, the official commodity mold, using 4-8 tons of punch or cylinder as a power to suppress, so that the mold should be around 2000 yuan.2, the use of simple mold, direct processing of an upper mold, a lower die, probably costs around 500 yuan. Or cheaper.
Q:Aluminium Reactivity?
Aluminum is very reactive so what happens is that it has a coat aluminum oxide as soon as it comes in contact with oxygen the outer layer forms aluminum oxide Al2O3. That is why Aluminum does not rust. The Al203 coat protects it.
Q:Cardboard and aluminum questions.?
You are going to hate this answer: because the answer is: It depends. Without further details of what you are trying to accomplish its hard to know. 1: For instance if you are just trying to get small sheets of aluminum...cut off the top and bottom with scissors and one straight line down the middle. But if you are looking for something more accurate you may need to use a press or just buy sheets 2: Again, without knowing details its hard to say...perhaps you should use ducktap and layer the aluminium onto the cardboard like scale armor 3: you could use glue I guess....or do a weak weld...or if you scaled the aluminum then you wouldn't ahve to connect the aluminum to itself only to the cardboard. But it all depends on how quality you want the project to look...and what you want the end product to look like. But since you are talking about cardboard and cans I'm guessing scaling the aluminum with duck tape should work for you.
