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:Why the wall insulation aluminum foil is put in the warm side
Putting in the warm side can save the energy and equal to the temperature preservation ratio: In winter,the temperature preservation aluminium is in the interior side of wall in the north.when the temperature of wall rises, the temperature of room is comfortable and the energy consumption is reducing. If putting in the exterior side of wall, the temperature in the room can be risen only after the wall temperature being rising, and the energy consumption is increasing.
Q:Is there any way to prevent corrosion oxide coated aluminum coil?
Although color coated aluminum coil is widely used, but many companies realize such a problem, a long time will be pre-painted aluminum coil corrosion and oxidation, to solve this problem, what's a few suggestions may help you.
Q:Is aluminum tape toxic?
Aluminum tape is non-toxic. However, if the oxidation film on the surface of aluminum foil is damaged, aluminum element may deposit in the body and affect people's health. But it is not poisoned. Aluminum tape is widely used in refrigerator, air conditioning, automobile, petrochemical, bridge, hotels and so on. It uses quality pressure-sensitive adhesives (PSAs) and has various characteristics such as good stickiness, aging resistance.
Q:What are the differences between aluminum coil 3003h24 and 3a21h14?
The mechanical property references of rolled plate 3003 H24and 3A21 H14 are as follows: 3003 H24--Rm/MPa≧140-180;Rp0.2/MPa≧115;A(%)≧1-5(thickness 0.2mm-4.5mm)3A12 H14--Rm/MPa≧145-215;A(%)≧6
Q:What is the value of scrap aluminum recycling?
With the rapid growth of industrial development and urban population, the increasingly serious water pollution, water purification treatment needs are also increasing, the increasing demand for water purifying agent. Because of PAC molecules with varying amounts of a hydroxyl group, when the PAC was added turbid water source, water source continued hydrolysis under pH conditions, along with the occurrence of condensation, adsorption, precipitation and a series of physical, chemical process, so as to achieve the purpose of water purification.
Q:What are the classification of aluminum foil compound insulation material?
There are a variety of insulation materials with wide application. The commonly used ones include glass cotton products, heat insulation blankets and heat-insulated foam glass, polyurethane foam glass, etc. The glass cotton products are used in air conditioning insulation, duct insulation, polyurethane foams, extruded polystyrene board, molding of polystyrene, Bakelite resin, mineral fiber products, polyphenyl granule size, compound wood, soft wood, etc. Polyurethane foam is currently a kind of insulation material with minimum coefficient of heat conductivity of 0.018~0.024W/(m·k)in building insulation.
Q:Between Aluminum foil fibre cloth tape and pure aluminum foil tape which one is good?
It only depends on what fields do you want to use it? If it is used in explosion-proof, strapping, it is suggested that you can use fiber cloth aluminum foil tape. If considering heat conduction, electric conduction and shielding performance, it is suggested that you use the pure aluminum foil tape.
Q:Whether aluminum tape has conductivity of heat?
It is of performance of thermal conductivity. There is no distiction between aluminum or aluminum foil.Thermal conductivity is proportional to the the purity of aluminum in general.
Q:How heavy and long is the aluminum rolling on average?
The blank aluminum coil of aluminum manufacturer is about 5-6 tons, while the aluminum coil of dealer or supplier depends on the feeding frame, about 1.5-2 tons or 3 tons.
Q:Can the displacement sensor be used for real-time measurement of the aluminum coil thickness?
Yes, you can use two sensors to measure thickness, either contact sensor or laser sensor
