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 does aluminum foil bag should be heat-sealed?
Using the sealing machine.
Q:Is the aluminum foil tape resistant to high temperature?
The aluminum foil tape is resistant to high temperature. It is mainly for binding ducts. Heat-resisting and weather-proof are its basic properties. Aluminum foil usually can resist temperature over 300 and most of the tape can resist temperature about 180. As aluminum foil itself conducts heat, it will speed up the loss of heat. Therefore, before wrapping the aluminum foil, you can put some thermal insulation cotton inside.
Q:Performance of aluminum foil and how does it insulate heat? Describe it precisely and in detail and better give the source
Aluminum foil can’t insulate heat by itself but it has strong conductivity for heat. Its function is to reflect heat source.
Q:how to separate the aluminum sheet in plastic?
Put them into clean water if both of them won’t react with water, and aluminum sheet will sink into the bottle, then fish up them separately.
Q:How to calculate the wall thickness with the gross weight of aluminum coil known?
Gross weight*density=volume volume÷(aluminum sheet *width)=thickness
Q:How about the specifications and prices of aluminum foil thermal insulated hose?
Aluminum foil hose is made by winding aluminum foil glass fiber cloth and steel wool on both sides. It has several types including square hose, circular hose, composite hose and thermal-insulated hose. Since it has good fire resistance and flexibility, it can be used in the ventilation o high-rise buildings. Aluminum foil thermal-insulated hose is made by stuffing glass wool between the two layers of aluminum foil on both sides to preserve the internal heat. Coated with aluminum foil Mylar, aluminum foil hose is internally supported by spiral steel wires. By bonding the aluminum foil Mylar on the steel wires and reinforcing the adhesion and tension in the basement layer, aluminum foil hose is characterized by good resilience, fire resistance and safety, thus it is easy for construction. aluminum foil hose is used in dust absorption and air exhaustion such as air exhaustion of public baths.
Q:What's the important characteristic and the advantages of aluminum food package bag
AL have the characteristics of strong obstruction,transmittance.The common interior layer of PE and the CPP high temperature cooking tool are used.
Q:Can I use dyne pen to test the wetting tension in the appearance of aluminum foil? What's the standard?
What kind of dyne pen imported from America enjoy the highest cost performance? The method can accurately measure the surface tension of the base material, surface wet strength and determine the surface factors of base material. Relative humidity should not exceed the standard since high humidity is easy to aggravate the variability of data.
Q:What is carbon coated aluminum foil?
Original aluminum conductive properties of the metal itself is already good, but for the greater enhance its conductivity, people invented a carbon-coated aluminum foil. Carbon-coated aluminum foil is referring to the conductive graphite and carbon nano-coated tablets, uniform, delicate coated on aluminum foil, aluminum foil once put on such "nano coat", it will be able to collect micro-current of the active substance and greatly reduce negative resistance between the poles, the static conductivity to maximize the performance.
Q:What's the material of aluminum foil roller
The aluminum foil roller is the interior document. The roller plant and rolling mill take the advantages of the pressure of temperature change.
