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:Which side of the foil paper does conductive work with?
3, oil absorption foil paper into a mass, open, you can absorb the oil in the soup. The principle is the process of crumpled aluminum foil, the foil surface tension amplification. 4. Chemical reactions, aluminum foil and aluminum cans, like aluminum pots, react with acids (usually organic acids), and the salts produced by aluminum and organic acids react with acid in the stomach to form aluminium chloride (AlCl3). 5, and manufacturing aluminum foil with roller made of aluminum block out, and then cut into required length, width, and then roll up, packaging and selling
Q:What is the oxygen permeability standard of anti-static aluminum foil bags?
The peeling force GB/T1038-2000 is not less than 3.0N15mmShielding MIL-B-81705-C >40 DBShielding voltage ELA541 = 10 voltsThe inner surface resistivity is ASTM D-257 = 1011 ohms
Q:Is it good to choose a steel tube or an aluminum tube?
Aluminum tubes are mainly divided into the followingAccording to the shape of: square tube, round tube, pattern tube, special-shaped tubeIt 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, rollingBy thickness: ordinary aluminum tube and thin-walled aluminum tubePerformance: corrosion resistance, light weight.
Q:Aluminum extrusion machine, high temperature aluminum bars out of aluminum, aluminum display black or what color?
Due to the high temperature, the surface of the ingot will react with oxygen in the air, and some of the color of the aluminum ingot will be weakened! But the profiles will not fade!
Q:Aging hardness process of 6063 aluminum profile
Two 、 soft burning treatment:2.1 purpose:Materials for stretching and stretching include rolling materials, extrusion materials and forging materials:Casting - Hot Processing - cold processing - finished materialIn the process of hot or cold processing processing, material processing hardening, the strength increases or lead to work hardening, the strength increases or lead to reduced processing. In order to eliminate the work hardening, for cold working before or after the application of heat treatment is soft burning treatment. Its purpose is to make use of the material is needed.2.2 classification:Due to the different conditions of soft burning:2.2.1 part of soft burning: only part of the work hardening is eliminated, the treatment temperature is below the recrystallization temperature, the actual temperature depends on the strength, and the higher the strength, the lower the treatment temperature2.2.2 completely soft burning: treatment temperature in the recrystallization temperature or slightly higher, so that the material recrystallization, and completely eliminate the work hardening, also make the strength to the lowest stateThere is time and soft burning:2.2.3 soft burning before cold or cold start process, soft burning treatment added, usually completely soft burning, its purpose in the recovery process, and make the next function more smoothly, and the control of the organization, in order to fit for the final product requirements.2.2.4 ultimate soft burning: the main purpose is to adjust the final strength level of the finished product, that is, to adjust the chain3 processing common sense
Q:what's the size of gap while pressing 6mm aluminum sheet?
unilaterial gap is 0.1-0.15mm, and you can change the gap according to cutting effect.
Q:Structure of Aluminium Chloride?
Aluminium chloride sublimes (turns straight from a solid to a gas) at about 180°C. If it simply contained ions it would have a very high melting and boiling point because of the strong attractions between the positive and negative ions. The implication is that it when it sublimes at this relatively low temperature, it must be covalent. The dots-and-crosses diagram shows only the outer electrons.

Q:What type of aluminium sheet is a food grade?
You can inquire about our company: dexincheng Pioneer Metals corporation. Baidu will find the phone soon.
Q:What's the reason for the flash of a LED light?
This is the bad contact LED lamp gold or aluminum wire, usually, a welding wire connecting wire, arc welding off, if the two did not fill ball there may be two welding welding.
Q:What brings in more heat? Aluminum or black?
paint the aluminum black and wrap it, unless it is windy, then try painting the styrofoam, but don't use spraypaint on the styrofoam, it will melt
