Physical

Aluminium is a relatively soft, durable, lightweight, ductile and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. It is nonmagnetic and does not easily ignite. A fresh film of aluminium serves as a good reflector (approximately 92%) of visible light and an excellent reflector (as much as 98%) of medium and far infrared radiation. The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa.Aluminium has about one-third the density and stiffness of steel. It is easily machined, cast, drawn and extruded.


Aluminium atoms are arranged in a face-centered cubic 


(fcc) structure. Aluminium has a stacking-fault energy 


of approximately 200 mJ/m2.


Aluminium is a good thermal and electrical conductor, 


having 59% the conductivity of copper, both thermal and 


electrical, while having only 30% of copper's density. 


Aluminium is capable of being a superconductor, with a 


superconducting critical temperature of 1.2 Kelvin and 


a critical magnetic field of about 100 gauss (10 


milliteslas).


Chemical

Corrosion resistance can be excellent due to a thin 


surface layer of aluminium oxide that forms when the 


metal is exposed to air, effectively preventing further 


oxidation.The strongest aluminium alloys are less 


corrosion resistant due to galvanic reactions with 


alloyed copper.This corrosion resistance is also often 


greatly reduced by aqueous salts, particularly in the 


presence of dissimilar metals.

In highly acidic solutions aluminium reacts with water to form hydrogen, and in highly alkaline ones to form aluminates— protective passivation under these conditions is negligible. Also, chlorides such as common sodium chloride are well-known sources of corrosion of aluminium and are among the chief reasons that household plumbing is never made from this metal.

Q:Is there any way to prevent corrosion oxide coated aluminum coil?
These are pre-painted aluminum coil to prevent corrosion oxidation method, many enterprises to keep in mind that if you do this a few protection, then the probability of corrosion and oxidation of color coated aluminum coil will be greatly reduced, in daily production, we should be more multi summary found that many of the problems solved
Q:What's the aluminum foil tape in hydropower decorating material?
It's the thermal insulation material mninly used to twine pipelines like water pipe and smoke vent.
Q:What's the aluminum-foil bag? What's the purpose of it? Is it poisonous? Can it be uesd in food industry?
Aluminum-foil bag is a kind of bag that using the ductility of aluminum and pressed by machine. There are some poisonous metal bags like external packing of capsule,capsule mounting and packing box of milk products.
Q:How does aluminum foil tube specifications can be classified?
It can be divided into 10 centimetres, 15 centimetres and 20 centimetres. It is a kind of building materials,using thin steel as skeleton, packaging with aluminum foil.It can be used in the ventilation of fhigh-rise buildings like used in central air-conditioning. The other kind is made by stuffing glass wool between the two layers of alumnium foil on both sides to preserve the internal heat.Coated with alumnium foil Mylar, alumnium foil hose is internally supported by spiral steel wires.
Q:Is aluminum foil a kind of alloy or something else?
Aluminum foil is pure aluminum, (except for the fake) which is a kind of thermoprinting material made by calendaring aluminum into sheet. Since its thermoprinting effect is similar to that of silver foil, it is also called fake silver foil. As aluminum is soft and ductile with silvery luster, aluminum foil sheet can be made by mounting calendered aluminum sheet on the offset paper with sodium silicate, which can be used to print. But the color of aluminum foil will gradually become dark as it is easy to be oxidized and it fade due to friction and touching, so it is not applicable to the thermoprint of book covers for permanent preservation.
Q:Where to buy aluminum tape?
Aluminum tape is available in building materials market, packing material stores and advertising material stores. If not, kitchen ventilator store may be a choice.
Q:What's the difference between colored aluminum and coated aluminum foil?
According to your description, I suggest you adopt acid pickling process. The basic principle is that aluminum foil will conduct oxidation reaction after being put into the acid to change the color of aluminum foil, which will meet your requirement. The color belongs to aluminum itself not painted by people! This method can get many colors like golden and milky. Different acid ratio will lead to different color.
Q:What are the advantages of a decorative foil?
Rapid spread from urban centers in Shanghai, Beijing, Guangzhou and other parts of the country, high-quality decorative foil as a high performance electronic shielding materials and building decoration materials, due to light pollution and overcome the security issues of the glass curtain wall, more and more building decoration industry favor in recent years, a sharp increase in demand, as is generally the inner wall of the building and interior furniture decoration materials, facade and interior decoration business organizations are also widely used.
Q:Why some board mounted pills are covered with a layer of aluminum foil?
This package consists of transparent PVC rigid sheet with aluminum foil blister, PVC is currently the most widely used plastic blister pack. PVC barrier is relatively thick aluminum foil 60 microns is worse, resulting in not a long shelf life of drugs. In order to extend shelf life, while the case of pharmaceutical companies without replacing existing equipment, it added outside of large aluminum cover, called tropical aluminum industry.
Q:Waterproof aluminum foil and PVC for cupboard, which is better?
Waterproof aluminum foil is usually used in cupboard while PVC is rarely used. PVC is usually used in commode. But it's better to use PVC for cupboard. Aluminum foil paper may easily soak and damage the cupboard due to its good waterproofness if water seeps into it, so it is better to paste a whole piece of waterproof aluminum foil paper without interface through which water may seep into the cupboard. Since aluminum foil paper is an additional layer on the moisture proof particle board, it is not moisture proof and waterproof enough and thus outdated. Whether PVC board can be used for cupboard depends on manufactures. Some just use it as an advertising gimmick while some use it for cupboard bottom. Surely the latter one is more durable. Cupboard is the place that contains most water and connects with sewer.
