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:How aluminum foil is uesd in food packaging?
Flexible packaging of aluminum foil is the use of soft composite packaging material bag container, flexible packaging technology has greatly improved mechanization and automation level food and beverage industry to speed up the modernization and socialization process of people's eating habits.
Q:What equipments are needed to produce aluminum foil bag?
It depends on whether you directly use composite aluminum foil film or raw materials that aren't well composited. If you directly use composite aluminum foil film, you may need dividing and cutting machine and bag machine. If you use raw material,you may need printing press, compound machine,dividing and cutting machine and bag machine.
Q:Who knows how to choose aluminum foil coating?
Functional coating is a remarkable technological innovation used to conduct surface treatment of the battery conductive substrate. Conductive coating is made up by Nano-sized conductive graphite and carbon, which provides good static conductivity. Micro current can absorb active substance, thus reducing the contact resistance between positive/negative electrode materials and mass flow. Using less adhesion agent, the overall capacity of the battery is improved.
Q:What's the highest temperature of aluminum foil paper?
If not considering the open fire, it is no problem that the temperature of using the electric oven exceeding 300 degree and the producing process has anneal process.the temperature has exceeded 400 degree.
Q:What's the national standard for aluminum tape?
Aluminum tape is mainly used for binding cold (hot) gas pipeline in cold (warm) gas engineering and water heater manufacturing.
Q:How to calculate each square meter of aluminum foil?
the thickness of aluminum foil is different and the price is different.some company calculate the price by square meter and some calculate by the weight.If calculate by the square meter,the length and the width units should convert into meter then multiply.
Q:The development and the market situation of aluminum foil packaging.
Aluminum foil packaging development substantially synchronized with the entire industry in the Chinese market, faster development of aluminum foil packaging, mainly for two reasons: first, Chinese flexible packaging market development and the gap between developed significantly, the proportion of small flexible packaging consumer goods and food, developed countries accounted for more than 65%, and some have more than 70 %, while China accounts for about 15% share of the past two years, a rapid increase; second, domestic plastic composite, aluminum foil composite technology continues to mature, lower production costs, to promote the popularization and application of aluminum matrix composites in the Chinese packaging market.
Q:How to classify aluminum foil according to shape?
1. Hard foil: After rolling without softening treatment (annealing) of aluminum foil, without degreasing, surface Bu there is a residual Shantou. So hard foil printing, laminating, coating must be degreased before, if used for forming can be used directly.
Q:How to wash away the oil of aluminum foil products after being pressed?
The main problem is punching oil. You can use the punching oil with good volatile and lubrication performance. It can be drying under 140 degrees. It depends on whether your supplier is volunteer to buy it.
Q:How to do with damage in aluminum foil packing for lithium battery?
It is recommended to disuse the battery, because it may explode or catch fire. Currently the maximum capacity for mobile phone battery is about 2000MA/H, so the capacity of 5400MA/H is exaggerating. However, it is not easy get an extra copycat battery.
