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:Haier refrigerator is now using aluminum tube material,
The aluminium material used in refrigerator is because:Aluminum costs lower prices.Now the processing of aluminum tube material (such as molding, surface oxidation treatment, copper aluminum joints, etc.) have reached a relatively advanced level.In the assembly design, are basically installed in a relatively hidden and protected place.
Q:Where can i find pure aluminum?
Aluminum foil is your best bet. According the the Reynold's wrap web site, their foil is 98.5% aluminum.
Q:can the oxide film on the surface of aluminum sheet prevent the erosion of acid liquid? Why?
yes, acid can react with aluminum oxide , generating salt and water, but its anti-corrosion will be stronger if oxide film on the surface is enough dense.
Q:Could you tell me the difference between the 6063 aluminum plate and the 5052 aluminum plate?
The difference is that, in addition to the magnesium Mg element, there is also a silicon Si element in the 6063 aluminum plate. The strength is slightly better than that of 5052
Q:What's the latest price for 6063 Aluminium bars?
Shanghai GB is cheaper, but the domestic chemical composition is relatively poor, hardness is not hard enough, I suggest you still use imported American aluminum
Q:What is the aluminum tube expanding device? What's the principle?
It can be divided into seamless aluminum tube and common extrusion pipe according to extrusion methodAccording to the precision points: ordinary aluminum tube and precision aluminum tube, in which the precision aluminum tube generally needs to be processed after extrusion, such as cold drawn, fine drawn, rolling
Q:Is aluminum foil exactly aluminum foil paper?
Yes.
Q:6063 how many degrees does the extruded aluminum bar need to be heated?
Now die-casting aluminum process according to material size, with electric furnace heating to 600-700 degrees. Small material high temperature heating, aniseed low, or too soft, not easy to move.
Q:The difference between fan copper wire and aluminum wire
The melting point of aluminum is lower than that of copper, and the motor temperature is higher, so it is easy to burn the motorBecause the motor aluminum coil naturally low rate of finished products and copper coils, prone to failure in the process of using, replace the motor will generate additional costs and losses, the static electromechanical technology suggest that you choose copper exhaust fan motor.
Q:Hello, I would like to know, as long as the national standard of aluminum rods can do the solar frame?
After doing these, according to your actual installation requirements, positioning holes, drainage holes and other finishing.
