Aluminum Coil: An Earth-Friendly Industrial Material

Whether a project calls for aluminum foil (thinner than 0.006 inches in thickness) or aluminum sheet (0.006 inches to 0.070 inches in thickness), aluminum coil is behind the manufacturing process. Aluminum coil is formed by taking one continuous strip of aluminum and coiling it into a roll.

Some of the advantages of aluminum coil is that it is lightweight, heavy duty and able to resist corrosion. By a process called anodizing, whereby the aluminum surface is coated with a protective oxide, that corrosion resistance can be improved even further. As a result, manufacturers who need to increase their productivity and require parts that can withstand the elements rely on aluminum coil to get the job done.

Why might they opt for aluminum coiling over another durable material like steel or copper? At about 33% the density and weight of steel, aluminum renders parts that are much lighter, thereby reducing handling costs and shipping fees. What's more, is the cost is about 50% that of copper.

In fact, according to the Air Conditioning, Heating, Refrigeration News, aluminum versus copper has become "The Great Condensing Coil Debate." In that article published by the industrial news source, while controversy stirs about one versus the other, one thing is clear. Condensing coils made from aluminum have made air conditioning more affordable. "That (aluminum coil) brought the cost of an a/c system down, making it more palatable to consumers and builders."

But the heating, ventilation and air conditioning sector isn't the only industry in which aluminum coil is used. The transportation industry, in fact, is the largest user of the product in the United States, accounting for close to 30% of all that is produced in the nation. Indeed, the average car driven in this country contains over 275 pounds of aluminum, and some luxury car makers use aluminum sheeting to make the entire bodies of their vehicles. Perhaps that's why aluminum has become the most abundantly produced non-iron metal.

In the construction industry, aluminum coil is also being used more and more frequently as trim to cover base materials on homes. Because the aluminum can be anodized with a decorative oxide and comes in a wide variety of colors, it provides a pleasing finishing feature. Best of all, it is easy to install, making it a nice home project for the do it yourselfer. The most typical way in which aluminum coil is put to use in homes is as a trim finish for windows, soffit boarding, siding and roof edging.

Beyond these industrial advantages, aluminum is extremely kind to the environment thanks to its ability to be recycled. That ecological friendliness is further enhanced by aluminum's ability to be recycled an infinite number of times. In the transportation industry alone, that adds up to substantial benefits to the earth. In concrete terms, the average car is made up for about 7% aluminum, yet aluminum amounts to around 40% of the total material scrap value of the average vehicle at the end of its useful life.

Q:is general aluminum sheet fire-proof?
general aluminum sheet is less fireproof than tinfoil.
Q:Aluminum foil's not magnetic, but it reacts to charged objects. Why is this?
Aluminum is a non-ferrous metal. Ferrous metals contain Iron which is magnetic. When aluminum has a charge applied to it, it acts like any conductor would, the charge has magnetic properties. the aluminum is still not magnetic, but it acts like a magnet due to the charge.
Q:Aluminum vs copper coil subwoofers?
the aluminum voice coils will get louder than the copper coils but the sensitivity is lower.ok, say you have one hdc3 copper and hdc3 aluminum.with a 1000 watts rms or smaller amplifier the copper coils will get louder.but if you go with a larger amplifier,say 1500 watts rms or more the aluminum coils will be louder.
Q:Will sodium aluminum as an ingredient, cause problems for me?
It's actually Sodium Aluminum Phosphate. It's used as a preservative in a lot of food actually. It's not exactly good for you, but it's really no more harmful than any other preservative. So basically, it's unhealthy, but you're not gonna die from eating them. EDIT: Yes I realize that Aluminum has been linked to Alzheimer's disease, but this isn't Aluminum. Aluminum is an element. This is Sodium Aluminum Phosphate. A completely different substance. When an element bonds with another element (or two) often its properties completely change. I think you'd be surprised to learn that Sodium by itself, is not only horribly volatile (it will explode in water) and will kill you if you ingested it. Iodine is also poisonous in fairly moderate doses. But when the two are bonded together (sodium iodide) it becomes an essential nutrient to the body.
Q:how many nitrogen atoms are in aluminum nitrate? (more questions..)?
aluminium nitrate Al (NO3)3 so no. of N atoms = 3 . ans NOTE NUMBER OF ATOMS OR MOLECULES IN ANY COMPOUND IS GIVEN BY AVOGADRO'S NUMBERS WHICH = 6.022X 10^23 avogadro's no. is no. of atoms in one gm atomic mass of any element avogadros no. is also no of molecules. present in one gm molar mass of any molecules. e.g. 1 gm hydrogen has = 6.022x10^23 atoms of H 2gm hydrogen has = 6.022x10^23 molecules of H in the same way 16gm of O2 hsa = 6.022x10^23 atoms 32gm O2 has = 6.022x10^23 molecules of oxygen. ANOTHER EXAMPLE;-- 44 gmCO2 has = 6.022x10^23 molecules of CO2 so to know number atoms weight should be given ( particle does not explain wt.
Q:What are uses of Aluminum Nitride?
Don't know where you looked, but this came up with very basic web search. Metallization methods are available to allow Aluminium nitride to be used in electronics applications similar to those of alumina and beryllium oxide. Among the applications of Aluminium nitride are opto-electronics, dielectric layers in optical storage media, electronic substrates, chip carriers where high thermal conductivity is essential, military applications, as a crucible to grow crystals of gallium arsenide, steel and semiconductor manufacturing. Epitaxially grown thin film crystalline aluminium nitride is also used for surface acoustic wave sensors (SAW's) deposited on silicon wafers because of the Aluminium nitride's piezoelectric properties. One application is an RF filter used in mobile phones called a thin film bulk acoustic resonator (FBAR). This is a MEMS device that uses aluminium nitride sandwiched between two metal layers.
Q:How to press multilayer aluminum sheets (aluminum sheet's thickness: 0.2mm) together and keep them inseperate after pressing?
resistance welding is a welding method that pressing the materials to be welded in an area between two poles and switching on current. the current will go through the contact surface and agjacent area, producing resistance heat effect which will heatthe materials into melting or plastic state and make the materials be welded together.
Q:White Macbook or Aluminum Macbook?
I've been researching this same thing. what I've learned is the new one pice aluminum body model is much stronger and built with a fall censer to protect the hard drive if the unit should be dropped. The screen is also lit by LED which is brighter and lasts longer than conventional screens. Save the extra $250 for it, you wont regret it. Check out the link, it clearly defines why ALUMINUM IS BETTER.
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: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.
