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:Is it aluminum good or PVC plastic good for the refrigerator inner container?
The aluminum is good because it can preserve the temperature!
Q:Is the aluminum coil with damaged side still useful?
The side of tire, also called side wall, is the thinnest and most fragile. Side wall damages can be divided into swell and scratch. The swell is often caused by external force (The car is trapped in pit or on curb when you are driving fast). It can cause the cord thread break so that the rubber of the tire side wall cannot be fixed and tightened. The size of the swell is often as big as that of an one-yuan coin and will become bigger as the traveling distance increases. Under such circumstance, it is recommended to replace the tire. Scratch is usually caused by bad roads or debris on the road. It is recommended to replace the tire if the scratch in the side wall is obvious and the cord thread break. If the front wheels have such damages, the tire should be replaced as soon as possible (Because the steering, braking and driving is mainly based on the front wheels.). If there is no spare tire on site, change the front damaged tire with the rear tire and drive to an appropriate place.
Q:What's the function of aluminum foil
It can be used to wrap the food to cook(by pot), like barbeque.
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:Aluminum corrosion resistance is mainly reflected in what areas?
The second is resistant to salt spray corrosion test conditions generally in the 35 oC, 3% salt spray environment requires 500 hours can not have spots of corrosion. Salt spray corrosion resistance is directly related to the heat transfer sheet length of life. In coastal areas, due to the high salt content in the air, so the heat transfer sheet of salt spray corrosion resistance have high requirements;
Q:Is aluminum foil rubber & plastic thermal insulated material expensive?
1. Thermal insulated sponge board, soundproof rubber & plastic cotton, high-temperature-resistant material. Price: 5.8 yuan. 2. Aluminum Foil Rubber & Plastic Thermal Insulated Cotton. Price: 2.5 yuan. 3. Aluminum Foil Self-Adhesive Thermal Insulated Cotton Rubber & Plastic Board. Price: 4.8 yuan. The above prices are from Internet and for your reference only.
Q:What is the formula to calculate the wall thickness of aluminum coil?
Aluminum coil thickness*aluminum coil width*aluminum coil curl*aluminum density (the density of aluminum alloy: 2.73, the density of pure aluminum: 2.71)
Q:How to prevent aluminum foil from wrinkling?
Due to the strip shape is serious bad, folding formed in the process of aluminum foil coiling or expanding. Its essence is that its tension is not enough to make the box surface flattening. For a device with the tension of 20 mpa, the box surface flatness shall not be greater than 301. When it is more than 301, it will wrinkle inevitably. Due to the rolling aluminum box often bear the bigger tension than follow-up processing, some aluminum foil that just show the bad strip shape when rolling turn to wrinkle when cutting or used after annealing. Main reasons of wrinkling are due to poor flatness controlling, including incorrect roll grinding ,unreasonable roll shape controlling, unreasonable parameter controlling of rolling and cutting process, bad incoming material strip shape and incorrect strip shape adjusting and imperfect precision of sleeve or tube core. Main reasons of wrinkles: The large amount of pressure make the rolling uneven or coiling lack tension. Improper controlling of roll shape or rolling pressure is too low; Uneven thickness of billet, bad flatness or shear wave. Winding shaft precision is not good and the sleeve is not round. Improper control of pressing roller pressure.
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.
