Product Description:

Aluminium alloys with a wide range of properties are used in engineering structures. Alloy systems are classified by a number system (ANSI) or by names indicating their main alloying constituents (DIN and ISO).

The strength and durability of aluminium alloys vary widely, not only as a result of the components of the specific alloy, but also as a result of heat treatments and manufacturing processes. A lack of knowledge of these aspects has from time to time led to improperly designed structures and gained aluminium a bad reputation.

One important structural limitation of aluminium alloys is their fatigue strength. Unlike steels, aluminium alloys have no well-defined fatigue limit, meaning that fatigue failure eventually occurs, under even very small cyclic loadings. This implies that engineers must assess these loads and design for a fixed life rather than an infinite life.

Another important property of aluminium alloys is their sensitivity to heat. Workshop procedures involving heating are complicated by the fact that aluminium, unlike steel, melts without first glowing red. Forming operations where a blow torch is used therefore require some expertise, since no visual signs reveal how close the material is to melting. Aluminium alloys, like all structural alloys, also are subject to internal stresses following heating operations such as welding and casting. The problem with aluminium alloys in this regard is their low melting point, which make them more susceptible to distortions from thermally induced stress relief. Controlled stress relief can be done during manufacturing by heat-treating the parts in an oven, followed by gradual cooling—in effect annealing the stresses.

The low melting point of aluminium alloys has not precluded their use in rocketry; even for use in constructing combustion chambers where gases can reach 3500 K. The Agena upper stage engine used a regeneratively cooled aluminium design for some parts of the nozzle, including the thermally critical throat region.

Another alloy of some value is aluminium bronze (Cu-Al alloy).



Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, it is used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic processing|aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.

Aluminium foil is widely sold into the consumer market, often in rolls of 500 mm (20 in) width and several metres in length.It is used for wrapping food in order to preserve it, for example, when storing leftover food in a refrigerator (where it serves the additional purpose of preventing odour exchange), when taking sandwiches on a journey, or when selling some kinds of take-away or fast food. Tex-Mex restaurants in the United States, for example, typically provide take-away burritos wrapped in aluminium foil.

Aluminium foils thicker than 25 μm (1 mil) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.

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:mesohigh electronic aluminium foil
Q:Does the waterproof effect good if the SBS roll of aluminum foil used in conjunction
Generally speaking, the effect of SBS waterproof roll used in conjuction is better than a single laye.rwhen having the construction, the roll is playing the role of light-reflecting and heat-insulation.when the roll is used in conjuction, the second time should use the PE.
Q:Could ring-pull can be transformed as aluminum sheet?
Yes, but the ring-pull cans contains fewer aluminum.
Q:How does the aluminum foil bag recycle?
The paper box should be thrown to "container",and the aluminum foil bag should also be thrown to "container".the 20% of paper and the 5% of the plastic film should be disposed.the aluminum foil paper also need to be disposed together with the paper and plastic film.the rate of recycle disposal should be reached in the range of 40% to 50%.The PE part of aluminum foil is disposed by the incinerato. Then the disposed material should sent to waste plant.
Q:How to eliminate static in aliminum foil bag?
Aluminum foil bag can protect electrostatic sensitive components from electrostatic potential hazards to the highest degree. They unique four-layer structure can form an inductive cover to make things in bags isolate from static electric field. Furthermore, the inner layer is made low density polyethylene which can remove the static can avoid static generation inside the bag. This kind of hot sealable bag is translucence , so the good inside can be easily recognized outside and the product bar code can be read. It's mainly used in package of electronic elements and PC board. It can also be used in packaging industry.
Q:Can aluminum foil insulate heat?
Qualitatively, to ensure shading, not fall, opaque, non-polluting, inexpensive, for advanced cigarettes, candy and other food from moisture and decorative packaging. Extensive use of aluminum foil, for example: Aviation food packaging, general packaging meat, cigarette packaging. Experts according to the different characteristics of the application, it will be divided into more than 20 varieties.
Q:What are the trends of foil sealing technology?
With China's food processing technology continues to progress, the introduction of computer technology into the food sealing machine which, research and development of intelligent packaging technology, mechatronics, automatic packaging system configured for production packaging. Aluminum foil sealing machine packaging systems in the diagnosis and exclusion of the production process control and detection, fault will achieve full automation.
Q:Are high-temperature aluminum foil?
Are high temperature aluminum foil, aluminum foil, also known as aluminum foil, tin foil in Hong Kong was also called, is the thickness of the processed sheet with aluminum foil rolling mill in a 0.2mm or less, mainly used in the kitchen cooking, food use or it can be used to make some simple cleaning materials. Thousands of tons of aluminum foil around the world as a protective and packaging of food, cosmetics and chemicals.
Q:Does the tin foil paper or aluminum foil paper can protect people from radiation?
tin foil paper has a good gloss finish and heat reflection.because of the protection of tinm foil paper,the cigerate doesn't change with the atimulation of outside world.more importantly, it will not change the smoke influenced by air and humid environment and the tobacco will not be deterioration since the expiration date has been longer.in addition, considering the heat insulation and beautiful design, there is platinum paper in the cigerate box.we may also use tin foil paper when having a barbeque.the paper is wrapped outside,making the food cooking well qiuckly with nice smell and no cold.the grilled lamb in the resturant also wrapped tin foil paper. tin foil paper can conduct the eletricity. it also has the function of heat insulation.in summer, the tin foil paper covers house roof ,which will reflect the 60% sunlight.besides, the space between the tin foil and the roof should have 150~200mm circulated air stratum.
