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:Aluminum foil tape or copper foil tape, which is better at shielding?
I should say they have equal shielding abilities. But as aluminum is more likely to oxidize than copper and not easy to be soldered, copper foil tape is preferred in most of the cases. Electromagnetic shield means using elements made of conductive or ferromagnetic materials to screen at the end of stator core of a large turbo-generator, reducing additional loss and local heating in parts caused by flux leakage at the end of stator winding. In terms of communication, screening is to segregate two spaces to prevent electric field, magnetic field, and electromagnetic wave of one area from reacting to or radiating the other one. To be detailed, screening will encompass interference source that influences components, circuit, assembling, cable or the overall system.
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:What the food grade aluminum-foil paper concretely mean?
Aluminum-foil paper used in barbecue is namely aluminum foil. It can not only be used in barbecue, but also can be used to hold food in service plate. Some jerky's vacuum package is also aluminum foil.
Q:How is the welding performance of 3003 aluminum coil?
3003 aluminum coil, a kind of rust-proof aluminum, belongs to AL-Mn series alloy. With low intensity (slightly higher than commercial purity aluminum), it cannot endure heat treatment, so cold processing is adopted to increase its mechanical property: high plasticity in annealing and semi-cold hardening, low plasticity in cold hardening, good corrosion resistance., good weldability and bad machinability. It is mainly used for low load part in liquid or gaseous medium requiring high plasticity and good weldability, such as fuel tanks, gasoline or lubricant conduit. It can also be used for liquid containers and other deep drawing small load parts made by deep drawing. Aluminum wire can be used to make the rivet.3003 aluminum sheet has good formability, weldability and corrosion resistance. It is used to process parts which require good formability, corrosion resistance and weldability and lower intensity than 1xxx series alloy, such as such as kitchenware, food and chemical products processing and storage equipment, groove and tank to transport liquid product, pressure vessel and pipe processed from thin plate, cooling fin, make-up board, photocopier rollers and ship material.
Q:Why the double-sided self-adhesive foil easily layered and very smelly.
Generally speaking, both sides of double-sided self-adhesive are usually isolating membrance, not aluminum foil. Both sides need to be uncovered to use as pre-installed and inverted adhered. If one layer is aluminum foil, it's one side self-adhesive. If it's smelly, it is must made of inferior raw material with one industrial waste as self-adhesive material. This kind of raw material has strong cancerogenic effects.It's also very smelly in the making process. Campus surrounding plants also die because of the smell. What's more, its waterproof effect is also decreased. You would better not to use it.
Q:What are the characteristics of high-quality decorative foil is?
Quality decorative foil insulation, sound insulation, fire protection and easy to clean, etc., but the appearance of pro-China, to facilitate processing, construction and installation speed. At present, construction, home improvement industry has formed a decorative foil application boom.
Q:What is the principle of insulation of aluminum foil tape?
Aluminum foil itself is a good conductor of heat, directly above the package is basically not play the role of insulation, but also accelerate the loss of heat, so use the time at which wrapped some cotton insulation and then wrapped in aluminum foil.
Q:why does aluminum sheet not react with sulfuric acid nut react with hydrochloric acid?
aluminum reacts with hydrochloric acid,generating aluminium chloride which can dissolve in water. but aluminum reacts with sulfuric acid, generating aluminum sulfate which can't dissolve in water and will generate aluminum sulfate, a layer of protective film, preventing aluminum from reacting with sulfuric acid, so there is no significant phenomena.
Q:Overview of aluminum foil
Q:How to remove the oxide layer in the aluminum foil with a chemical process?
Generally, we adopt the method of alkali corrosion to remove the oxide layer on the surface of the aluminum foil.The purpose of alkali corrosion is removing the oxide layer on the surface of the aluminum foil. (Note: Technological process of the method is as follows: under normal temperature, 20% nitric acid; the process parameters is about 0.5 minutes. Pre-degrease--degrease--rinsing--rinsing--alkali corrosion--rinsing--rinsing--bright dipping--rinsing--rinsing--pure rinsing. The purpose of bright dipping is to remove surface residual black ash after alkali corrosion.Temperature:50-60 degrees; time:0.5-1 minutes.The purpose of degreasing is to remove grease on the surface of the aluminum foil.The process parameters is 0.5-1 minutes. You can use acid to wash it.
