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:What specification does air hose of aluminum foil have?
XPS composite duct is taking stereoplasm B1-level flame retardant poly ethylene foam as insulating layer. Double-sided embossed aluminum foil is a new composite product through one-time processing. The product quality is light, beautiful and suitable for decoration and some requirements on high-grade places. It is convenient for installation and maintenance. It's innocuous and unpoisonous and with high-pressure resistance, dampproof, air proof, low heat conductivity coefficient and long-time heat insulation performance. It can also provide a maximum ceiling height. It has a high space utilization and is an economic product that is encironmental and healithy.
Q:What kind of material does aluminum foil paper belong to?
Aluminum foil paper belongs to metal mixed material like alumina, which is a raw and auxiliary material for industry manufacture and mainly used for preventing package, articles for daily use and building.
Q:Why aluminum foil can be used in food packaging?
2.Aluminum foil barrier is very good, after the metal aluminum is oxidized by oxygen in the metal surface to form a dense layer of oxide Al2O3 protective film to prevent oxygen to oxidation of aluminum metal, of course, made with aluminum foil bags to use this layer a dense protective film can be well isolated from the outside air into the interior of the bag, serve to prevent oxidative deterioration of food is a role.
Q:Does aluminum foil bag have property of X-ray proof?
Lead is the best material of property of X-ray proof.
Q:What's the maximum temperature that high temperature resistant aluminum tape resists?
As for aluminum tape, the aluminum foil can resist high temperature of 300℃ and most tapes can resist temperature of 300℃. Since aluminum is a good conductor of heat, wrapping the tape with aluminum foil does quicken the heat loss instead of heat preservation. Therefore, it's better to use heat-insulated cotton.
Q:The thickness of aluminum foil bag is 30 silks. Is it thick or thin?
It's very thick. What's more, 30 silks should be the thickness of two sides with each side shares 15 silks.
Q:Between Aluminum foil fibre cloth tape and pure aluminum foil tape which one is good?
Considering the base material strength, the one with a reinforcing material (clip) is of course good. But considering thermal efficiency or electric fields, including construction of the above, it is not suitable. In the field of home appliance, aluminum foil is widely used. In the decoration, it is used in mending the wall.
Q:What's the difference between aluminum laminated films and aluminum foil film?
Aluminum laminated film is thin film like PP and PET steamed by vacuum and then coated with aluminum. Aluminum foil film is a film that is compounded by aluminum foil and plastic film. The alumimum coated layer is very thin with the thickness of 300-400 angstrom while the thickness of aluminum foil is about 0.01mm.
Q:What causes the velocity effect of the aluminum foil?
2, the change in the mill itself. Using cylindrical bearing of the mill, with the increase of rolling speed, roll neck bearings will float, so that the direction contained in the roll will be affected by the interaction of two mutually butting move.
Q:When baking, what is the difference between aluminum foil and oil on paper?
The role of aluminum foil is heat and fast, even heat, so that the food will not be scorched, can prevent food grilled dirty oil tank at the same time, with aluminum foil wrapped food can be lost by reducing food and nutrition, water loss. So often when things oven with aluminum foil. But remember, the general will add lemon juice to enhance the flavor when baked, but citric acid will react with these metals, carcinogenic at high temperatures. So, you can add lemon juice after baking to eat.
