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:What kinds of package can use aluminum bag?
Q:What are the advantages of carbon-coated aluminum foil in lithium battery applications?
Carbon-coated aluminum foil advantage in the lithium battery applications: 1. inhibiting cell polarization, to reduce thermal effects, improve rate capability; 2. Reduce the battery internal resistance, and significantly reduces the growth cycle of the dynamic resistance;
Q:the features of aluminum-foil bag
The main material structure of aluminum-foil bag: pet/ny/al/pe(the normal package) pet/ny/al/cpp(thermophilic digestion).Waterproof,dampproof,anti-static,anti-electromagnetic interference,high mechanical strength,high thermal sealing property,wide product fraction of coverage,widely used in cosmetics,facial mask,medicinal materials,drugs,solutions,foods,PC boards,IC integrated circuit,CD driver,hard disk,LCD components,welding material,electric products,circuit board,a good sealing perfromance,high barrier degree,low oxygen transmission rate and low moisture permeability,moistureproof,antifouling,anti-radiation and anti corruption,high mechanical property,high blast resistance,good tear resistance, thermostability, low temperature resistance, elegant appearance, match package conditions of food and medicine(vacuum supply)
Q:How to tear the aluminium paper package neatly by handy techniques
Use the rule to press the tin paper and use box cutter to cut the paper in right size.
Q:Which sides do we use when conducting the electricity.
Millions of tons of aluminum foil paper is used worldwide for food package,toiletry and chemicals.most of the aluminum paper is bright for one side,and non-bright for the other side. the food can be wrapped for the two sides of paper.But I suggest that using the bright side of paper to wrap the food to improve the effect of heat conduction.the primitive tin paper is really made of tin and the tin paper is a little harder than aluminum foil. it may also bring tin smell to the food.after the aluminum price declining, the aluminum foil takes the place of tin paper in daily life.however, due to the aluminum is harmful to the brain, the present aluminum foil is painted with special layer in case of the release of aluminum.aluminum foil paper is usually used for holding food(aluminum foil paper plate) and wraping the bean sprouts and potato.
Q:What's the difference between aluminum foil paper and tin foil paper?
Tin foil is thinner than aluminum foil. Tin foil is non-toxic, but long-term use may influence the intelligence quotient of children.
Q:What kind of material does aluminum foil paper belong to?
Aluminum foil paper belongs to metal mixed material like alumina, which is a raw and auxiliary material for industry manufacture and mainly used for preventing package, articles for daily use and building.
Q:Who knows how to choose aluminum foil coating?
Choose the brand lacquer. Recently, decoration pollution is often heard . Families worry about the entailing health problems after decorating their house. Therefore, while choosing lacquer, go through the following tips.
Q:what's the dying temperature of aluminum-foil paper?
It depends on walking speed.If faster, 180 degree,otherwise 120 degree.
Q:How is the multilayer-stacked aluminum waterproof roll?
Materials in the south can resist high temperature at around 80︒.materials in the north can have its flexibility as high as 1000%. Different districts in different seasons use varying materials. Those materials are coated with aluminum foil, which is moisture proof, air tight, thermal insulation, anti-ultraviolet and wear-resisting.
