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 material ends is so counted?
The column beam rod in the visual profile factory when surface treatment to hang up or put the spraying profile in oxidation tank, in sections at each end of the play of a hole, so that the hook, in the cutting process, in order to avoid the holes will be seen after the installation and so on when will the cutting part of the section cut ends, this is to cause less 50mm.
Q:what's the difference between the knocking voice of aluminum sheet and stainless steel?
The voice of aluminum sheet is toneless, and the voice of stanless steel is more crisp.
Q:Is the cold storage iron tube good or the aluminum tube good?
The advantages of multi row steel aluminum parallelism of aluminum heat exchange faster than steel refrigeration so faster and almost cost steel row because aluminum does not rust so late without steel row do antirusting maintenance
Q:My aluminum deck boat has a cracked keel.?
could be possible
Q:Which is better - a steel roof or an aluminum roof?
Both okorder.com All in all, either steel or aluminum will last over 50 years, and provides great resistance to hail, wind, fire, and rain. Aluminum will last somewhat longer, as you don't have to depend on galvanized or Galvalume coatings for corrosion resistance. Steel is much more affordable, and still lasts a very long time.
Q:How much is the 60 series aluminum frame bridge standard size, how much is the size of the fan
In the Canton aluminum 60 series, the broken bridge is 59.2*67; the fan is 67.2*93
Q:Why aluminum wire immersed in copper sulfate solution, static?
Observed phenomenon: the aluminum filament appears purple red solid, the aluminum filament becomes smaller gradually, the solution gradually turns from blue to colorless
Q:Aluminum oxide and sodium metal?
Sodium hydroxide and aluminium react to form sodium aluminate and hydrogen.
Q:where can I find buyers for aluminum tabs?
Scrap yards and recyclers.
Q:Why does the hollow aluminium rolling shutter door fall off for a long time?
Aluminum Alloy thermal cooling fast, excellent seismic performance, the design of hollow base not only greatly reduce the heat conduction, but also effectively reduces the acoustic resonance effect, suitable for hot summer and warm winter area and some noise pollution area.
